It may be frigid and cold outside with mounds of snow everywhere you look! But this is a great time to prune your apple trees to keep your tree healthy and produce a good harvest of good quality apples. In fact, did you know? Annual pruning is a crucial part of the care of an apple tree.

Why prune? 

Annie Klodd, UMN Extension Educator-Fruit and Vegetable Production: Pruning is essential for reliable fruit production from year to year. If left to their own devices, apple trees will develop dense canopies and many small fruit with uneven ripening, reduced quality, or generally lower productivity. Pruning focuses the tree’s energy into producing larger, higher quality apples and increases airflow through the tree, reducing disease potential.

How often should I prune an apple tree?

Apple trees should be pruned every year during dormancy. Early spring is a great time to prune, after the coldest winter temperatures have passed but before the trees break dormancy and bloom.

Step-by-step instructions

  1. Arborists warn against pruning too much crown at once. If memory serves me correctly, I believe the rule is not to prune more than 25% of a crown a year. Does this constraint also apply to apple trees?
