Proper Pruning of a Storm-Damaged Magnolia Branch: Why Wound Paint Is Unnecessary

Correct Cut Technique

Make an undercut first to prevent bark tearing.
Cut through from the top, just outside the branch collar.
Leave a smooth surface flush with the trunk.

No Paint Needed

Research shows wound dressings (paint, tar, sealants) trap moisture and pathogens, slowing natural compartmentalization. The tree heals best when left alone.

Aftercare

Monitor for decay or pest activity, but no treatment is required unless problems develop.
