Pruning Apple Trees 3 When to Prune If you have a small orchard, delay pruning until it’s nearly spring. Allow for rain and bad weather, but plan to be finished pruning by May 1 or in time to begin spraying.

May 22, The best time to prune apple trees is either late in the winter or early in the spring because that’s the time when the tree is entering a dormant state after shedding its leaves and before new buds appear.
It’s best to complete the pruning just before the growth starts in the spring, so the cuts have time to heal quickly.
