For the mysteries of hybridizing and raising new seedlings, grafting, hot-house and cold grapery culture, the reader must look in more extended works than this, and to writers who have had experience in these matters.
We shall next consider three fruits which upon the Home Acre may be regarded as forming a natural group-peaches, plums, and raspberries, if any one expresses surprise that the last-named fruit should be given this relationship, I have merely to reply that the raspberry thrives in the partial shade produced by such small trees as the peach and plum. Where there is need of economy of space it is well to take advantage of this fact, for but few products of the garden give any satisfaction when contending with roots below and shade above.
We have taken it for granted that some grape-vines would be planted in the two borders extending through the centre of the garden, also that there would be spaces left which might be filled with peach and plum trees and small flowering shrubs. If there is to be a good-sized poultry-yard upon the acre, we should advise that plums be planted in that; but we will speak of this fruit later, and now give our attention to that fruit which to the taste of many is unrivalled—the peach.
With the exception of the strawberry, it is perhaps the only fruit for which I prefer spring planting. At the same time, I should not hesitate to set out the trees in autumn. The ground should be good, but not too highly fertilized. I prefer young trees but one year old from the bud. If set out in the fall, I should mound up the earth eighteen inches about them, to protect the roots and stem, and to keep the tree firmly in the soil. With this precaution, I am not sure but that fall planting has the greater advantage, except when the climate is very severe and subject to great alternations. Plant with the same care and on the same principles which have been already described. If a careful system of pruning is to be adopted, the trees may be set out twelve feet apart; but if they are to be left to grow at will, which I regret to say is the usual practice, they should be planted fifteen feet from each other.
There are many good reasons why the common orchard culture of the peach should not be adopted in the garden. There is no fruit more neglected and ill-treated than the beautiful and delicious peach. The trees are very cheap, usually costing but a few cents each; they are bought by the thousand from careless dealers, planted with scarcely the attention given to a cabbage-plant, and too often allowed to bear themselves to death. The land, trees, and cultivation cost so little that one good crop is expected to remunerate for all outlay. If more crops are obtained, there is so much clear gain. Under this slovenly treatment there is, of course, rapid deterioration in the stamina of the peach. Pits and buds are taken from enfeebled trees for the purpose of propagation, and so tendencies to disease are perpetuated and enhanced. Little wonder that, the fatal malady, the "yellows," has blighted so many hopes! I honestly believe that millions of trees have been sold in which this disease existed from the bud. If fine peaches were bred and propagated with something of the same care that is bestowed on blooded stock, the results would soon be proportionate. Gardeners abroad often give more care to one tree than hundreds receive here. Because the peach has grown so easily in our climate, we have imposed on its good-nature beyond the limits of endurance, and consequently it is not easy to get sound, healthful trees that will bear year after year under the best of treatment, as they did with our fathers with no care at all. I should look to men who had made a reputation for sending out sound, healthful stock grown under their own eyes from pits and wood which they know to be free from disease. Do not try to save a few pennies on the first cost of trees, for the probabilities are that such economy will result in little more than the "yellows."
In large orchards, cultivated by horse-power, the stems of the trees are usually from four to six feet high; but in the garden this length of stem is not necessary, and the trees can be grown as dwarf standards, with stems beginning to branch two feet from the ground. A little study of the habit of growth in the peach will show that, to obtain the best results, the pruning-shears are almost as essential as in the case of the grape-vine. More than in any other fruit-tree, the sap tends strongly toward the ends of the shoots. Left to Nature, only the terminal buds of these will grow from year to year; the other buds lower down on the shoots fail and drop off. Thus we soon have long naked reaches of unproductive wood, or sucker-like sprouts starting from the bark, which are worse than useless. Our first aim should be to form a round, open, symmetrical head, shortening in the shoots at least one-half each year, and cutting out crossing and interlacing branches. For instance, if we decide to grow our trees as dwarf standards, we shall cut back the stems at a point two feet from the ground the first spring after planting, and let but three buds grow, to make the first three or leading branches. The following spring we shall cut back the shoots that have formed, so as to make six leading branches. Thereafter we shall continue to cut out and back so as to maintain an open head for the free circulation of air and light.
To learn the importance of rigorous and careful pruning, observe the shoots of a vigorous peach-tree, say three or four years old. These shoots or sprays are long and slender, lined with fruit-buds. You will often find two fruit-buds together, with a leaf-bud between them. If the fruit-buds have been uninjured by the winter, they will nearly all form peaches, far more than the slender spray can support or mature. The sap will tend to give the most support to all growth at the end of the spray or branch. The probable result will be that you will have a score, more or less, of peaches that are little beyond skin and stones. By midsummer the brittle sprays will break, or the limbs split down at the crotches. You may have myriads of peaches, but none fit for market or table. Thousands of baskets are sent to New York annually that do not pay the expenses of freight, commission, etc.; while the orchards from which they come are practically ruined. I had two small trees from which, one autumn, I sold ten dollars' worth of fruit. They yielded more profit than is often obtained from a hundred trees.
Now, in the light of these facts, realize the advantages secured by cutting back the shoots or sprays so as to leave but three or four fruit-buds on each. The tree can probably mature these buds into large, beautiful peaches, and still maintain its vigor. By this shortening-in process you have less tree, but more fruit. The growth is directed and kept within proper limits, and the tree preserved for future usefulness. Thus the peach-trees of the garden will not only furnish some of the most delicious morsels of the year, but also a very agreeable and light phase of labor. They can be made pets which will amply repay all kindness; and the attentions they most appreciate, strange to say, are cutting and pinching. The pruning-shears in March and early April can cut away forming burdens which could not be borne, and pinching back during the summer can maintain beauty and symmetry in growth. When the proprietor of the Home Acre has learned from experience to do this work judiciously, his trees, like the grape-vines, will afford many hours of agreeable and healthful recreation. If he regards it as labor, one great, melting, luscious peach will repay him. A small apple, pear, or strawberry usually has the flavor of a large one; but a peach to be had in perfection must be fully matured to its limit of growth on a healthful tree.
Let no one imagine that the shortening in of shoots recommended consists of cutting the young sprays evenly all round the trees as one would shear a hedge. It more nearly resembles the pruning of the vine; for the peach, like the vine, bears its fruit only on the young wood of the previous summer's growth. The aim should be to have this young bearing wood distributed evenly over the tree, as should be true of a grape-vine. When the trees are kept low, as dwarf standards, the fruit is more within reach, and less liable to be blown off by high winds. Gradually, however, if the trees prove healthful, they will get high enough up in the world.
Notwithstanding the rigorous pruning recommended, the trees will often overload themselves; and thinning out the young peaches when as large as hickory nuts is almost imperative if we would secure good fruit. Men of experience say that when a tree has set too much fruit, if two-thirds of it are taken off while little, the remaining third will measure and weigh more than would the entire crop, and bring three times as much money. In flavor and beauty the gain will certainly be more than double.
