Sago Palm Yellowing in South African Heat: Soil Drainage and Nutrition

The Case

Sago palm near Cape Town: fronds yellow/curl 2–4 weeks after new growth. High heat, little rain.

Assessment

Sagos love heat but need fast‑draining, sandy soil. Symptoms suggest waterlogged clay or nutrient imbalance, not infectious disease.

Checks

• Soil drainage—amend with sand/grit if heavy.
• Inspect for scale insects on leaves.
• Fertilize with balanced palm formula.
