If the leading shoots are pinched off early in the season, and again in midsummer, the bloom will be later, perhaps in September rather than in July.
PRIMULAS, or primroses, are of various kinds, some being border plants, but mostly known in this country as greenhouse and window-garden subjects. One of them is the auricula. The true or English cowslip is one of the hardy border plants; also the plants commonly known as polyanthus.
Common hardy primulas (or polyanthus and related forms) grow 6 to 10 inches high, sending up trusses of yellow and red flowers in early spring. Propagated by division, or by seed sown a year before the plants are wanted. Give them rather moist soil.
The primula of the winter-garden is mostly the P. Sinensis (Chinese Primrose), grown very extensively by florists as a Christmas plant. With the exception of the full double varieties, it is usually grown from seed. There is a popular single form known as P. stellata. The seed of Chinese primulas sown in March or April will make large flowering plants by November or December, if the young plants are shifted to larger pots as needed. The seed should be sown on the flat surface of the soil, composed of equal parts loam, leafmold, and sand. The seed should be pressed down lightly and the soil watered carefully to prevent the seed from being washed into the soil. Very fine sphagnum moss may be sifted over the seed, or the box set in a moist place, where the soil will remain wet until the seeds germinate. When the plants are large enough, they should be potted separately or pricked out into shallow boxes. Frequent pottings or transplantings should be given until September, when they should be in the pots in which they are to bloom. The two essentials to successful growth through the hot summer are shade and moisture. Height, 6 to 8 inches. Bloom in winter and spring.
At present the "baby Primrose" (Primula Forbesi) is popular. It is treated in essentially the same way as the Sinensis. The obconica (P. obconica) in several forms is a popular florist's plant, but is not much used in window-gardens. The hairs poison the hands of some persons. Culture practically as for P. Sinensis.
All primulas are impatient of a dry atmosphere and fluctuating conditions.
RHODODENDRONS are broad-leaved evergreen shrubs that are admirably adapted to producing strong planting effects. Some of them are hardy in the Northern states.
Rhododendrons require a fibrous or peaty soil and protection from bleak winds and bright suns in summer and winter. A northern or somewhat shady exposure, to break the force of the midday sun, is advisable; but they should not be planted where large trees will sap the fertility and moisture from the ground. They protect each other if grown in masses, and also produce better planting effects.
They require a deep, fibrous earth, and it is supposed that they do not thrive in limestone soils or where wood ashes are freely used. While rhododendrons will sometimes succeed without any special preparation of the ground, it is advisable to take particular pains in this regard. It is well to dig a hole 2 or 3 feet deep, and fill it with earth compounded of leafmold, well-rotted sod, and peat. The moisture supply should be never failing, for they suffer from drought. They should be mulched summer and winter. Plant in spring.
The hardy garden forms are derivatives of Rhododendron Catawbiense, of the southern Appalachian Mountains. The Pontica and other forms are not hardy in the North.
The "great laurel" of the northern United States is Rhododendron maximum. This has been extensively colonized in large grounds by being removed from the wild in carload lots. When the native conditions are imitated, it makes unusually good mass planting. Like all rhododendrons it is impatient of drought, hard soil, and full exposure to midday sun. This species is valued for its foliage and habit more than for its bloom. The wild form of R. Catawbiense is also transferred to grounds in large quantities.
ROSE.—No home property is complete without roses. There are so many kinds and classes that varieties may be found for almost any purpose, from climbing or pillar subjects to highly fragrant teas, great hybrid perpetuals, free-blooming bedders, and good foliage subjects for the shrubbery. There is no flower in the growing of which one so quickly develops the temper and taste of the connoisseur.
Roses are essentially flower-garden subjects rather than lawn subjects, since flowers are their chief beauty. Yet the foliage of many of the highly developed roses is good and attractive when the plants are well grown. To secure the best results with roses, they should be placed in a bed by themselves, where they can be tilled and pruned and well taken care of, as other flower-garden plants are. The ordinary garden roses should rarely be grown in mixed borders of shrubbery. It is usually most satisfactory also to make beds of one variety rather than to mix them with several varieties.
If it is desired to have roses in mixed shrubbery borders, then the single and informal types should be chosen. The best of all these is Rosa rugosa. This has not only attractive flowers through the greater part of the season, but it also has very interesting foliage and a striking habit. The great profusion of bristles and spines gives it an individual and strong character. Even without the flowers, it is valuable to add character and cast to a foliage mass. The foliage is not attacked by insects or fungi, but remains green and glossy throughout the year. The fruit is also very large and showy, and persists on bushes well through the winter. Some of the wild roses are also very excellent for mixing into foliage masses, but, as a rule, their foliage characteristics are rather weak, and they are liable to be attacked by thrips.
There are so many classes of roses that the intending planter is likely to be confused unless he knows what they are. Different classes require different treatment. Some of them, as the teas and hybrid perpetuals (the latter also known as remontants), bloom from new canes; while the rugosa, the Austrian, Harrison's yellow, sweet briers, and some others are bushes and do not renew themselves each year from the crown or bases of the canes.
The outdoor roses may be divided into two great groups so far as their blooming habit is involved:
(1) The continuous or intermittent bloomers, as the hybrid perpetuals (blooming chiefly in June), bourbons, tea, rugosa, the teas and hybrid teas being the most continuous in bloom;
(2)those that bloom once only, in summer, as Austrian, Ayrshire, sweet briers, prairie, Cherokee, Banksian, provence, most moss roses, damask, multiflora, polyantha, and memorial (Wichuraiana). "Perpetual" or recurrent-blooming races have been developed in the Ayrshire, moss, polyantha, and others.
While roses delight in a sunny exposure, nevertheless our dry atmosphere and hot summers are sometimes trying on the flowers, as are severe wintry winds on the plants. While, therefore, it is never advisable to plant roses near large trees, or where they will be overshadowed by buildings or surrounding shrubbery, some shade during the heat of the day will be a benefit. The best position is an eastern or northern slope, and where fences or other objects will break the force of strong winds, in those sections where such prevail.
Roses should be carefully taken up every four or five years, tops and roots cut in, and then reset, either in a new place or in the old, after enriching the soil with a fresh supply of manure, and deeply spading it over. In Holland, roses are allowed to stand about eight years. They are then taken out and their places filled with young plants.
Soil and planting for roses.
The best soil for roses is a deep and rich clay loam. If it is more or less of a fibrous character from the presence of grass roots, as is the case with newly plowed sod ground, so much the better. While such is desirable, any ordinary soil will answer, provided it is well manured. Cow manure is strong and lasting, and has no heating effect. It will cause no damage, even if not rotted. Horse manure, however, should be well rotted before mixing it with the soil. The manure may be mixed in the soil at the rate of one part in four. If well rotted, however, more will not do any damage, as the soil can scarcely be made too rich, especially for the everblooming (hybrid tea) roses. Care should be taken to mix the manure thoroughly with the earth, and not to plant the roses against the manure.
In planting, care must be taken to avoid exposing the roots to the drying of sun and air. If dormant field-grown plants have been purchased, all broken and bruised roots will need to be cut off smoothly and squarely. The tops also will need cutting back. The cut should always be made just above a bud, preferably on the outer side of the cane. Strong-growing sorts may be cut back one-fourth or one-half, according as they have good or bad roots. Weaker-growing kinds, as most of the everblooming roses, should be cut back-most severely. In both cases it is well to remove the weak growth first. Plants set out from pots will usually not need cutting back.
Hardy roses, especially the strong field-grown plants, should be set in the early fall if practicable. It is desirable to get them out just as soon as they have shed their foliage. If not then, they may be planted in the early spring. At that season it is advisable to plant them as early as the ground is dry enough, and before the buds have started to grow. Dormant pot-plants may also be set out early, but they should be perfectly inactive. Setting them out early in this condition is preferable to waiting till they are in foliage and full bloom, as is so often required by buyers. Growing pot-plants may be planted any time in spring after danger of frost is past, or even during the summer, if they are watered and shaded for a few days.
Open-ground plants should be set about as deep as they stood previously, excepting budded or grafted plants, which should be set so that the union of the stock and graft will be 2 to 4 inches below the surface of the ground. Plants from pots may also be set an inch deeper than they stood in the pots. The soil should be in a friable condition. Roses should have the soil compact immediately about their roots; but we should distinguish between planting roses and setting fence posts. The dryer the soil the more firmly it may be pressed.
As a general statement, it may be said that roses on their own roots will prove more satisfactory for the general run of planters than budded stock. On own-rooted stock, the suckers or shoots from below the surface of the soil will be of the same kind, whereas with budded roses there is danger of the stock (usually Manetti or dog rose) starting into growth and, not being discovered, outgrowing the bud, taking possession, and finally killing out the weaker growth. Still, if the plants are set deep enough to prevent adventitious buds of the stock from starting and the grower is alert, this difficulty is reduced to a minimum. There is no question but that finer roses may be grown than from plants on their own roots, withstanding the heat of the American summer, if the grower takes the proper precautions.
Pruning roses.
In pruning roses, determine whether they bloom on canes arising each year from the ground or near the ground, or whether they make perennial tops; also form a clear idea whether an abundance of flowers is wanted for garden effects, or whether large specimen blooms are desired.
If one is pruning the hybrid perpetual or remontant roses (which are now the common garden roses), he cuts back all very vigorous canes perhaps one-half their length immediately after the June bloom is past in order to produce new, strong shoots for fall flowering, and also to make good bottoms for the next year's bloom. Very severe summer pruning, however, is likely to produce too much leafy growth. In the fall, all canes may be shortened to 3 feet, four or five of the best canes being left to each plant. In spring, these canes are again cut back to fresh wood, leaving perhaps four or five good buds on each cane; from these buds the flowering canes of the year are to come. If it is desired to secure fewer blooms, but of the best size and quality, fewer canes may be left and only two or three new shoots be allowed to spring from each one the next spring.
