When is it best to prune an Oak tree?

• A. During the doormat season.
• B. Anytime.
• C. In winter.
• D. During the growing season.

Answer: (D)

Pruning while the tree is actively growing gives the plant plenty of energy to seal the wounds quickly. During the growing season, new callus tissue forms as cambial cells divide and sap flow is high, so cuts heal faster and are less likely to become entry points for problems. If you prune in winter when growth is dormant, wounds heal more slowly and the tree is less able to compartmentalize damage, leaving openings that can lead to decline or disease. So pruning during the growing season supports rapid recovery and maintains the tree’s vigor.
