Chinese Pistache Poor Fall Color: Fertilize for Vigor

Chinese Pistache Not Coloring Well? Boost Nutrition

Poor fall color in Chinese pistache often stems from nutrient deficiency, not genetics or nearby trees (mesquite has no effect).

Action

• Fertilize in spring with 10-10-10 at 1 lb/inch trunk diameter.
• Scatter from 1 ft out to drip line.
• Water in or apply before rain.

Why It Helps

Adequate nutrients → better chlorophyll breakdown and anthocyanin production → vibrant reds/oranges. Mesquite allelopathy is not a factor here.
