The pruning of nature is fortuitous. The tree has the irregularity and abandon of the picturesque. The pruning of man is for a different end, and it produces the comely well-proportioned tree of the orchards. The tree becomes a manipulated subject, comforting to the eye of the thrifty pomologist. Branch-pruning is essentially the removal of superfluous branches,--those that crowd, that cross each other, that are so placed as to be profitless, that are in the way, that are injured or diseased. For the most part, the branches should be removed when they are small; but it is not possible to foresee all that may be needed in the training of the tree and, therefore, the frequent advice to prune only with a hand-knife cannot be followed. One needs a sharp pruning-saw and sometimes a chisel on a long handle. Usually it is not necessary to remove branches more than an inch or one and one-half inch in diameter if pruning is carefully practiced every year; but sometimes even well-pruned trees must be shaped, corrected and improved by the cutting of larger branches. Pruning is usually best performed in early spring. The branch should be cut close to the main limb or trunk and parallel with it, leaving no stub; the healing process is then likely to proceed more rapidly. The wound should be smooth and clean, without breaks, splinters or splits; the knot-holes in logs and trunks are usually the consequence of long "stubs" and torn injured parts. The tree is to be left shapely, with a uniform distribution of branches, plenty of fruit-bearing wood, easy to spray and from which to pick the fruit, of the form characteristic of the variety. In all the usual customary pruning of the apple-tree, dressing of the wounds is not necessary. It is much more important to give the added attention to the proper making of the wounds and the thoughtful choice of the parts to be removed. Wounds two inches and more in diameter may be protected with good paint, so that they will not check and therefore not hold water, until the callus covers them. Good judgment in pruning is more profitable than recipes to repair damage. Fruit-pruning, or thinning, is the removing of so much fruit, when it is small, as will allow the remainder to mature to its best and constitute a maximum yield; it reduces the quantity of inferior fruit, lessens the number of culls and the labor at packing time, conserves the energy of the tree by preventing the maturity of great numbers of seeds, diminishes diseases and pests. The overloading of the tree not only imposes a heavy tax on its vitality but is likely to break the limbs and to work much physical damage. Thinning may consist in removing part of the fruit in the cluster (in the case of varieties that tend to mature more than one fruit from each flower-cluster), in picking all the fruits from certain clusters or pairs of clusters, or in cutting away some of the fruit-spurs before blossoming time.
