Improving Tree's Vigor Helps the Wound
USFS Illustation, Publication AIB-387
Improving a tree's health obviously helps if the tree trunk is injured. You might start by pruning dead and dying branches to increase tree vigor. Remove dead and fallen branches and trunks from the ground nearby. Such dead wood may harbor wood-inhabiting microorganisms that could infect wounds. Thin out and remove less valuable trees nearby to reduce competition for nourishment in favor of the wounded tree. Fertilize and water the tree properly to increase vigor.
