Care Guide

Watering

Keep soil consistently moist during active growth and fruiting

Fertilization

Apply balanced slow-release fertilizer every 4 weeks. Avoid over-fertilizing 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, and apply as a root drench to avoid soil odor and pest issues
Pruning
  • Prune in late winter to remove dead, diseased, or crossing branches and maintain a compact shape
  • Thin crowded inner branches to improve airflow and light penetration for better fruiting
  • Pinch back young shoots on container plants to encourage bushier growth
