Of all fruit-trees, pruning is most used with the peach in regulating the development of the tree. In its early years, we may almost say that the peach "lives by the knife." At all stages of growth the vigorous use of the knife is indispensable in keeping the peach in proper bounds, and yet, rather paradoxically, knife and saw must be used sometime or other in the life of every peach-orchard to stimulate growth or at least to force out new growths. Indispensable as a certain amount of pruning is in training the peach, there is no question in the minds of those who have studied the subject but that it is much more often overdone than underdone. There are no fixed rules in pruning peaches and to discuss in full the diverse theories and practices is not within the range of this exposition. All that can be attempted is briefly to set down what the present practices are in the State. In transplanting, the peach suffers severe root-pruning, an operation that it does not bear well. Thus deprived of its roots, the young tree must have its top correspondingly diminished. Two practices are in vogue in New York in this curtailment of the top as the trees go from the nursery to the orchard. The most common practice is to cut the young tree back to a whip and then shorten-in the whip. New branches spring freely from this bare stub but these do not always come where they are wanted and often the new wood comes only from the stock. These objections to pruning to a whip have brought about a modification in which the branches are cut back to stubs of two or three buds. In a series of experiments now in progress on the Station grounds it seems certain that the second method is better than the first.
