Most of you are scared to death of pruning and rightly so. That's because you do it wrong. Have no fear, the Grump in his great beneficence will reveal the path to pruning enlightenment.

When you prune is very important, especially when dealing with flowering trees and shrubs. Prune them at the wrong time and you'll cut off the flower buds and they won't bloom. So before you cut anything, know whether it blooms and when. Prune spring-flowering trees and shrubs immediately after they finish blooming. Prune summer- and fall-flowering trees and shrubs in late winter, before they begin the current season's growth. If in doubt, you can never go wrong by pruning a flowering plant right after its final blooms fade.

What about trees and shrubs that don't bloom? When should you prune those? With a few exceptions (noted below), now is a good time. I especially like pruning deciduous trees now, because with the leaves off, you can easily see what needs to be removed.
