Liquidambar Suckers (Epicormic Shoots): Prune in Dormancy

Removing Lower Trunk Sprouts on Liquidambar

Sprouts on lower trunks are epicormic shoots—dormant buds activated by increased light (nearby tree removal, heavy pruning).

Proper Removal

• Timing: Late fall/winter (dormant season). Pruning in growth season stimulates more sprouts.
• Method:
  • Large suckers: Two-cut method (undercut, then top cut) to avoid bark tearing. Final cut at 45° outside branch collar.
  • Small suckers (<½"): One cut at 45° outside collar.
• Limit: Remove lower 1/3 to 1/2 of trunk sprouts. Don't over-thin.

Why Dormant Pruning?

Prevents flush of new sprouts from pruning wounds. The tree's energy is in roots, not active growth.