The rule in trimming all cane-bearing roses is, cut back weak growing kinds severely; strong growers moderately.
Climbing and pillar roses need only the weak branches and the tips shortened in. Other hardy kinds will usually need cutting back about one-fourth or one-third, according to the vigor of the branches, either in the spring or fall.
The everblooming or hybrid tea roses will need to have all dead wood removed at the time of uncovering them in spring. Some pruning during the summer is also useful in encouraging growth and flowers. The stronger branches that have flowered may be cut back one-half or more.
The sweet briers, Austrian and rugosas may be kept in bush form; but the trunks may be cut out at the ground every two or three years, new shoots having been allowed to come up in the meantime. All rampant growths should be cut back or taken out.
Insects and diseases of roses.
Most of the summer insects that trouble the rose are best treated by a forceful spray of clear water. This should be done early in the day and again at evening. Those having city water or good spray pumps will find this an easy method of keeping rose pests in check. Those without these facilities may use whale-oil soap, fir-tree oil, good soap suds, the tobacco preparations, or Persian insect powder.
The rose-bug or chafer should be hand-picked or knocked off early in the morning into a pan of coal oil. The leaf-roller must be crushed.
The mildews are controlled by the various sulfur sprays.
Winter protection of roses.
All garden roses should be well mulched with leaves or coarse manure in the fall. Mounding earth about the root also affords excellent protection. Bending over the tops and covering with grass or evergreen boughs is also to be recommended for such kinds as are suspected to be injured by winter; the boughs are preferable because they do not attract mice.
North of the Ohio River all the everblooming roses, even if they will endure the winter unprotected, will be better for protection. This may be slight southward, but should be thorough northward. The soil, location, and surroundings often determine the extent of protection. If the situation is not so favorable, more protection will be necessary. Along the Ohio, a heap of stable manure, or light soil that does not become packed and water-logged, placed about the base of the plants, will carry over many of the tea roses. The tops are killed back; but the plants sprout from the base of the old branches in the spring. Bon Silene, Etoile de Lyon, Perle des Jardins, Mme. Camille, and others are readily wintered there in this way.
About Chicago (American Florist, x., No. 358, p. 929, 1895) beds have been successfully protected by bending down the tops, fastening them, and then placing over and among the plants a layer of dead leaves to the depth of a foot. The leaves must be dry, and the soil also, before applying them; this is very essential. After the leaves, a layer of lawn-clippings, highest at the middle, and 4 or 5 inches thick, placed over the leaves, holds them in place and sheds water. This protection carries over the hardiest sorts of everblooming roses, including the teas. The tops are killed back when not bent down, but this protection saves the roots and crowns; when bent down, the tops went through without damage. Even the climbing rose Gloire de Dijon was carried through the winter of 1894-1895 at Chicago without the slightest injury to the branches.
Strong plants of the everblooming or hybrid tea roses can now be had at very reasonable rates, and rather than go to the trouble of protecting them in the fall, many persons buy such as they need for bedding purposes each spring. If the soil of the beds is well enriched, the plants make a rapid and luxuriant growth, blooming freely throughout the summer.
If one desires to go to the trouble, he may protect these and also the tea roses even in the northern states by mounding earth about the plants and then building a little shed or house about them (or inverting a large box over them) and packing about the plants with leaves or straw. Some persons make boxes that can be knocked down in the spring and stored. The roof should shed water. This method is better than tying the plants up in straw and burlaps. Some of the hybrid teas do not need so much protection as this, even in central New York.
Varieties of roses.
The selection of kinds should be made in reference to the locality and purpose for which the roses are wanted. For bedding roses, those that are of free-blooming habit, even though the individual flowers are not large, are the ones that should be chosen. For permanent beds, the so-called hybrid perpetual or remontant roses, blooming principally in June, will be found to be hardy at the North.—But if one can give them proper protection during the winter, then the Bengal, tea, bourbon, and hybrid teas or everblooming roses, may be selected.
In sections where the temperature does not fall below 20 deg. above zero, any of the monthly roses will live without protection. At the South the remontants and other deciduous roses do not do as well as farther North. The tender climbers—Noisettes, climbing teas, bengals, and others—are excellent for pillars, arbors, and verandas at the South, but are fit only for the conservatory in those parts of the country where there is severe freezing. For the open air at the North we have to depend for climbing roses mainly on the prairie climbers, and the ramblers (polyanthas), with their recent pink and white varieties. The trailing Rosa Wichuraiana is also a useful addition as an excellent hardy rose for banks.
For the northern states a choice small list is as follows: hybrid perpetuals, Mrs. John Laing, Wilder, Ulrich Brunner, Frau Karl Druschki, Paul Neyron; dwarf polyanthas, Clothilde Soupert, Madame Norbert Levavasseur (Baby Rambler), Mlle. Cecile Brunner; hybrid teas, Grus an Teplitz, La France, Caroline Testout, Kaiserin Victoria, Killarney; teas, Pink Maman Cochet, White Maman Cochet.
The following classified lists embrace some of the varieties of recognized merit for various purposes. There are many others, but it is desirable to limit the list to a few good kinds. The intending planter should consult recent catalogues.
Free-blooming monthly roses for bedding.—These are recommended not for the individual beauty of the flower—although some are very fine—but because of their suitability for the purpose indicated. If to be carried over winter in the open ground, they need to be protected north of Washington. In beds, pegging down the branches will be found desirable. Those marked (A) have proved hardy in southern Indiana without protection, although they are more satisfactory with it. (The name of the class to which the variety belongs is indicated by the initial letter or letters of the class name: C., China; T., Tea; H.T., Hybrid Tea; B., Bourbon; Pol., Polyantha; N., Noisette; H.P., Hybrid Perpetual; Pr., Prairie Climber):—
Red—Sanguinea, C. Agrippina, C. Marion Dingee, T. (A)Meteor, H.T.

Yellow—(A)Isabella Sprunt, T. Mosella (Yellow Soupert), Pol. La Pactole, T. Marie van Houtte, T.
Free-blooming monthly roses for summer cutting and beds.—These are somewhat less desirable for purely bedding purposes than the preceding; but they afford finer flowers and are useful for their fine buds. Those marked (A) are hardy in southern Indiana without protection:—
Red—(A)Meteor. (A)Dinsmore, H.P. (A)Pierre Guillot, H.T. Papa Gontier, T.
Light Pink—(A)La France, H.T. Countess de Labarthe, T. (A)Appoline, B.

Yellow—Perle des Jardins, T. Mme. Welch, T. Sunset, T. Marie van Houtte, T.
Hybrid perpetual, or remontant, roses,—These do not flower as freely as the groups previously mentioned; but the individual flowers are very large and unequaled by any other roses. They flower chiefly in June. Those named are among the finest sorts, and some of them flower more or less continuously:—
Red—Alfred Colomb. Earl of Dufferin. Glorie de Margottin. Anna de Diesbach. Ulrich Brunner.
Pink—Mrs. John Laing. Paul Neyron. Queen of Queens. Magna Charta. Baroness Rothschild.
White—Margaret Dickson. Merveille de Lyon.
Hardy climbing, or pillar roses.—These bloom but once during the season. They come after the June roses, however,—a good season—and at that time are masses of flowers. They require only slight pruning.
White—Baltimore Belle, Pr. Washington, N. Rosa Wichuraiana (trailing).
Pink—Queen of the Prairies, Pr. Tennessee Belle, Pr. Climbing Jules Margotten, H.P.
Crimson—Crimson Rambler, Pol.
Yellow—Yellow Rambler, Pol.
Tender climbing, or pillar roses. For conservatories, and the South as far north as Tennessee.—Those marked with (A)are half-hardy north of the Ohio River, or about as hardy as the hybrid teas. These need no pruning except a slight shortening-in of the shoots and a thinning out of the weak growth.
Yellow—Marechal Niel, N. Solfaterre, N. (A)Gloire de Dijon, T. Yellow Banksia (Banksiana).
White—(A)Aimee Vibert, N. Bennett's Seedling (Ayrshire). White Banksia (Banksiana).
Red—(A)Reine Marie Henriette, T. James Sprunt, C.
Roses in winter (by C.E. Hunn).
Although the growing of roses under glass must be left chiefly to florists, advice may be useful to those who have conservatories:—
When growing forcing roses for winter flowers, florists usually provide raised beds, in the best-lighted houses they have. The bottom of the bed or bench is left with cracks between the boards for drainage; the cracks are covered with inverted strips of sod, and the bench is then covered with 4 or 5 inches of fresh, fibrous loam. This is made from rotted sods, with decayed manure incorporated at the rate of about one part in four. Sod from any drained pasture-land makes good soil. The plants are set on the bed in the spring or early summer, from 12 to 18 inches apart, and are grown there all summer.
During the winter they are kept at a temperature of 58 deg. to 60 deg. at night, and from 5 deg. to 10 deg. warmer during the day. The heating pipes are often run under the benches, not because the rose likes bottom heat, but to economize space and to assist in drying out the beds in case of their becoming too wet. The greatest care is required in watering, in guarding the temperature, and in ventilation. Draughts result in checks to the growth and in mildewed foliage.
Dryness of the air, especially from fire heat, is followed by the appearance of the minute red spider on the leaves. The aphis, or green plant louse, appears under all conditions, and must be kept down by the use of some of the tobacco preparations (several of which are on the market).
