Care Guide

Watering

Keep soil consistently moist but not waterlogged during active growth

Fertilization

Apply balanced organic fertilizer once monthly. Avoid high-nitrogen fertilizers, which can promote excessive foliage growth at the expense of flowering and fruiting

Composted banana peel tea:Steep fully composted banana peels in water for 24 hours, dilute 1:20, and apply as a root drench to support flowering and fruiting
Pruning
  • Remove dead, damaged, or crossing branches in early spring to maintain canopy airflow
  • Shape young trees lightly to encourage a rounded, open canopy form
  • Avoid heavy pruning, as the slow-growing tree recovers gradually from major cuts
