Rather, the tree should be left to heal through its own devices after you prune it.

In this manner, should I seal a tree wound?

In most cases, it is best to simply let wounds seal on their own. Instead, they compartmentalize wounds with layers of cells that prevent damage from spreading any further. A properly pruned tree or shrub will seal off wounds and prevent decay organisms from entering the trunk.

How do you seal a branch after cutting?
