Soil Testing for Struggling Chinese Pistache

Chinese pistache planted May 2010 struggles: pale leaves, yellowing, sparse growth. Photos show thinning canopy.

Soil-Related Diagnosis

Leaf color and poor growth suggest nutrient imbalance, pH issue, or drainage problem—not a primary pest/disease.

Soil test: Contact county Extension for free/low-cost analysis. Correct per recommendations.
Inspect trunk base: Check for bark damage, mechanical injury, or girdling roots.
Assess drainage: Ensure no water pooling at root zone.

Addressing soil conditions is the most productive path for this species.
