Care Guide

Watering

Water deeply once weekly during extended dry spells to support new growth and flowering

Fertilization

Apply a balanced slow-release fertilizer in early spring to support new growth and flowering. Avoid over-fertilizing, as it can lead to excessive vegetative growth and reduced flowering

Banana Peel Compost Tea:Compost banana peels for 2–3 weeks to break down organic matter, steep in water for 24 hours, dilute 1:20 with water, and apply as a root drench to support foliage health and flowering
Pruning
  • Prune in late winter to remove crossing branches and maintain a balanced crown shape
  • Remove suckers growing from the base to prevent overcrowding and maintain tree structure
  • Trim dead or diseased branches promptly to reduce pest and disease risk
  • Avoid heavy pruning in summer, as it can stimulate tender new growth susceptible to frost damage
