Pruning is the most common tree maintenance procedure. Unlike forest trees, landscape trees need a higher level of care to maintain structural integrity and aesthetics. Pruning must be done with an understanding of tree biology because improper pruning can create lasting damage or shorten the tree’s life.

Most light, routine pruning to remove weak, dead, or diseased limbs can be accomplished at any time during the year with little effect on the tree.

As a rule, growth and wound closure are maximized if pruning takes place before the spring growth flush. Heavy pruning of live tissue just after the spring growth flush should be avoided, especially on weak trees.
