Care Guide

Watering

Maintain consistently moist soil during active growth and fruiting

Fertilization

Apply a layer of well-rotted compost around the drip line. Avoid high-nitrogen fertilizers to prevent excessive foliage growth at the expense of fruiting

Banana Peel Compost Tea:Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 with water before applying as a root drench to avoid nutrient burn
Pruning
  • Remove dead, damaged, or crossing branches to improve canopy airflow and light penetration
  • Thin overcrowded growth to promote fruiting wood development
  • Prune young saplings to establish a strong central leader and desired canopy shape
  • Remove suckers at the base to direct energy to the main tree
