Care Guide

Watering

Maintain consistent soil moisture; apply mulch to retain water and regulate soil temperature

Fertilization

Apply balanced slow-release fertilizer once every 2 months. Avoid high-nitrogen fertilizers to prevent excessive foliage growth at the expense of flowers

Banana peel compost tea:Fully compost banana peels, steep in water for 3 days, dilute 1:20 for root drench to support flower and fruit development; avoid applying undiluted compost to prevent root burn
Pruning
  • Remove dead or damaged branches annually in early spring to maintain canopy health
  • Trim overgrown branches to control tree size and shape, taking care not to remove flowering wood
  • Remove persistent spent fruit capsules if desired to reduce excess branch weight and improve aesthetic appearance
