Home Vegetable Gardening Part 15

Do not, however, depend upon this knowledge to the extent of letting all your preparations for planting go until your stock is on hand. Be ready to set it the day it arrives, if possible.

PLANTING

Planting can be done in either spring or fall. As a general rule, north of Philadelphia and St. Louis, spring planting will be best; south of that, fall planting. Where there is apt to be severe freezing, "heaving," caused by the alternate freezing and thawing; injury to the newly set roots from too severe cold; and, in some western sections, "sun-scald" of the bark, are three injuries which may result. If trees are planted in the fall in cold sections, a low mound of earth, six to twelve inches high, should be left during the winter about each, and leveled down in the spring. If set in the spring, where hot, dry weather is apt to follow, they should be thoroughly mulched with litter, straw or coa.r.s.e manure, to preserve moisture--care being taken, however, against field mice and other rodents.

The trees may either be set in their permanent positions as soon as bought, or grown in "nursery rows" by the purchaser for one or two years after being purchased. In the former case, it will be the best policy to get the strongest, straightest two-year stock you can find, even if they cost ten or fifteen cents apiece more than the "mediums."

The former method is the usual one, but the latter has so many advantages that I give it the emphasis of a separate paragraph, and urge every prospective planter to consider it carefully.

In the first place, then, you get your trees a little cheaper. If you purchase for nursery row planting, six-foot to seven-foot two-year-old apple trees, of the standard sorts, should cost you about thirty cents each; one-year "buds," six feet and branched, five to ten cents less.

This gain, however, is not an important one--there are four others, each of which makes it worth while to give the method a trial. First, the trees being all together, and in a convenient place, the chances are a hundred to one that you will give them better attention in the way of spraying, pruning and cultivating--all extremely important in the first year's growth. Second, with the year gained for extra preparation of the soil where they are to be placed permanently, you can make conditions just right for them to take hold at once and thrive as they could not do otherwise. Third, the shock of transplanting will be much less than when they are s.h.i.+pped from a distance--they will have made an additional growth of dense, short roots and they will have become acclimated. Fourth, you will not have wasted s.p.a.ce and time with any backward black sheep among the lot, as these should be discarded at the second planting. And then there is one further reason, psychological perhaps, but none the less important; you will watch these little trees, which are largely the result of your own labor and care, when set in their permanent positions, much more carefully than you would those direct from the nursery. I know, both from experience and observation, how many thrifty young trees in the home orchard are done to an untimely death by children, careless workmen, and other animals.

So if you can put a twelve-month curb on your impatience, get one-year trees and set them out in a straight row right in your vegetable garden where they will take up very little room. Keep them cultivated just as thoroughly as the rest of your growing things. Melons, or beans, or almost any low-growing vegetable can be grown close beside them.

If you want your garden to pay for your whole lot of fruit trees this season dig up a hole about three feet in diameter wherever a tree is to "go permanently." Cut the sod up fine and work in four or five good forkfuls of well rotted manure, and on these places, when it is warm enough, plant a hill of lima pole-beans-the new sort named Giant-podded Pole Lima is the best I have yet seen. Place a stout pole, eight to ten feet high, firmly in each hole. Good lima beans are always in demand, and bring high prices.

Let us suppose that your trees are at hand, either direct from the nursery or growing in the garden. You have selected, if possible, a moist, gravelly loam on a slope or slight elevation, where it is naturally and perfectly drained. Good soil drainage is imperative.

Coa.r.s.e gravel in the bottom of the planting hole will help out temporarily. If the land is in clover sod, it will have the ideal preparation, especially if you can grow a patch of potatoes or corn on it one year, while your trees are getting further growth. In such land the holes will not have to be prepared. If, however, you are not fortunate enough to be able to devote such a s.p.a.ce to fruit trees, and in order to have them at all must place them along your wall or scattered through the grounds, you can still give them an excellent start by enriching the soil in spots beforehand, as suggested above in growing lima beans. In the event of finding even this last way inapplicable to your land, the following method will make success certain: Dig out holes three to six feet in diameter (if the soil is very hard, the larger dimension), and twelve to eighteen inches deep.

Mix thoroughly with the excavated soil a good barrowful of the oldest, finest manure you can get, combined with about one-fourth or one-fifth its weight of South Carolina rock (or acid phosphate, if you cannot get the rock). It is a good plan to compost the manure and rock in advance, or use the rock as an absorbent in the stable. Fill in the hole again, leaving room in the center to set the tree without bending or cramping any roots. Where any of these are injured or bruised, cut them off clean at the injured spot with a sharp knife. Shorten any that are long and straggling about one-third to one-half their length. Properly grown stock should not be in any such condition.

