There are many pruning techniques involved with fruit trees, however, the general idea is to train the tree to have an open, spreading framework as to allow the most amount of light to enter the crown as possible. This can be accomplished by pruning out some of the central leaders as well as by tying down some of the upright branches so they are horizontal. Concerning fruit trees with multiple grafts, (i.e., 4 in 1), extra care must be taken so that the most vigorous of the grafts does not take over the weaker ones. All pruning on branches should be done when plants are dormant, with a downward slant cut going down ¼” from the bud. Fruit thinning may be necessary for young trees or varieties prone to overbearing. This may only be accomplished by manual removal of the immature fruit shortly after flowering.