For the red spider, the chief means of control is syringing with either clear or soapy water. If the plants are intelligently ventilated and given, at all times, as much fresh air as possible, the red spider is less likely to appear. For mildew, which is easily recognized by its white, powdery appearance on the foliage, accompanied with more or less distortion of the leaves, the remedy is sulfur in some form or other. The flowers of sulfur may be dusted thinly over the foliage; enough merely slightly to whiten the foliage is sufficient. It may be dusted on from the hand in a broadcast way, or applied with a powder-bellows, which is a better and less wasteful method. Again, a paint composed of sulfur and linseed oil may be applied to a part of one of the steam or hot-water heating pipes. The fumes arising from this are not agreeable to breathe, but fatal to mildew. Again, a little sulfur may be sprinkled here and there on the cooler parts of the greenhouse flue. Under no circumstances, however, ignite any sulfur in a greenhouse. The vapor of burning sulfur is death to plants.
Propagation of house roses.—The writer has known women who could root roses with the greatest ease. They would simply break off a branch of the rose, insert it in the flower-bed, cover it with a bell-jar, and in a few weeks they would have a strong plant. Again they would resort to layering; in which case a branch, notched halfway through on the lower side, was bent to the ground and pegged down so that the notched part was covered with a few inches of soil. The layered spot was watered from time to time. After three or four weeks roots were sent forth from the notch and the branch or buds began to grow, when it was known that the layer had formed roots.
Several years ago a friend took a cheese-box, filled it with sharp sand to the brim, supported it in a tub of water so that the lower half-inch of the box was immersed. The sand was packed down, sprinkled, and single-joint rose cuttings, with a bud and a leaf near the top, were inserted almost their whole length in the sand. This was in July, a hot month, when it is usually difficult to root any kind of cutting; moreover, the box stood on a southern slope, facing the hot sun, without a particle of shade. The only attention given the box was to keep the water high enough in the tub to touch the bottom of the cheese-box. In about three weeks he took out three or four dozen of as nicely rooted cuttings as could have been grown in a greenhouse.
The "saucer system," in which cuttings are inserted in wet sand contained in a saucer an inch or two deep, to be exposed at all times to the full sunshine, is of a similar nature. The essentials are, to give the cuttings the "full sun" and to keep the sand saturated with water.
Whatever method is used, if cuttings are to be transplanted after rooting, it is important to pot them off in small pots as soon as they have a cluster of roots one-half inch or an inch long. Leaving them too long in the sand weakens the cutting.

SMILAX of the florists is closely allied to asparagus (it is Asparagus medeoloides of the botanists). While it cannot be recommended for house culture, the ease with which it may be grown and the uses to which the festoons of leaves may be put entitle it to a place in the conservatory or greenhouse.
Seed sown in pots or boxes in January or February, the plants shifted as needed until planted on the bench in August, will grow fine strings of green by the holidays. The temperature should be rather high. The plants should be set on low benches, giving as much room as possible overhead. Green-colored strings should be used for the vines to climb on, the vines frequently syringed to keep down the red spider, which is very destructive to this plant, and liquid manure given as the vines grow. The soil should contain a good proportion of sand and be enriched with well-rotted manure.
After the first strings are cut, a second growth fully as good as the first may be had by cleaning up the plants and top-dressing the soil with rotted manure. Sometimes the old roots are kept three or four years. Slightly shading the house through August will add to the color of the leaves. The odor from a vine of smilax thickly covered with the small flowers is very agreeable.
STOCKS.—The Ten-weeks and the biennial or Brompton stocks (species of Matthiola) are found in nearly all old-fashioned gardens. Most gardens are thought to be incomplete without them, and the use of the biennial flowering species as house-plants is increasing.
The Ten-weeks stock is usually grown from seed sown in hotbeds or boxes in March. The seedlings are transplanted several times previous to being planted out in early May. At each transplanting the soil should be made a little richer. The double flowers will be more numerous when the soil is rich.
The biennial species (or Brompton stocks) should be sown the season previous to that in which flowers are wanted, the plants wintered over in a cool house, and grown in the following spring. They may be planted out through the summer and lifted into pots in August or September for winter flowering. These may be increased by cuttings taken from the side shoots; but the sowing of seed is a surer method, and unless an extra fine variety is to be saved, it would be the best one to pursue. Height, 10 to 15 inches.
SWEET PEA.—A hardy, tendril-climbing annual, universally prized as an outdoor garden plant; also forced to some extent by florists. On any occasion the sweet pea is in place. A bouquet of shaded colors, with a few sprays of galium or the perennial gypsophila, makes one of the choicest of table decorations.
Deep, mellow soil, early planting, and heavy mulching suit them admirably. It is easy to make soils too rich in nitrogen for sweet peas; in such case, they will run to vine at the expense of flowers.
Sow the seeds as soon as the ground is fit to work in the spring, making a drill 5 inches deep. Sow thickly and cover with 2 inches of earth. When the plants have made 2 or 3 inches' growth above the earth, fill the drill nearly full, leaving a slight depression in which water may be caught. After the soil is thoroughly soaked with water, a good mulch will hold the moisture. To have the ground ready in early spring, it is a good plan to trench the ground in the fall. The top of the soil then dries out very quickly in spring and is left in good physical condition.
In the middle and southern states the seed may be planted in fall, particularly in lighter soils.
Frequent syringing with clear water will keep off the red spider that often destroys the foliage, and attention to picking the seed pods will lengthen the season of bloom. If the finest flowers are wanted, do not let the plants stand less than 8 to 12 inches apart.
A succession of sowings may be made at intervals through May and June, and a fair fall crop secured if care is taken to water and mulch; but the best results will be secured with the very early planting. When the plants are watered, apply enough to soak the soil, and do not water frequently.
SWAINSONA.—This plant has been called the winter sweet pea, but the flowers are not fragrant. It makes a very desirable house plant, blooming through the late winter and early spring months. The blossoms, which resemble those of the pea, are borne in long racemes. The foliage is finely cut, resembling small locust leaves, and adds to the beauty of the plant, the whole effect being exceedingly graceful. Swainsona may be grown from seed or cuttings. Cuttings taken in late winter should make blooming plants in summer; these plants may be used for winter bloom, but it is better to raise new plants. Some gardeners cut back old plants to secure new blooming wood; this is desirable if the plants grow more or less permanently in the greenhouse border, but for pots new plants should be grown.
The common swainsona is white-flowered; but there is a good rose-colored variety.
TUBEROSE (properly tuber-ose, not tube-rose, from its specific name, Polianthes tuberosa).—This plant, with its tall spikes of waxen and fragrant white flowers, is well known in the middle latitudes, but usually requires more heat and a longer season than are commonly present in the most northern states.
The tuberose is a strong feeder, and loves warmth, plenty of water while growing, and a deep, rich, and well-drained soil. The bulbs may be set in the garden or border the last of May or in June, covering them about 1 inch deep. Preparatory to planting, the old dead roots at the base of the bulb should be cut away and the pips or young bulbs about the sides removed. After keeping them till their scars are dried over, these pips may be planted 5 or 6 inches apart in drills, and with good soil and cultivation they will make blooming bulbs for the following year.
Before planting the large bulbs, it may be well to examine the points, to determine whether they are likely to bloom. The tuberose blooms but once. If there is a hard, woody piece of old stem in the midst of the dry scales at the apex of the bulb, it has bloomed, and is of no value except for producing pips. Likewise if, instead of a solid core, there is a brownish, dry cavity extending from the tip down into the middle of the bulb, the heart has rotted or dried up, and the bulb is worthless as far as blooming is concerned.
Bulbs of blooming size set in the border in June flower toward the close of September. They may be made to flower three or four weeks sooner by starting them early in some warm place, where they may be given a temperature of about 60 deg. to 70 deg.. Prepare the bulbs as above, and place them with their tips just above the surface in about 3-or 4-inch pots, in light sandy soil. Water them thoroughly, afterwards sparingly, till the leaves have made considerable growth. These plants may be turned out into the open ground the last of May or in June, and will probably flower in early September.
In the northern states, if planted in the border they will not start into growth until the ground has become thoroughly warm,—usually after the middle of June,—making the season before frost too short for their perfect growth and flower. If any danger of fall frost is feared, they may be lifted into pots or boxes and taken into the house, when they will bloom without a check. As with other bulbs, a sandy soil will suit.
Just before frost dig up the bulbs, cut off the tops to within 2 inches of the apex of the bulb. They may then be placed in shallow boxes and left out in the sun and air for a week or more, to cure. Each evening, if the nights are cold, they should be removed to some room where the temperature will not fall below 40 deg.. When the outer scales have become dry, the remaining soil may be shaken off and the bulbs stored away in shallow boxes for the winter. They keep best in a temperature of 45 deg. to 50 deg.. It should never fall below 40 deg..
The Dwarf Pearl, originating in 1870, has long been popular, and is still so with many. But others have come to prefer the old, tall kind, the flowers of which, even if not so large, are perfect in form and seem to open better.
TULIPS are undoubtedly the most prized of all early spring bulbs. They are hardy and easy to grow. They also bloom well in winter in a sunny climate. The garden bed will last several years if well cared for, but most satisfactory bloom is secured if the old bulbs are taken up every two or three years and replanted, all the inferior ones being cast aside. When the stock begins to run out, buy anew. The old stock, if not entirely spent, may be planted in the shrubbery or perennial borders.
September is the best time for planting tulips, but as the beds are usually occupied at this time, planting is commonly postponed till October of November. For garden culture the single early tulips are the best. There are excellent early double-flowered varieties. Some prefer the double, as their flowers last longer. Late tulips are gorgeous, but occupy the beds too long in the spring. While tulips are hardy, they are benefited by a winter mulch.
In working out design patterns, the utmost care should be used to have the lines and curves uniform, which is only to be secured by marking out the design, and careful planting. Formal planting is, however, by no means necessary for pleasing effects. Borders, lines, and masses of single colors, or groups of mixed colors which harmonize, are always in order and pleasing. Clear colors are preferable to neutral tints. As varieties vary in height and season of blooming, only named varieties should be ordered if uniform bedding effects are desired. See pp. 286 and 345; Fig. 255.