Remember that a well planted tree will give more fruit in the first ten years than three trees carelessly put in. Get the tree so that it will be one to three inches deeper in the soil than when growing in the nursery.

Work the soil in firmly about the roots with the fingers or a blunt wooden "tamper"; do not be afraid to use your feet. When the roots are well covered, firm the tree in by putting all your weight upon the soil around it. See that it is planted straight, and if the "whip," or small trunk, is not straight stake it, and tie it with rye straw, raffia or strips of old cloth-never string or wire. If the soil is very dry, water the root copiously while planting until the soil is about half filled in, never on the surface, as that is likely to cause a crust to form and keep out the air so necessary to healthy growth.

Prune back the "leader" of the tree-the top above the first lateral branches, about one-half. Peach trees should be cut back more severely.

Further information in regard to pruning, and the different needs of the various fruits in regard to this important matter, will be given in the next chapter.

SETTING

Standard apple trees, fully grown, will require thirty to forty-five feet of s.p.a.ce between them each way. It takes, however, ten or twelve years after the trees are set before all of this s.p.a.ce is needed. A system of "fillers," or inter-planting, has come into use as a result of this, which will give at least one hundred per cent, more fruit for the first ten years. Small-growing standards, standard varieties on dwarf stock, and also peaches, are used for this purpose in commercial orchards. But the principle may be applied with equally good results to the home orchard, or even to the planting of a few scattered trees. The standard dwarfs give good satisfaction as permanent fillers. Where s.p.a.ce is very limited, or the fruit must go into the garden, they may be used in place of the standard sorts altogether. The dwarf trees are, as a rule, not so long-lived as the standards, and to do their best, need more care in fertilizing and manuring; but the fruit is just as good; just as much, or more, can be grown on the same area; and the trees come into bearing two to three years sooner. They cost less to begin with and are also easier to care for, in spraying and pruning and in picking the fruit.

CULTIVATION

The home orchard, to give the very finest quality of fruit, must be given careful and thorough cultivation. In the case of scattered trees, where it is not practicable to use a horse, this can be given by working a s.p.a.ce four to six feet wide about each tree. Every spring the soil should be loosened up, with the cultivator or fork, as the case may be, and kept stirred during the early part of the summer. Unless the soil is rich, a fertilizer, high in potash and not too high in nitrogen, should be given in the spring. Manure and phosphate rock, as suggested above, is as good as any. In case the foliage is not a deep healthy green, apply a few handfuls of nitrate of soda, working it into the soil just before a rain, around each tree.

About August 1st the cultivation should be discontinued, and some "cover crop" sown. Buckwheat and crimson clover is a good combination; as the former makes a rapid growth it will form, if rolled down just as the apples are ripening, a soft cus.h.i.+on upon which the windfalls may drop without injury, and will furnish enough protection to the crimson clover to carry it through most winters, even in cold climates.

In addition to the filler crops, where the ground is to be cultivated by horse, potatoes may be grown between the rows of trees; or fine hills of melons or squash may be grown around scattered trees, thus, incidentally, saving a great deal of s.p.a.ce in the vegetable garden. Or why not grow a few extra fancy strawberries in the well cultivated spots about these trees? Neither they nor the trees want the ground too rich, especially in nitrogen, and conditions suiting the one would be just right for the others.

It may seem to the beginner that fruit-growing, with all these things to keep in mind, is a difficult task. But it is not. I think I am perfectly safe in saying that the rewards from nothing else he can plant and care for are as certain, and surely none are more satisfactory. If you cannot persuade yourself to try fruit on any larger plan, at least order half a dozen dwarf trees (they will cost about twenty cents apiece, and can be had by mail). They will prove about the best paying investment you ever made.

CHAPTER XVII

PRUNING, SPRAYING, HARVESTING

The day has gone, probably forever, when setting out fruit trees and giving them occasional cultivation, "plowing up the orchard" once in several years, would produce fruit. Apples and pears and peaches have occupied no preferred position against the general invasion of the realm of horticulture by insect and fungous enemies. The fruits have, indeed, suffered more than most plants. Nevertheless there is this encouraging fact: that, though the fruits may have been severely attacked, the means we now have of fighting fruit-tree enemies, if thoroughly used, as a rule are more certain of accomplis.h.i.+ng their purpose, and keeping the enemies completely at bay, than are similar weapons in any other line of horticultural work.

