Stressed Japanese Maple: Selective Pruning and Sunscald Protection

Wait Until Early May

Don't prune yet. By early May, living wood will leaf out. Then:

Remove dead wood back to healthy tissue.
Protect trunk from sunscald: Build stake frame, drape old bedsheet or shade cloth over canopy.

Defoliated trunk bark burns in full sun. Shade cloth mimics the missing canopy until new leaves regrow—may take 3 years.

If recovery is sparse after 2–3 years, consider replacement. A struggling specimen may never regain its grace.
