Tree Wound Dressings: Skip the Sealant, Let Nature Heal

Research shows wound paints (tar, Lac Balsam, etc.) hinder a tree's natural compartmentalization, eventually cracking and trapping moisture. For a large white oak wound:

Trim loose bark cleanly.
Optional: spray gray paint to camouflage.
Let the tree seal it naturally.

If a tree company caused the damage, hire an ISA consulting arborist to appraise value loss for an insurance claim.
