Q&A - Should I use a pruning sealant?

Question:
Should I use a sealant when pruning trees in my yard?

Answer:
Pruning sealants should  not be used. Trees naturally create a barrier between damaged tissue (the cut) and healthy tissue. Pruning sealants can hold moisture and cause fungal diseases or rot to get into the tree.
