If not done yet, renovate overgrown shrubs including redtwig dogwood, lilac, and forsythia by removing one-third of the oldest canes.
Prune out all ground-level sucker growth from crabapple, apple, plum, peach or apricot trees by cutting out growth below soil level.
Prune out weak, green but very fast-growing water sprouts that grow vertically from branches of fruit trees, redbuds, or other ornamental flowering trees.
If necessary, boxwood and yews can be lightly pruned to maintain geometric form. Avoid overpruning, especially in very sunny, hot weather.
