Japanese Maple Pruning Shock: Light Reduction and Water Competition

Pacific NW Coral Bark Japanese Maple (planted last year) pruned longer branches on one side. 1-2 weeks later all leaves crispy dead. Vinca ground cover at base healthy.

Two Factors

Pruning shock: Cut back light-seeking growth → sudden energy loss.
Water competition: Vinca likely taking most water; maple dehydrated.

Rescue Attempt

Water 1 inch every 3 days for a month (pan/sprinkler). May recover if roots alive.
