Care Guide

Watering

Keep soil evenly moist; add mulch around the base to retain moisture and regulate soil temperature

Fertilization

Apply balanced slow-release fertilizer every 2 months to support new growth and fruiting. Avoid over-fertilizing to prevent excessive leaf growth at the expense of fruiting

Banana peel compost tea:Use fully composted banana peels, dilute 1:20 with water for root drenching; avoid raw peels to prevent pest infestations and odor buildup
Pruning
  • Remove dead, diseased, or crossing branches in late winter to improve airflow and sunlight penetration.
  • Thin overcrowded branches to encourage better fruiting on older wood.
  • Prune to maintain desired height and shape, especially for container-grown specimens.
