Watering

Increase watering during prolonged dry spells to maintain consistent soil moisture

Fertilization

Apply a balanced slow-release granular fertilizer once. Avoid over-fertilizing, as excessive nitrogen can reduce wood density and quality

Composted banana peel tea:Compost banana peels for 2–3 weeks to break down organic matter; steep in water for 24 hours, dilute 1:20 with water for root drenching to avoid nutrient burn
Pruning
  • Remove dead, diseased, or crossing branches in late winter to improve canopy airflow
  • Thin crowded inner branches to increase light penetration to lower foliage
  • Prune to maintain a desired canopy shape; avoid heavy pruning of mature trees to prevent stress