With fruit trees, as with vegetables and flowers, the most important precaution to be taken against insects and disease is to _have them in a healthy, thriving, growing condition_. It is a part of Nature's law of the survival of the fittest that any backward or weakling plant or tree seems to fall first prey to the ravages of destructive forces.

For these reasons the double necessity of maintaining at all times good fertilization and thorough cultivation will be seen. In addition to these two factors, careful attention in the matter of pruning is essential in keeping the trees in a healthy, robust condition. As explained in a previous chapter, the trees should be started right by pruning the first season to the open-head or vase shape, which furnishes the maximum of light and air to all parts of the tree. Three or four main branches should form the basis of the head, care being taken not to have them start from directly opposite points on the trunk, thus forming a crotch and leaving the tree liable to splitting from winds or excessive crops. If the tree is once started right, further pruning will give little trouble. Cut out limbs which cross, or are likely to rub against each other, or that are too close together; and also any that are broken, decayed, or injured in any way. For trees thus given proper attention from the start, a short jackknife will be the only pruning instrument required.

The case of the old orchard is more difficult. Cutting out too many of the old, large limbs at one time is sure to give a severe shock to the vitality of the tree. A better plan is, first, to cut off _close_ all suckers and all small new-growth limbs, except a few of the most promising, which may be left to be developed into large limbs; and then as these new limbs grow on, gradually to cut out, using a fine-tooth saw and painting the exposed surfaces, the surplus old wood. Apples will need more pruning than the other fruits. Pears and cherries need the least; cutting back the ends of limbs enough to keep the trees in good form, with the removal of an occasional branch for the purpose of letting in light and air, is all the pruning they will require. Of course trees growing on rich ground, and well cultivated, will require more cutting back than those growing under poorer conditions. A further purpose of pruning is to effect indirectly a thinning of the fruit, so that what is grown will be larger and more valuable, and also that the trees may not become exhausted by a few exceptionally heavy crops. On trees that have been neglected and growing slowly the bark sometimes becomes hard and set. In such cases it will prove beneficial to sc.r.a.pe the bark and give a wash applied with an old broom. Whitewash is good for this purpose, but soda or lye answers the same purpose and is less disagreeably conspicuous. Slitting the bark of trunks and the largest limbs is sometimes resorted to, care being taken to cut through the bark only; but such practice is objectionable because it leaves ready access to some forms of fungous disease and to borers.

Where extra fine specimens of fruit are desired, thinning is practiced.

It helps also to prevent the tree from being overtaxed by excessive crops. But where pruning is thoroughly done this trouble is usually avoided. Peaches and j.a.pan plums are especially benefited by thinning, as they have a great tendency to overbear. The spread of fruit diseases, especially rot in the fruit itself, is also to some extent checked.

Of fruit-tree enemies there are some large sorts which may do great damage in short order--rabbits and field mice. They may be kept away by mechanical protection, such as wire, or by heaping the earth up to a height of twelve inches about the tree trunk. Or they may be caught with poisoned baits, such as boiled grain in which a little Rough on Rats or similar poison has been mixed. The former method for the small home garden is little trouble, safer to Fido and Tabby, and the most reliable in effect.

Insects and scale diseases are not so easily managed; and that brings us to the question of spraying and of sprays.

For large orchards the spray must, of course, be applied with powerful and expensive machinery. For the small fruit garden a much simpler and very moderate priced apparatus may be acquired. The most practical of these is the bra.s.s-tank compressed-air sprayer, with extension rod and mist-spray nozzle. Or one of the knapsack sprayers may be used. Either of these will be of great a.s.sistance not only with the fruit trees, but everywhere in the garden. With care they will last a good many years.

Whatever type you get, be sure to get a bra.s.s machine; as cheaper ones, made of other metal, quickly corrode from contact with the strong poisons used.

APPLE ENEMIES

The insects most commonly attacking the apple are the codlin-moth, tent-caterpillar, canker-worm and borer. The codlin-moth lays its eggs on the fruit about the time of the falling of the blossoms, and the larvae when hatched eat into the young fruit and cause the ordinary wormy apples and pears. Owing to these facts, it is too late to reach the trouble by spraying after the calyx closes on the growing fruit.

