We have received numerous calls about pruning apple trees. I hope this article will help answer some of the questions.
Trees require different types of pruning as they age.
Young trees should be trained to encourage vigorous growth so the trees rapidly fill their spaces and are capable of producing heavy crops. Trees three to six years of age should be pruned and trained to encourage the transition from vegetative to reproductive growth.
Mature trees should be pruned to maintain an open canopy, to maintain adequate vigor to produce new fruiting wood and quality fruit, and to maintain tree size and shape. Fruit color, size and quality can also be improved with proper pruning.
Nonbearing trees: Pruning of young trees should be minimized to induce early fruiting. Removal of some scaffold limbs may be necessary to eliminate narrow crotches, excess limbs on one side of the tree and low limbs.
The first layer should consist of four or five limbs, the second and third layers should contain no more than four limbs and the top layer should contain no more than three limbs.
