Care Guide

Watering

Water deeply every 7–10 days during dry periods to support growth and blooming

Fertilization

Apply a balanced slow-release fertilizer once to support new growth. Avoid over-fertilizing, as excessive nitrogen can reduce flowering

Banana Peel Compost Tea:Compost banana peels fully to break down nutrients; dilute 1:20 with water for root drenching to support foliage health and bloom production
Pruning
  • Remove dead, damaged, or crossing branches in late winter to maintain canopy shape and improve airflow
  • Thin dense inner branches to increase light penetration to lower foliage
  • Trim suckers growing from the base to focus growth on the main trunk and prevent overcrowding
