Male Mulberry Vertical Cracks: Prune Deadwood, Time Cuts to Sap Slowdown

Male Mulberry

Male mulberry in Southern AZ has vertical trunk cracks. Arborist suggests thinning + deadwood removal. Owner asks: prune now or water first for crack healing? Best timing?

Recommendation

• Prune deadwood now—reduces weight, speeds recovery.
• Cracks heal naturally over time; extra water helps but don't overwater.
• Best timing: Wait until leaves start turning (fall) or late winter—sap flow slows, less "bleeding," easier healing.
• Cut dead branches to collar (no stubs); seal with pruning paint.

Plan: deadwood removal + paint within next few months; tree will thrive.
