Loquat Tree Care: Yellow Leaves Mean Overwatering—Fix Drainage and Mulch Deep

Loquats (Eriobotrya japonica) are drought-tolerant once established. Yellow/dark leaves on the hand-watered tree (vs. drip-irrigated neighbors) = classic overwatering.

Diagnosis

• Wet soil surface daily → roots suffocate.
• Yellowing older leaves + new green growth = stress response, not death.
• Drip-irrigated trees fine because water penetrates deeply, infrequently.

Correct Watering Regime

• Established trees: Deep soak every 2 weeks.
• Deep mulch (6–18"): Wood chips, straw, leaves — retains moisture between waterings.
• New plantings: Frequent watering first 3–6 months, then transition.

Additional Care

• Soil: Any type with excellent drainage.
• Fertilizer: Light N (1–3×/yr); excess reduces flowering.
• Pruning: After harvest; thin canopy for light penetration → more fruit.
• Timing: Prune after frost danger, before spring bud break.

Key Insight

Loquats want deep, infrequent water and perfect drainage. The hand-watered tree is drowning. Switch to deep soaks + thick mulch. It will recover.
