When and How to Prune Trees in Fall Safely

Is Fall the Right Time to Prune?

While spring is generally preferred for most pruning, fall pruning is appropriate for removing dead, damaged, or diseased branches. Avoid heavy pruning as it can stimulate new growth vulnerable to frost.

What to Prune in Fall

Focus on deadwood, crossing branches, and any limbs that pose a safety hazard. Remove branches damaged by summer storms before winter winds cause them to break.

Tools You Need

Use hand pruners for branches up to three-quarter inch diameter, loppers for branches up to 2 inches, and a pruning saw for larger cuts. Always sharpen and clean tools before use.

The Three-Cut Method

For branches over 2 inches in diameter, use the three-cut method: first make an undercut about 12 inches from the trunk, then cut from above a few inches further out, and finally remove the stub just outside the branch collar.

Avoid Topping Trees

Topping creates weak, poorly attached regrowth and opens the tree to disease and pests. Instead, use selective pruning to reduce height gradually.

Winter Preparation

After pruning, apply 2 to 3 inches of mulch around the tree base to insulate roots over winter. Water deeply before the ground freezes.

• Only remove up to 25 percent of live branches per season
• Prune on dry days to reduce disease spread
• Disinfect tools between trees with rubbing alcohol
• Wait until trees are fully dormant for major cuts