VIOLET.—While the culture of violets as house-plants rarely proves successful, there is no reason why a good supply may not be had elsewhere through the greater part of the winter and the spring months.
A sheltered location being selected, young plants from runners may be set in August or September. Have the ground fertile and well drained. These plants will make fine crowns by December, and often will bloom before weather sufficiently cold to freeze them.
To have flowers through the winter, it will be necessary to afford some protection. This may best be accomplished by building a frame of boards large enough to cover the plants, making the frame in the same way as for a hotbed, 4 to 6 inches higher at the back than the front. Cover the frame with sash or boards, and as the weather becomes severe, mats or straw should be placed over and around the frame to protect the plants from freezing. Whenever the weather will permit, the covering should be removed and air admitted, but no harm will come if the frames are not disturbed for several weeks. Much sunlight and a high temperature through the middle of winter are to be avoided, for if the plants are stimulated, a shorter period of bloom will result. In April the frame may be removed, the plants yielding the later part of the crop without protection.
Violets belong with the "cool" plants of florists. When well hardened off, considerable frost does not harm them. They should always be kept stocky. Start a new lot from runner-plants each year. They thrive in a temperature of 55 deg. to 65 deg.. Pages 190, 206.
WAX-PLANT.—The wax-plant, or hoya, is one of the commonest of window-garden plants, and yet it is one that house-gardeners usually have difficulty in flowering. However, it is one of the easiest plants to manage if a person understands its nature.
It is naturally a summer-blooming plant, and should rest in winter. In the winter, keep it just alive in a cool and rather dry place. If the temperature does not go above 50 deg. Fahr., so much the better; neither should it go much lower. In late winter or spring, the plant is brought out to warm temperature, given water, and started into growth. The old flower-stems should not be cut off, since new flowers come from them as well as from the new wood. When it is brought out to be started into growth, it may be repotted, sometimes into a size larger pot, but always with more or less fresh earth. The plant should increase in value each year. In conservatories, it is sometimes planted out in the ground and allowed to run over a wall, in which case it will reach a height of many feet.
CHAPTER IX
THE GROWING OF THE FRUIT PLANTS
Fruits should be counted a regular part of the home premises. There are few residence plots so small that fruits of some kind cannot be grown. If there is no opportunity for planting the orchard fruits by themselves at regular intervals, there are still boundaries to the place, and along these boundaries and scattered in the border masses, apples, pears, and other fruits may be planted.
It is not to be expected that fruits will thrive as well in these places as in well-tilled orchards, but something can be done, and the results are often very satisfactory. Along a back fence or walk, one may plant a row or two of currants, gooseberries, or blackberries, or he may make a trellis of grapes. If there are no trees near the front or back of the border, the fruit plants may be placed close together in the row and the greatest development of the tops may be allowed to take place laterally. If one has a back yard fifty feet on a side, there will be opportunity, in three borders, for six to eight fruit trees, and bush-fruits between, without encroaching greatly on the lawn. In such cases, the trees are planted just inside the boundary line.
A suggestion for the arrangement of a fruit garden of one acre is given in Fig. 270. Such a plan allows of continuous cultivation in one direction and facilitates spraying, pruning, and harvesting; and the intermediate spaces may be used for the growing of annual crops, at least for a few years.
Dwarf fruit-trees.
For very small areas, and for the growing of the finest dessert fruits, dwarf trees may be grown of apples and pears. The apple is dwarfed when it is worked on certain small and slow-growing types of apple trees, as the paradise and doucin stocks. The paradise is the better, if one desires a very small and productive tree or bush. The doucin makes only a half-dwarf.
The pear is dwarfed when it is grown on the root of quince. Dwarf pears may be planted as close as ten feet apart each way, although more room should be given them if possible. Paradise dwarfs (apples) may be planted eight or ten feet each way, and doucin twice that distance. All dwarfs should be kept small by vigorous annual heading-in. If the tree is making good growth, say one to three feet, a half to two-thirds of the growth may be taken off in winter. A dwarf apple or pear tree should be kept within a height of twelve or fifteen feet, and it should not attain this stature in less than ten or twelve years. A dwarf apple tree, in full bearing, should average from two pecks to a bushel of first quality apples, and a dwarf pear should do somewhat more than this.
If one grows dwarf fruit trees, he should expect to give them extra attention in pruning and cultivating. Only in very exceptional instances can the dwarf fruits be expected to equal the free-growing standards in commercial results. This is particularly true of dwarf apples, which are practically home-garden plants in this country. This being the case, only the choice dessert fruits should be attempted on paradise and doucin roots. For home gardens the paradise will probably give more satisfaction than the doucin.
If the tree is taken young, it may be trained along a wall or on an espalier trellis; and in such conditions the fruits should be of extra quality if the varieties are choice. Plate XXII shows the training of a dwarf pear on a wall. This tree has been many years in good bearing. In most parts of the country a southern wall exposure is likely to force the bloom so early as to invite danger from spring frosts.
Age and size of trees.
For ordinary planting, it is desirable to choose trees two years from bud or graft, except in case of the peach, which should be one year old. Many growers find strong one-year trees preferable. A good size is about five-eighths of an inch in diameter just above the collar, and five feet in height, and if they have been well grown, trees of this size will give as good results as those seven-eighths of an inch, or more, in diameter, and six or seven feet high. Buy first-class trees of reliable dealers. It rarely pays to try to save a few cents on a tree, for quality is likely to be sacrificed.
If properly packed, trees can be shipped long distances and may do as well as those grown in a home nursery, but it will generally be best to secure the trees as near home as possible, provided the quality of the trees and the price are satisfactory. When a large number is to be purchased, it will be better to send the order direct to some reliable nursery, or to select the trees in person, than to rely on tree peddlers.
Pruning.
Having planted the trees, they should be carefully pruned. As a rule, trees with low heads are desirable. Peaches and dwarf pears should have the lower branches from 12 to 24 inches above ground, and sweet cherries and standard pears generally not over 30 inches; plums, sour cherries, and apples may be somewhat higher, but if properly handled, when started 3 feet from the ground, the tops will not be in the way of the cultivation of the orchard.
For all except the peach in the northern states, a pyramidal form will be desirable. To secure this, four or five side branches with three or four buds each, should be allowed to grow and the center shoot should be cut off at a height of 10 to 12 inches. After growth has started, the trees should be occasionally examined and all surplus shoots removed, thus throwing the full vigor of the plant into those that remain. As a rule three or four shoots on each branch may be left to advantage. The following spring the shoots should be cut back one-half and about half of the branches removed. Care should be taken to avoid crotches, and if any of the branches cross, so that they are likely to rub, one or the other should be cut out. This cutting-back and trimming-out should be continued for two or three years, and in the case of dwarf pear trees regular heading-back each year should be continued. Although an occasional heading-back will be of advantage to the trees, apple, plum, and cherry trees that have been properly pruned while young will not require so much attention after they come into bearing.
Heavy pruning of the top tends to the production of wood; therefore the severe pruning of orchard trees, following three or four years of neglect, sets the trees into heavy wood-bearing, and makes them more vigorous. Such treatment generally tends away from fruit-bearing. This heavy pruning is usually necessary in neglected orchards, however, to bring trees back into shape and to revitalize them; but the best pruning-treatment of an orchard is to prune it a little every year. It should be so pruned that the tops of the trees will be open, that no two limbs will interfere with each other, and so that the fruit itself will not be so abundant as to overload the tree.
In general, it is best to prune orchard trees late in winter or early in spring. It is sometimes better, however, to leave peaches and other tender fruits until after the buds have swollen, or even after the flowers have fallen, in order that one may determine how much they have been injured by the winter. Grape vines should be pruned in winter or not later (in New York) than the first of March. If pruned later than this, they may bleed. The above remarks will apply to other trees as well as to fruits.
Thinning the fruit.
If the best size and quality of fruit are desired, care must be taken to see that the plant does not overbear.
Thinning of fruit has four general uses: to cause the remaining fruit to grow larger; to increase the chances of annual crops; to save the vitality of the tree; to enable one to combat insects and diseases by destroying the injured fruit.
The thinning is nearly always performed soon after the fruit is thoroughly set. It is then possible to determine which of the fruits are likely to persist. Peaches are usually thinned when they are the size of one's thumb. If thinned before this time, they are so small that it is difficult to pick them off; and it is not so easy to see the work of the curculio and thereby to select the injured fruits. Similar remarks apply to other fruits. The general tendency is, even with those who thin their fruits, not to thin enough. It is usually safer to take off what would seem to be too many than not to take off enough. The remaining specimens are better. Varieties that tend to overbear profit very greatly by thinning. This is notably the case with many Japanese plums, which, if not thinned, are very inferior.
Thinning may also be accomplished by pruning. Cutting off the fruit-buds will have the effect of removing the fruit. In the case of tender fruits, as peaches, however, it may not be advisable to thin very heavily by means of pruning, since the fruit may be still further thinned by the remaining days of winter, by late spring frost, or by the leaf-curl or other disease. However, the proper pruning of a peach tree in winter is, in part, a thinning of the fruit. The peach is borne on the wood of the previous season's growth. The best fruits are to be expected the strongest and heaviest growth. It is the practice of peach-growers to remove all the weak and immature wood from the inside of the tree. This has the effect of thinning out the inferior fruit and allowing the energy of the tree to be expended on the remainder.
Apples are rarely thinned; but, in many cases, thinning can be done with profit.
Washing and scrubbing the trees.
