Pruning Deciduous Shrubs in Autumn: When and How

By Marcus Williams · October 6, 2026

Timing Matters

Most deciduous shrubs should be pruned in late winter or early spring, not fall. Fall pruning can stimulate new growth killed by frost, and wounds heal slower in cool weather.

What You CAN Prune in Fall

Dead or diseased wood: Remove anytime to prevent spread
Crossing branches: Remove to prevent bark damage
Summer-flowering shrubs: Light shaping after leaf drop

Proper Technique

Make clean cuts at 45-degree angles, 1/4 inch above a bud. Use sharp bypass pruners for branches under 1/2 inch and loppers for larger cuts.

What NOT to Prune in Fall

Spring-blooming shrubs (forsythia, lilac, azalea) set buds now. Pruning removes next years flowers. Wait until after spring bloom.

Tool Care

Clean pruners with rubbing alcohol between cuts on diseased wood. Oil pivot points and sharpen blades before winter storage.
