Care Guide

Watering

Keep soil consistently moist during active growth and fruiting periods

Fertilization

Apply balanced liquid fertilizer monthly to support new growth. Avoid over-fertilizing, as this can reduce flowering and fruiting.

Banana peel compost tea:Compost banana peels for 2 weeks, steep in water for 24 hours, dilute 1:10 with water before applying as a root drench; avoid using uncomposted peels to prevent pest infestations.
Pruning
  • Prune dead, diseased, or crossing branches in late winter to stimulate new, productive growth.
  • Thin overcrowded stems to improve air circulation and increase sunlight penetration for better fruiting.
  • Pinch back young shoots to promote a bushier, more compact growth habit and prevent leggy growth.
