How to Properly Prune a Broken Tree Branch

Gravity is an unforgiving force, and a broken limb is more than just an eyesore—it is an open wound that invites disease and pests into your tree's vascular system. When a heavy storm or high wind shears a branch, the goal is to intervene cleanly, giving the tree the best possible chance to compartmentalize the damage and recover without secondary infections. Done well, a pruning cut respects the branch collar—the swollen area where the branch meets the trunk. By cutting just outside this collar, you avoid damaging the main trunk while providing a clean surface that the tree can successfully callus over. Avoid the amateur trap of cutting flush against the trunk, which removes the tree's natural healing tissue and creates a permanent entry point for decay.

1. Clear your workspace first. Identify the break point and clear debris from the ground beneath the limb. Ensure you have a stable footing before lifting any saws or loppers.
2. Support the branch from below. Measure about 6 to 12 inches away from the trunk. Make a shallow upward cut through the bottom of the branch, going about one-third of the way through.
3. Drop the excess weight. Move slightly further out on the branch, about an inch or two beyond your first cut. Saw completely through the branch from the top down to remove the majority of the weight.
4. Find the healing zone. Examine the remaining stub attached to the trunk. Identify the branch collar, which is the slightly raised, wrinkled swelling where the branch joins the parent stem.
5. Make the clean cut. Make your final cut just outside the branch collar, angling slightly away from the trunk. Use a sharp, clean hand saw to ensure a smooth, jagged-free surface.
6. Sterilize and let nature heal. Check the cut for clean edges and ensure there is no hanging bark or splintered wood. Clean your tools with rubbing alcohol to prevent spreading pathogens between trees.
