Optimal Pruning Times for Red Oak and Maple Trees

General Rule

Late winter/early spring (Feb–early Apr) before leaf-out.

Species-Specific

• Maples: Bleed heavily but harmless. Flow stops naturally.
• Oaks: Never prune April 1–July 1 (oak wilt risk via sap beetles). Best: Feb–Mar.

Avoid

• Spring leaf-out (low energy, bark tears).
• Fall leaf drop.

Key Takeaway

Prune oaks in Feb–Mar to prevent oak wilt. Maples can be pruned late winter despite bleeding.
