Care Guide

Watering

Fertilization

Apply balanced, slow-release fertilizer once monthly. Avoid over-fertilizing, as excessive nitrogen can reduce fruiting potential.

Banana peel compost tea:Soak fully composted banana peels in water for 24 hours; dilute the mixture 1:20 with water before applying as a root drench to avoid nutrient burn.
Pruning
  • Remove dead, diseased, or crossing branches in late winter to improve air circulation.
  • Thin overcrowded canopy growth to increase sunlight penetration for better fruiting.
  • Prune container-grown specimens to maintain a manageable height and shape in early spring.
