The short answer

Most deciduous trees are best pruned while dormant, in late winter before buds swell — you can see the branch structure and cuts close quickly in spring. Remove dead, damaged and crossing branches first, cut just outside the branch collar, and use the three-cut method on anything heavier than you can hold. Spring-flowering trees are the exception: prune them right after they bloom.

What to cut, in order

  1. 1Dead, broken or diseased wood.
  2. 2Branches rubbing or crossing another branch.
  3. 3Branches growing back toward the trunk or straight down.
  4. 4Low limbs over walkways, the roof or the driveway.
  5. 5Light thinning only — remove no more than about a quarter of the canopy in a year.

The three-cut method for heavy limbs

  1. 1Undercut about a foot out from the trunk, a third of the way through.
  2. 2Top cut a little farther out; the limb drops without tearing bark.
  3. 3Final cut just outside the branch collar — don't cut flush to the trunk.

Frequently Asked Questions

Is it bad to prune trees in fall?
Fall cuts heal slowly and some fungi spread spores then. Late winter is usually better.
Should I seal pruning cuts?
Generally no. A clean cut outside the collar closes on its own; wound paint can trap moisture.
When should I prune oaks?
In regions with oak wilt, prune only in the dormant season and follow local guidance.