The washing of orchard trees is an old practice. It usually results in making a tree more vigorous. One reason is that it destroys insects and fungi that lodge underneath the bark; but probably the chief reason is that it softens the bark and allows the trunk to expand. It is possible, also, that the potash from the soap or lye eventually passes into the ground and affords some plant-food. Trees are ordinarily washed with soap suds or with a lye solution. The material is usually applied with an old broom or a stiff brush. The scrubbing of the tree is perhaps nearly or quite as beneficial as the application of the wash itself.
It is customary to wash trees late in spring or early in summer, and again in the fall, with the idea that such washing destroys the eggs and the young of borers. It no doubt will destroy borers if they are just getting a start, but it will not keep away the insects that lay the eggs, and will not destroy the borers that have found their way beneath the bark. It is perhaps quite as well to wash the trees very early in the spring, when they are starting into growth.
It is an old practice to wash trees with strong lye when they are affected with the oyster-shell bark louse. The modern method of treating these pests, however, is to spray with some kerosene or oil compound when the young growth is starting, for at that time the young insects are migrating to the new wood and they are very easily destroyed.
The whitewashing of the trunks of trees tends also to relieve them of insects and fungi; and it is probable that in hot and dry regions the white covering affords protection from climate.
Gathering and keeping fruit.
Nearly all fruits should be gathered as soon as they will readily part from the stems on which they are borne. With many perishable fruits the proper time for gathering will be determined largely by the distance they are to be shipped. With the exception of winter varieties of apples and pears and a few kinds of grapes, it is best to dispose of fruit soon after it is gathered, unless it is kept for family use.
If for winter use, the fruit should at once be placed in the cellar or fruit house in which it is to be stored, and there kept as near the freezing point as possible. There will be less danger of shriveling if the fruit is placed at once in closed barrels or other tight packages, but if proper ventilation is provided, it may be kept in bins with little loss. Even though no ice is used, it will be possible to maintain a fairly low temperature by opening the windows at night when the outside atmosphere is colder than that inside the building, and closing them during the day as the outer air becomes warmer.
Fruit should be handled with great care at all times, for if the cells become broken by rough handling, the keeping qualities will be greatly injured. The illustrations (Figs. 187-189) show three types of fruit storage houses.
Apples and winter pears may be packed in sand or leaves in the cellar (in boxes) and thereby be kept from shriveling.
ALMOND.—The almond tree is seldom seen in the eastern states, but now and then one will be found in a yard and not bearing. The failure to bear may be due to frost injury or lack of pollination.
The almond is about as hardy as the peach, but it blooms so early in the spring that it is little grown east of the Pacific slope. It is an interesting ornamental tree, and its early bloom is a merit when the fruit is not desired. The almonds commonly sold by nurserymen in the east are hard-shell varieties, and the nuts are not good enough for commerce. The almond fruit is a drupe, like the peach, but the flesh is thin and hard and the pit is the "almond" of commerce. Culture as for peach.
The "flowering almonds" are bushes of different species from the fruit-bearing tree. They are usually grafted on plum, and the stock is likely to throw up suckers and cause trouble.
APPLES thrive over a wider range of territory and under more varied conditions than any other tree fruit. This means that they are easy to grow. In fact they are so easy to grow that they are usually neglected.
Apples do best on a strong, sandy loam soil, or a light clay loam. While a soil very rich in organic matter is not desirable, good results cannot be secured unless it contains a fair amount of vegetable matter. A clover sod is particularly desirable for this as well as for other fruits.
For a commercial orchard, most varieties should be from 35 to 40 feet apart; but the slow-growing and long-lived sorts may be at 40 feet, and, halfway between in both directions, some of the short-lived, early-bearing varieties may be placed, to be removed after they begin to crowd. In home grounds the trees may be placed somewhat closer than 35 to 40 feet, especially if they are planted on the boundaries, so that the limbs may project freely in one direction.
It is ordinarily advisable, especially in the humid climates east of the Great Lakes, to have the body of the tree 3-1/2 to 4-1/2 feet long. The limbs should be trimmed up to this point when the tree is set. From three to five main branches may be left to form the framework of the top. These should be shortened back one-fourth or one-half when the tree is set. (Figs. 142-145) Subsequent pruning should keep the top of the tree open and maintain it in more or less symmetrical form. West of the Great Lakes, particularly on the plains and in the semi-arid regions, the top may be started much nearer the ground.
In orchard conditions, the trees should be kept in clean culture, especially for the first few years; but this is not always possible in home yards. In lieu of tillage, the sward may be mulched each fall with stable manure, and commercial fertilizer may be applied each fall or spring. If fruit is wanted rather than foliage and shade, care should be taken not to make ground too rich, but to keep it in such condition that the tree is making a fairly vigorous growth, with good strong foliage, but is not overgrowing. An apple tree in full bearing is usually in good condition if the twigs grow 10 to 18 inches each season.
Apple trees should begin to bear when three to five years planted, and at ten years should be bearing good crops. With good treatment, they should continue to bear for thirty or more years in the northeastern states.
Insects and diseases of the apple.
Among the insects most commonly found on the apple tree are the codlin-moth, canker-worm, and tent-caterpillar. The codlin-moth lays its egg on the fruit soon after the blossoms fall, and the larvae, on hatching, eat their way inside. A thorough spraying of the trees with arsenites within a week after the blossoms fall will do much toward destroying them; and a second application, in about three weeks, will be essential. The canker-worm (Fig. 217) and tent-caterpillars feed on the leaves, and can also be destroyed by means of arsenites. To be effective against the former, however, the applications must be made soon after they hatch, and very thoroughly.
A close watch should be kept for borers. Whenever the bark appears to be dead or sunken in patches, remove it and search for the cause. A borer will usually be found underneath the bark. About the base of the tree the most serious injury occurs from borers, since the insect which enters there bores into the hard wood. His presence can be determined by the chips that are cast from his burrows. If the trees are well cultivated and in a thrifty growing condition, the injury will be greatly reduced. It will be well to wash the trunks and larger branches with soft soap, thinned with water so that it can be applied with a brush or broom, during the spring. The addition of an ounce of Paris green in each five gallons of the wash will be of value. The only real remedy, however, is to dig the borers out.
The most troublesome disease of the apple is the apple-scab, which disfigures the fruit as well as lessens its size. It also often does much harm to the foliage, and thus checks the growth of the trees (Fig. 214). The Baldwin, Fameuse, Northern Spy and Red Canada are particularly subject to this disease, and it is much more troublesome in moist seasons than when the weather is dry. The use of fungicides will do much to lessen the injury from this disease.
Varieties of apple.
The selection of varieties of apples for home use is, to a large extent, a personal matter; and no one may say what to plant. A variety that is successfully grown in one section may prove disappointing in another. One should study the locality in which he wishes to plant and choose those varieties which are the most successfully grown there,—choosing from amongst the successful kinds those which he likes best and which seem best to meet the purposes for which he is to grow them.
For the northern and eastern states, the following varieties will generally be found valuable:—
[The varieties marked with (A) are particularly valuable for market purposes as well as for home use; the others are chiefly desirable for home use.]
Early.—Yellow Transparent, Early Harvest, Early Strawberry, Primate, Dyer, Summer Rose, Early Joe, Red Astrachan, Golden Sweet, Oldenburg,(A) Summer Pearmain, Williams (Favorite), Chenango, Bough (Sweet), Summer Queen, Gravenstein,(A) Jefferis, Porter, Maiden Blush.
Autumn.—Bailey (Sweet), Fameuse,(A) Jersey Sweet, Fall Pippin, Wealthy,(A) Mother, Twenty Ounce, Magnate.
Winter.—Jonathan(A) (Fig. 271), Hubbardston,(A) Grimes,(A) Tompkins King,(A) Wagener(A) (Fig. 272), Baldwin,(A) Yellow Bellflower, Tolman (Sweet), Northern Spy,(A) Red Canada,(A) Roxbury, McIntosh,(A) Yellow Newtown (Plate XXI), Golden Russet, Belmont, Melon, Lady, Rambo, York Imperial, Pomme Gris, Esopus (Spitzenburgh), Swaar, Peck (Pleasant), Rhode Island Greening, Sutton, Delicious, Stayman Winesap, Westfield (Seek-no-further).
For the South and Southwest the varieties named in the following list are of value:—
Early.—Red June, Yellow Transparent, Red Astrachan, Summer Queen, Benoni, Oldenburg, Gravenstein, Maiden Blush, Earlyripe,(A) Williams,(A) Early Cooper,(A) Horse.
Autumn.—Haas, Late Strawberry, Oconee, Rambo, Peck (Peck Pleasant), Carter Blue, Bonum,(A) Smokehouse,(A) Hoover.
Winter.—Shockley, Rome Beauty,(A) Smith Cider, Grimes, Buckingham, Jonathan,(A) Winesap, Kinnard, York Imperial, Gilpiri (Romanite), Ralls (Genet), Limbertwig, Royal Lumbertwig, Stayman Winesap,(A) Milam, Virginia Beauty,(A) Terry,(A) Ingram.(A)
In the Northwest only such varieties as are extremely hardy will be satisfactory, and among those likely to succeed we may mention:—
Early.—Yellow Transparent, Tetofski, Oldenburg.(A)
Autumn.—Fameuse, Longfield, Wealthy, McMahan,(A) McIntosh,(A) Shiawassee.
Winter.—Wolf River,(A) Hibernal, Northwestern (Greening), Pewaukee (Fig. 273), Switzer, Golden Russet, Patten (Greening).(A)
APRICOT.—This fruit is not often seen in home gardens in the East, although it deserves to be better known. When grown at all, it is likely to be trained on walls, after the English custom.
In the latitude of New York, the apricot has proved as hardy as the peach. Given the right conditions as to soil and exposure, it will yield abundant crops, ripening its fruits about three weeks in advance of early peaches.
