Stone Mulch Harms Trees: Heat Stress and Stunted Growth

Norm Mittleider, owner of The Art of Pruning (770-407-1511), read my comments on stone mulch.

He comments: "You couldn't have said it better. I've seen bad effects of stone mulch.

Case in point: poor Japanese maple in photo below. Monitored seven years. Result: very stressed tree with stunted growth. Summer heat effect intensified with DARK stones."
