Care Guide

Watering

Water deeply when the top 2 cm of soil feels dry to maintain consistent moisture

Fertilization

Apply balanced, diluted liquid fertilizer every 2 weeks. Reduce fertilization to once monthly in autumn and discontinue entirely in winter when growth slows.

Banana Peel Tea:Chop 2–3 banana peels and soak in 1 gallon of water for 3 days; strain and dilute the solution 1:2 with water before applying as a root drench to avoid nutrient burn.
Pruning
  • Remove yellowing or damaged leaves at the base of the petiole to improve airflow and reduce pest risk.
  • Trim suckers that grow from the base of the trunk to maintain a single, dominant stem for optimal fruiting.
  • Cut back overgrown petioles to prevent crowding; avoid cutting the main trunk as it does not branch naturally.