The apricot usually thrives best on strong land; but otherwise the treatment given the peach suits it very well. The soil should be rather dry; especially should the subsoil be such that no water may stand around the roots. The exposure should be to the north or west to retard the blooming period, as the one great drawback to the successful fruiting is the early blooming and subsequent freezing of the flowers or the small fruits.
The two serious difficulties in the growing of apricots are the ravages of the curculio, and the danger to the flowers from the spring frosts. It is usually almost impossible to secure fruits from one or two isolated apricot trees, because the curculios will take them all. It is possible, also, that some of the varieties need cross-pollination.
Among the best kinds of apricots are Montgamet, Jackson, Royal, St. Ambroise, Early Golden, Harris, Roman (Fig. 274) and Moorpark. In the East, apricots are commonly worked on plums, but they also thrive on the peach.
The introduction of the Russian varieties, a few years ago, added to the list several desirable kinds that have proved hardier and a little later in blooming than the old kinds. The fruits of the Russian varieties, while not as large as the other varieties, fully equal many of them in flavor, and they are very productive. They bear more profusely and with less care than the old-fashioned and larger kinds.
Blackberry.—In a general way, the planting and care of a blackberry plantation is the same as required by raspberries. From the fact that they ripen later in the season, when droughts are most common, even greater attention should be given to placing them in land that is retentive of moisture, and to providing an efficient mulch, which can generally best be secured with a cultivator. The smaller-growing kinds (as Early Harvest and Wilson) may be planted 4 x 7 ft., the rank-growing varieties (as Snyder) 6 x 8 ft. Thorough cultivation through-out the season will help in a material degree to hold the moisture necessary to perfect a good crop. The soil should be cultivated very shallow, however, so as not to disturb the roots, as the breaking of the roots starts a large number of suckers that have to be cut out and destroyed. While hill culture (as recommended above) is desirable for the garden, commercial growers generally use continuous rows.
Blackberries, like dewberries and raspberries, bear but one crop on the cane. That is, canes which spring up this year bear next year. From 3 to 6 canes are sufficient to be left in each hill. The superfluous ones are thinned out soon after they start from the ground. The old canes should be cut out soon after fruiting, and burned. The new shoots should be pinched back at the height of 2 or 3 ft. if the plants are to support themselves. If to be fastened to wires, they may be allowed to grow throughout the season and be cut back when tied to the wires in winter or early spring.
Blackberry plants are sometimes laid down in cold climates,—the tops being bent over and held to the ground by earth or sods thrown on their tips (Fig. 155).
The most troublesome disease of the blackberry is orange rust (conspicuous on the under sides of the leaves), which often proves very destructive, particularly to Kittatinny and a few other sorts. There is no remedy, and on the first appearance of the disease the infected plants should be dug up and burned.
Varieties of blackberries.
Many of the better varieties of blackberries are lacking in hardiness, and cannot be grown except in the more favorable localities. Snyder and Taylor are most generally successful, although Wilson and Early Harvest are often grown on a large scale for market, and do well with winter protection. Eldorado is much like Snyder, that seems hardy and productive. Erie, Minnewaski, Kittatinny, and Early King are in many sections large and valuable sorts.
CHERRY.—Of cherries there are two common types, the sweet cherries and the sour cherries. The sweet cherries are larger and taller-growing trees. They comprise the varieties known as the hearts, bigarreaus, and dukes. The sour cherries (Fig. 275) include the various kinds of morellos and pie cherries, and these usually ripen after the sweet cherries.
The sour cherries make low, round-headed trees. The fruits are extensively used for canning. Sour cherries thrive well on clay loams. The sour cherry should be planted 18 by 18 ft. apart, in well-prepared, under-drained soil. The trees may be slightly trimmed back each year, keeping the head low and bushy.
The sweet cherries have proved disappointing in many instances from the rotting of the fruit. This may never be entirely avoided, but good cultivation, soil not too rich in nitrogen, attention to spraying, and picking the fruit when dry, will lessen the loss very much. In years of severe rotting the fruit should be picked before it becomes fully ripe, placed in a cool, airy room and allowed to color. It will be nearly as well flavored as if left on the tree; and, as the fungus usually attacks only the ripe fruit, a considerable part of the crop may be saved. Set the trees 25 or 30 ft. apart. Only very well-drained land should be devoted to sweet cherries, preferably one of a somewhat gravelly nature.
Leaf-blight is readily controlled by timely spraying with bordeaux mixture. The curculio or fruit worm may be controlled by jarring, as for plums, or by spraying. The jarring process is seldom employed with cherries for the curculio, inasmuch as the poison spray seems, for some reason, to be particularly effective on these fruits.
Varieties of cherry.
Of the sour varieties, May Duke (Fig. 36), Richmond, Dyehouse, Montmorency, Ostheim, Hortense (Fig. 34), Late Kentish, Suda, and Morello (English Morello) (Fig. 35) are the most valuable. The following sweet varieties are of value where they succeed: Rockport, (Yellow) Spanish, Elton, (Governor) Wood, Coe, Windsor, (Black) Tartarian, and Downer.
CRANBERRY.—The growing of cranberries in artificial bogs is an American industry. The common large cranberry of markets is also a peculiarly American fruit, since it is unknown in other countries except as the fruit is shipped there.
Cranberries are grown in bogs, which may be flooded. The whole area is kept under water during the winter time, largely to prevent the plants from winter injury by the heaving and freezing and thawing of the bogs. Flooding is also employed at intervals for the purpose of drowning out insects, mitigating drought, and protecting against frost and fires. The ordinary practice is to choose a bog which has a creek running through it, or through which some creek or ditch may be diverted. At the lower side of the bog flood-gates are provided, so that when the gates are shut, the water backs up and floods the area. It is best that the bog be comparatively flat, so that the water will be of approximately equal depth over the whole area. At the shallowest places the water should stand about a foot above the plants. The water is usually let on the bog early in December and kept on until April or early May. No flooding is done during the rest of the year unless there is some particular occasion therefor.
All the wild and turfy growth should be taken off the bog before the vines are set. This is done either by digging it off and removing it bodily, or by drowning it out by means of a year's flooding. The former method is generally considered to be the better. After the turfy growth is removed, the bog is smoothed, and covered 2 or 3 in. deep with clean sand. The vines are now set, the lower ends of them being shoved through the sand into the richer earth. In order to prevent a too rapid and tangled growth of vine, it is customary to resand the bog every three or four years to a depth of one-fourth or one-half inch. When sanding is not practicable, the vines may be mown off when they become too luxuriant.
The plants for setting are merely cuttings or branches of the vines. These cuttings may be 5 to 10 inches long. They are inserted into the ground in a hole made by a crowbar or stick. They are usually planted at distances of 12 to 18 inches each way, and the vines are allowed to cover the entire ground as with a mat. In three years a good crop should be secured, if the weeds and wild growth are kept down. A crop ranges between 50 to 100 barrels per acre.
CURRANT.—As the currant is one of the hardiest and most productive of fruits in the North, so is it often neglected, the patch allowed to become foul with grass, never thinned or trimmed, the worms eating the leaves until, in the course of time, the plants weaken and die. Along the fence is no place to plant currants, or, indeed, any other fruit; plant out in the open, at least 5 feet from anything that will interfere with cultivation.
No fruit crop will respond more readily to good care than the currant. Clean cultivation and a liberal use of manure or fertilizers will certainly be followed by well-paying crops. One-or two-year-old plants may be set, 4 by 6 feet. Trim the bush by cutting off most of the suckers below the surface of the ground. The currant should have cool moist soil. If the season is dry, a mulch of straw or leaves will assist the plants to establish themselves.
Currants are easily propagated by mature cuttings of the new or previous year's canes.
The red and white currants bear mostly on two-year-old or older wood. A succession of young shoots should be allowed to grow to take the place of the old bearing wood. Cut out the canes as they grow older. The partial shade afforded by a young orchard suits the currant well, and if the ground is in good condition, no bad results will follow to the orchard, provided the currants are removed before the trees need the entire feeding space.
A currant patch should continue in good bearing for 10 to 20 years, if properly handled. One very important point is to keep the old, weak canes cut out, and a succession of two to four new ones coming from the root each year.
To combat the currant worm, spray thoroughly with Paris green to kill the first brood, just as soon as holes can be seen in the lower leaves —usually before the plants are in bloom. For the second brood, if it appear, spray with white hellebore (p. 203). For borers, cut out and burn the affected canes.
Varieties of currants.
In most sections the Red Dutch will be found to be the most satisfactory variety, as the plants are much less injured by borers than are Cherry (Plate XXIII), Fay, and Versailles, which are larger and better varieties, and are to be preferred in sections where the borers are not troublesome. Victoria is a valuable market sort where borers are numerous, as it is little injured by them. The same is also true of (Prince) Albert, which is little attacked by currant worms and is particularly valuable as a late sort. White Dutch and White Grape are valuable light-colored varieties, and (Black) Naples as a variety for jelly. London (London Market) is also proving to be satisfactory in some sections.
DEWBERRY.—The dewberry may be called an early trailing blackberry. The culture is very simple. Support should be given to the canes, as they are very slender and rank growers. A wire trellis or large-meshed fence-wire answers admirably; or (and this is the better general method) they may be tied to stakes. The fruits are large and showy, which, combined with their earliness, makes them desirable; but they are usually deficient in flavor. The Lucretia (Fig. 276) is the leading variety.
Lay the canes on the ground in winter. In the spring tie all the canes from each plant to a stake. After fruiting, cut the old canes and burn them (as for blackberries). In the meantime, the young canes (for next year's fruiting) are growing. These may be tied up as they grow, to be out of the way of the cultivator. Dewberries are one to two weeks earlier than blackberries.