Keep close watch and spray immediately upon the fall of the blossoms, and repeat the spraying a week or so (not more than two) later. For spray use Paris green at the rate of 1 lb., or a.r.s.enate of lead (paste or powder, less of the latter: see accompanying directions) at the rate of 4 lbs. to 100 gallons of water, being careful to have a thorough mixture. During July, tie strips of burlap or old bags around the trunks, and every week or so destroy all caterpillars caught in these traps. The tent-caterpillar may be destroyed while in the egg state, as these are plainly visible around the smaller twigs in circular, brownish ma.s.ses. (See ill.u.s.tration.) Upon hatching, also, the nests are obtrusively visible and may be wiped out with a swab of old bag, or burned with a kerosene torch. Be sure to apply this treatment before the caterpillar begins to leave the nest. The treatment recommended for codlin-moths is also effective for the tent-caterpillar.

The canker-worm is another leaf-feeding enemy, and can be taken care of by the Paris green or a.r.s.enate spray.

The railroad-worm, a small white maggot which eats a small path in all directions through the ripening fruit, cannot be reached by spraying, as he starts life inside the fruit; but where good clean tillage is practiced and no fallen fruit is left to lie and decay under the trees, he is not apt to give much trouble.

The borer's presence is indicated by the dead, withered appearance of the bark, beneath which he is at work, and also by small amounts of sawdust where he entered. Dig him out with a sharp pocket-knife, or kill him inside with a piece of wire.

The most troublesome disease of the apple, especially in wet seasons, is the apple-scab, which disfigures the fruit, both in size and in appearance, as it causes blotches and distortions. Spray with Bordeaux mixture, 5-5-50, or 3-3-50 (see formulas below) three times: just before the blossoms open, just as they fall, and ten days to two weeks after they fall. The second spraying is considered the most important.

The San Jose scale is of course really an insect, though in appearance it seems a disease. It is much more injurious than the untrained fruit grower would suppose, because indirectly so. It is very tiny, being round in outline, with a raised center, and only the size of a small pinhead. Where it has once obtained a good hold it multiplies very rapidly, makes a scaly formation or crust on the branches, and causes small red-edged spots on the fruit (see ill.u.s.tration). For trees once infested, spray thoroughly both in fall, after the leaves drop, and again in spring, _before_ growth begins. Use lime-sulphur wash, or miscible oil, one part to ten of water, thoroughly mixed.

CHERRY ENEMIES

Sour cherries are more easily grown than the sweet varieties, and are less subject to the attacks of fruit enemies. Sweet cherries are troubled by the curculio, or fruit-worm, which attacks also peaches and plums. Cherries and plums may be sprayed, when most of the blossoms are off, with a strong a.r.s.enate of lead solution, 5 to 8 lbs. to 100 gals.

water. In addition to this treatment, where the worms have once got a start, the beetles may be destroyed by spreading a sheet around and beneath the tree, and every day or so shaking or jarring them off into it, as described below.

PEACH ENEMIES

Do not spray peaches. For the curculio, within a few days after the flowers are off, take a large sheet of some cheap material to use as a catcher. For large orchards there is a contrivance of this sort, mounted on a wheelbarrow frame, but for the home orchard a couple of sheets laid upon the ground, or one with a slit from one side to the center, will answer. If four short, sharp-pointed stakes are fastened to the corners, and three or four stout hooks and eyes are placed to reunite the slit after the sheet is placed about the tree, the work can be more thoroughly done, especially on uneven ground. After the sheet is placed, with a stout club or mallet, padded with a heavy sack or something similar to prevent injury to the bark, give a few sharp blows, well up from the ground. This work should be done on a cloudy day, or early in the morning--the colder the better--as the beetles are then inactive. If a considerable number of beetles are caught the operation should be repeated every two or three days. Continue until the beetles disappear.

Peaches are troubled also by borers, in this case indicated by ma.s.ses of gum, usually about the crown. Dig out or kill with a wire, as in the case of the apple-borer. Look over the trees for borers every spring, or better, every spring and fall.

Another peach enemy is the "yellows," indicated by premature ripening of the fruit and the formation of stunted leaf tufts, of a light yellow color. This disease is contagious and has frequently worked havoc in whole sections. Owing to the work of the Agricultural Department and the various State organizations it is now held in check. The only remedy is to cut and burn the trees and replant, in the same places if desired, as, the disease does not seem to be carried by the soil.
