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.
Throughout its entire growth and fruiting life the peach-tree needs good cultivation, and also a good but not overstimulated soil. Well-decayed compost from the cow-stable is probably the best barnyard fertilizer. Wood-ashes are peculiarly agreeable to the constitution of this tree, and tend to maintain it in health and bearing long after others not so treated are dead. I should advise that half a peck be worked in lightly every spring around each tree as far as the branches extend. When enriching the ground about a tree, never heap the fertilizer round the trunk, but spread it evenly from the stem outward as far as the branches reach, remembering that the head above is the measure of the root extension below. Air-slacked lime is also useful to the peach in small quantities; and so, no doubt, would be a little salt from time to time. Bone-meal is highly recommended.