FIG.—The fig is little grown in the East except as a curiosity, but on the Pacific coast it has gained considerable prominence as an orchard fruit. Figs will stand considerable frost, and seedling or inferior varieties grow out-of-doors without protection as far north as Virginia. Many of the varieties fruit on young sprouts, and, inasmuch as the roots will stand considerable cold, these varieties will often give a few figs in the northern states. Figs have been fruited in the open ground in Michigan. In regions having ten degrees of frost, the fig should be laid down in winter. For this purpose the plants are pruned to branch from the ground, and the soft tops are bent to the surface and covered with earth. In commercial cultivation, fig trees grow large, and they stand 18 to 25 feet apart; but in gardens where they are to be bent over, they are to be kept as bushes.
Adriatic is the most commonly grown white fig. Among the other varieties are California Black or Mission Fig, Brown Ischia, Brown Turkey, White Ischia, and Celeste (Celestial).
GOOSEBERRY.—The gooseberry differs little from the currant in its requirements as to soil, pruning, and general care. The plants should be set 3 to 4 feet apart; rows 5 to 7 feet apart. Select a rich, rather moist soil. The tops need no winter protection. If mildew and worms are to be kept in check, spraying must be begun with the very first sign of trouble and be thoroughly done.
The propagation of the gooseberry is similar to that of the currant, although the practice of earthing up a whole plant, causing every branch thus covered to throw out roots, is practiced with the European varieties. The rooted branches are cut off the following spring and planted in nursery rows or sometimes directly in the field. In order to succeed with this method, the plant should have been cut back to the ground so that all the shoots are yearling.
Since the advent of the practice of spraying with fungicides to prevent mildew, the culture of the gooseberry has increased. There is now no reason why, with a little care, good crops of many of the best English varieties may not be grown.
A large part of the gooseberry crop is picked green for culinary purposes. Several of the English varieties and their derivatives have proved of value, having larger fruits than the natives (Fig. 277).
Varieties of gooseberries.
For ordinary use the Downing can generally be recommended. It is hardy, productive, of fair size, and greenish white in color. Houghton is even more hardy and productive, but the fruit is rather small and of a dark red color. Among the varieties of European origin that can be successfully grown, if the mildew can be prevented, are Industry, Triumph, Keepsake, Lancashire Lad, and Golden Prolific. Among other varieties that are promising are Champion, Columbus, Chautauqua, and Josselyn (Red Jacket).
GRAPE.—One of the surest of fruit crops is the grape, a crop each year being reasonably certain after the third year from the time of setting the vines; and the good amateur kinds are numerous.
The grape does well on any soil that is under good cultivation and well drained. A soil with considerable clay is better under these circumstances than a light, sandy loam. The exposure should be to the sun; and the place should admit of cultivation on all sides.
For planting, 1-or 2-year-old vines should be used, being set either in the fall or early spring. At planting, the vine is cut back to 3 or 4 eyes, and the roots are well shortened in. The hole in which the plant is to be set should be large enough to allow a full spreading of the roots. If the season should be dry, a mulch of coarse litter may be spread around the vine. If all the buds start, the strongest one or two may be allowed to grow. The canes arising from these buds should be staked and allowed to grow through the season; or in large plantations the first-year canes may be allowed to lie on the ground.
The second year one cane should be cut back to the same number of eyes as the first year. After growth begins in the spring, two of the strongest buds should be allowed to remain. These two canes now arising may be grown to a single stake through the second summer, or they may be spread horizontally on a trellis. These are the canes that form the permanent arms or parts of the vine. From them start the upright shoots which, in succeeding years, are to bear the fruits.
In order to understand the pruning of grapes, the operator must fully grasp this principle: Fruit is borne on wood of the present season, which arises from wood of the previous season. To illustrate: A growing shoot, or cane, of 1909 makes buds. In 1910 a shoot arises from each bud; and near the base of these shoots the grapes are borne (1 to 4 clusters on each). While every bud on the 1909 shoot may produce shoots or canes in 1910, only the strongest of these new canes will bear fruit. The skilled grape-grower can tell by the looks of his cane (as he prunes it in winter) which buds will give rise to the grape-producing wood the following season. The larger and stronger buds usually give best results; but if the cane itself is very big and stout, or if it is very weak and slender, he does not expect good results from any of its buds. A hard, well-ripened cane the diameter of a man's little finger is the ideal size.
Another principle to be mastered is this: A vine should bear only a limited number of clusters,—say from 30 to 80. A shoot bears clusters near its base; beyond these clusters the shoot grows on into a long, leafy cane. An average of two clusters may be reckoned to a shoot. If the vine is strong enough to bear 60 clusters, 30 good buds must be left at the pruning (which is done from December to late February).
The essential operation of pruning a grape vine, therefore, is each year to cut back a limited number of good canes to a few buds, and to cut off entirely all the remaining canes or wood of the previous season's growth. If a cane is cut back to 2 or 3 buds, the stub-like part which remains is called a spur. Present systems, however, cut each cane back to 8 or 10 buds (on strong varieties), and 3 or 4 canes are left,—all radiating from near the head or trunk of the vine. The top of the vine does not grow bigger from year to year, after it has once covered the trellis, but is cut back to practically the same number of buds each year. Since these buds are on new wood, it is evident that they are each year farther and farther removed from the head of the vine. In order to obviate this difficulty, new canes are taken out each year or two from near the head of the vine, and the 2-year-or 3-year-old wood is cut away.
The training of grapes is a different matter. A dozen different systems of training may be practiced on the same trellis and from the same style of pruning,—for training is only the disposition or arrangement of the parts.
On arbors, it is best to carry one permanent arm or trunk from each root over the framework to the peak. Each year the canes are cut back to short spurs (of 2 or 3 buds) along the sides of this trunk.
Grapes are set from 6 to 8 feet apart in rows which are 8 to 10 feet apart. A trellis made of 2 or 3 wires is the best support. Slat trellises catch too much wind and blow down. Avoid stimulating manures. In very cold climates, the vines may be taken off the trellis in early winter and laid on the ground and lightly covered with earth. Along the boundaries of home lots, where grapes are often planted, little is to be expected in the way of fruit because the ground is not well tilled.
The grape is subject to many insects and diseases, some of which are very destructive. The black-rot is the most usual trouble. See p. 209.
To produce bunches of high quality and free from rot and frost injury, grapes are sometimes bagged. When the grapes are about half grown, the bunch is covered with a grocer's manila bag. The bags remain until the fruit is ripe. The grapes usually mature earlier in the bags. The top of the bag is split, and the flaps are secured over the branch with a pin; Figs. 278, 279, 280 explain the operation.
In all the above discussion, the so-called native grapes alone are considered. In California, the European or vinifera types are grown, the requirements of which are radically different from those of the eastern kinds.
Varieties of grapes.
Under nearly all conditions, the Concord will be a valuable black variety, although Worden, which is a few days earlier, may be preferred by many. Moore (Moore Early) has been our best very early black variety, but is likely to be superseded by Campbell, which is a stronger vine, more productive, bunches larger, fruit of better quality, and of superior keeping qualities, making it valuable for shipping purposes. Catawba, Delaware, and Brighton are among the best red varieties, although Agawam and Salem are much used. Winchell (Green Mountain) is the best early white variety, and in most sections Niagara, a late white sort, does well. Diamond (Moore Diamond) is a white grape of better quality than Niagara.
Grapes under glass (S.W. Fletcher).
The European grapes rarely thrive out of doors in eastern America. Grape houses are necessary, with or without artificial heat. Fruit for home use may be grown very satisfactorily in a cold grapery (without artificial heat). A simple lean-to against the south side of a building or wall is cheap and serviceable. When a separate building is desired, an even-span house running north and south is preferable. There is no advantage in having a curved roof, except as a matter of looks. A compost of four parts rotted turf to one of manure is laid on a sloping cement bottom outside the house, making a border 12 feet wide and 2 feet deep. The cement may be replaced with rubble on well-drained soils, but it is a poor makeshift. Every three years the upper 6 inches of the border should be renewed with manure. The border inside the house is prepared likewise. Two-year-old potted vines are planted about 4 feet apart in a single row. Part of the roots go through a crevice in the wall to the outer border and part remain inside; or all may go outside if the house is desired for other purposes. One strong cane is trained to a wire trellis hanging at least 18 inches from the glass, and is cut back to 3 feet the first year, 6 the second, and 9 the third. Do not be in a hurry to get a long cane. Pruning is on the spur system, as recommended for arbors on p. 430. The vines are usually laid on the ground for winter and covered with leaves or wrapped with cloth.
As soon as the buds swell in early spring, tie the vines to the trellis and start out one shoot from each spur, rubbing off all others. After the berries begin to color, however, it is better to leave all further growth to shade the fruit. Pinch back each of these laterals two joints beyond the second bunch. To keep down red spider and thrips, the foliage should be sprayed with water every bright morning except during the blooming season. At least one-third of the berries should be thinned from each bunch; do not be afraid of taking out too many. Water the inside border frequently all through the summer, and the outside occasionally if the season is dry. Mildew may appear in July. The best preventives are to syringe faithfully, admit air freely, and sprinkle sulfur on the ground.
Fruit may be kept fresh on the vines in a warm (or artificially heated) grapery until late December; in a coldhouse it must be picked before frost. After the fruit is off, ventilate from top and bottom and withhold water, so as thoroughly to ripen the wood. Along in November the canes are pruned, covered with straw or wrapped with mats and laid down till spring. Black Hamburg is superior to all other varieties for a cold grapery; Bowood Muscat, Muscat of Alexandria, and Chasselas Musque may be added in the warmhouse. Good vines will live and bear almost indefinitely.
MULBERRY.—Both for fruit and ornament the mulberry should be more generally planted. Even if the fruit is not to the taste, the tree is naturally open-centered and round-headed, and is an interesting subject; some of the varieties have finely cut leaves. The fruits are in great demand by the birds, and after they begin to ripen the strawberry beds and cherry trees are freer from robins and other fruit-eating birds. For this reason alone they are a valuable tree for the fruit-grower. Trees may be purchased cheaper than one can propagate them.
If planted in orchard form, place them 25 to 30 feet apart. About the borders of a place they can go closer. The Russian varieties are often planted for windbreaks, for they are very hardy and thrive under the greatest neglect; and for this purpose they may be planted 8 to 20 feet apart. The Russians make excellent screens. They stand clipping well. The fruit of the Russians varies in quality, as the trees are usually directly from seed; but now and then a tree bears excellent fruit.
New American, Trowbridge, and Thorburn are leading kinds of fruit-bearing mulberries for the North. The true Downing is not hardy in the northern states; but New American is often sold under this name. Mulberries thrive in any good soil, and need no special treatment.
NUTS.—The nut trees demand too much room for most home-ground fruit plantations, although they are also useful for windbreaks and shade. The hickories, all American, make excellent lawn trees, and should be better known. The filberts and cobnuts, small trees or bushes, are not successfully grown in this country except in very special cases.
The commercial nut-growing in the United States and Canada is chiefly of almonds, walnuts, and pecans, with some attempt at chestnuts. Of these the chestnut is the most adaptable for home places in the northeastern section.
Of chestnuts there are three types in cultivation: the European, the Japanese, and the American. The American, or native chestnuts, of which there are several improved varieties, are the hardiest and most reliable, and the nuts are the sweetest, but they are also the smallest. The Japanese varieties are usually injured by the winter in central New York. The European varieties are somewhat hardier, and some of the varieties will thrive in the northern states. Chestnuts are very easily grown, although the bark disease now threatens them. They usually bear better when two or more trees are planted near each other. Sprouts in old chestnut clearings are often allowed to remain, and sometimes they are grafted to the improved varieties. The young trees may be grafted in the spring by the whip-graft or cleft-graft method; but the cions should be perfectly dormant, and the operation should be very carefully done. Even with the best workmanship, a considerable percentage of the grafts are likely to fail or to break off after two or three years. The most popular single variety of chestnut is the Paragon, which bears large and excellent nuts when the tree is very young. When the home ground is large enough, two or three of these trees should be planted near the borders.
ORANGE.—Oranges are grown extensively in Florida, in places along the Gulf, and in many parts of California, but in the most favored sections there is occasionally some injury from cold or frost to the trees or fruit.
The soil preferred for oranges in California is a rich, deep alluvium, avoiding hard-pan or adobe subsoils. Stagnant water in the subsoil is a fatal defect. Although they can be grown near the ocean at a lower level, an elevation of 600 to 1200 feet is generally desirable. While southern California is particularly adapted to orange culture, the fruit is successfully raised along the foot-hills of the San Joaquin and Sacramento valleys and in other parts of the state.
In Florida, pine lands with a clay subsoil are generally preferred for oranges, but if properly handled, good results can be obtained from hammock land. As elevated spots cannot be secured, a timber belt surrounding the orchard or along the north and west sides is desirable.
The distance for the large-growing kinds of orange in the orchard is from 25 to 30 feet each way, but the half-dwarf kinds, such as Bahia or Washington Navel, may be as close as 20 feet each way, although 25 feet will be desirable. If the roots are sacked, the trees should be placed in the hole without removing the covering, and the soil should then be packed about them; but if they are puddled, a mound should be made in the bottom of the hole. In the center an opening should be made into which the tap-root can be inserted. After the soil has been firmly packed about it, the other roots should be spread out and the hole filled with good soil, packing it carefully. Care should be taken that the roots are not exposed in handling the trees, and if the weather is hot and dry, the tops should be shaded. Water may often be used with good results in settling the soil about the roots.
When transplanted, the tops should be cut back in proportion to the amount of roots lost in digging the trees. The head is usually started with the branches about 2 feet from the ground. Each year while the trees are small, the strong shoots should be cut back to preserve a symmetrical form and the weak and surplus shoots should be removed.
The cultivation of orange orchards should be the same as recommended for other fruits, except that as they grow in hot, dry climates, it should be even more thorough, that the evaporation of moisture from the soil may be reduced to a minimum. California growers have found that by frequent shallow cultivation they can reduce the amount of water that must be applied by irrigation, and that frequent tillage and a little water will give better results than little or no cultivation and a large amount of water. The amount of water required will also depend on the season and the character of the soil. Thus on strong soils and after a heavy rainfall no irrigation will be required, while sandy soils will need irrigating as often as once in three or four weeks from May to October. As a general rule, two or three irrigations in a season will be ample. When used at all, water should be applied in sufficient quantities to wet down to the roots of the trees. Frequent scanty waterings may do much harm. The water is usually applied in furrows, and for young trees there should be one on either side of each row, but as the roots extend the number should be increased, until when five or six years old the entire orchard should be irrigated from furrows 4 or 5 feet apart. In Florida, irrigation is not practiced.
Cover-cropping in winter is now common in Florida and California, some of the leguminous crops being used.
Varieties of the orange.
Among the best varieties are: Bahia, commonly known as Washington Navel, Thompson Improved, Maltese Blood, Mediterranean Sweet, Paper Rind St. Michael, and Valencia. Homosassa, Magnum Bonum, Nonpareil, Boone, Parson Brown, Pineapple, and Hart are favorites in Florida. The tangerines and mandarins, or the "kid-glove" oranges, have a thin rind that is easily detached from the rather dry pulp. Orange trees are frequently injured by various scale insects, but for several of the most troublesome kinds, insect parasites have been found that keep them partially or wholly in check, and for others the trees are sprayed, or fumigated with hydrocyanic acid gas.
PEACH.—Given the proper exposure, peaches may be fruited in many sections where now it is thought impossible to have a crop. It is usually the practice of the amateur to set peach trees in the shelter of some building, exposed on the south or east to the sun, and "in a pocket" as regards winds. This should be reversed, except in the close vicinity of large bodies of water. The fruit-buds of peaches will stand very cold weather when perfectly dormant, often as low as 12 deg. or 18 deg. below zero in New York; but if the buds once become swollen, comparatively light freezing will destroy the crop. Therefore, if the trees be set on elevations where a constant air drainage may be obtained, sheltered, if at all, on the south and east from the warming influence of the sun, the buds will remain dormant until the ground becomes warm, and the chances of a failure will be lessened. This advice applies mostly to interior sections.
A well-drained, sandy loam or gravelly soil suits the peach better than a heavy soil; but if the heavier soil is well drained, good crops may be secured.
Peaches are short-lived at best, and one should be satisfied with three or four crops from each tree. They bear young, usually a partial crop the third year. If a crop may be had every other year until the trees are eight or ten years old, they will have well repaid the effort of cultivation. But they often bear twice this long. Young trees may be set every four or five years to replace older ones, thus having trees at a bearing age at all times on a small place. Trees should be set 14 to 18 feet apart each way.
Peach trees are always bought when they are one year old, that is, one year from the bud. For example, the bud is inserted in the fall of 1909. It remains dormant until the spring of 1910, when it pushes into vigorous growth; and in the fall of 1910 the tree is ready for sale. Peach trees that are more than a year old are scarcely worth the buying. It is a common practice, when setting peach trees, to prune them back to a whip, leaving a stub bearing not more than one bud where each branch is cut off.
The three great enemies of the peach are the borer, the yellows, and the curculio.
The borer is best handled by digging it out every spring and fall. Trees attacked by the borer have an exudation of gum about the crown. If the borers are dug out twice a year, they will not get sufficient start to make the operation very laborious. It is the only sure way.
The yellows is a communicable disease, the cause of which is not definitely known. It shows itself in the fruit ripening prematurely, with distinct red spots which extend through the flesh, and later by the throwing out of fine, branching, twiggy tufts along the main branches (Fig. 215). The only treatment is to pull out the trees and burn them. Other trees may be set in the same places.
The curculio must be captured by jarring on sheets (see Plum).
Varieties of the peach.
For home use it is advisable to provide varieties that will ripen in succession, but for market purposes, in most sections, the medium and late kinds should be most extensively planted. Although there are many varieties that have a local reputation, but are not commonly found in the nurseries, the following kinds are well known, and can be generally grown with success: Alexander, Hale Early, Rivers, St. John, Bishop, Connett (Southern Early), Carman, Crawford (Early and Late), Oldmixon, Lewis, Champion, Sneed, Greensboro, Kalamazoo, Stump, Elberta, Ede (Capt. Ede), Stevens (Stevens' Rareripe), Crosby, Gold Drop, Reeves, Chairs, Smock, Salway, and Levy (Henrietta).
PEAR.—No fruit plantation should be considered complete without trees of various kinds of pears, ripening fruits from early in August till winter. The late varieties are generally good keepers, and extend the season into February, thus supplying fruit for six or seven months.
As the pear grows to perfection on quince, the dwarf tree is peculiarly adapted to planting on small home grounds, and is often used as a boundary plant, or to serve the purpose of a screen. These dwarf trees should be set deep—4 to 6 inches below the union—to prevent the stock from growing. Dwarf trees may be set as near together as 10 to 16 feet, while the standard or tall-growing pears should be set 18 to 25 feet apart. Trees are planted when two or three years old.
The pear thrives on clay soil, if well under-drained, and for this reason may succeed in places where other fruits might fail. A good, steady growth should be maintained, but the use of nitrogenous manures should be avoided, as they tend to make a rank growth and invite attacks of pear blight, which is the worst enemy of the pear (p. 211).
