Care Guide

Watering

Maintain consistent soil moisture during active growth to support bloom development

Fertilization

Apply a balanced slow-release fertilizer in early spring before new growth emerges. Do not over-fertilize, as excessive nitrogen can reduce flower production

Banana Peel Compost Tea:Compost banana peels for 2–3 weeks, steep in water for 24 hours, dilute 1:20 with water, and apply as a root drench to avoid leaf burn
Pruning
  • Remove dead, diseased, or crossing branches in late winter to improve air circulation
  • Thin overcrowded inner branches to promote light penetration and better bloom formation
  • Trim spent flower clusters in mid-summer to encourage a second bloom cycle
  • Avoid heavy "topping" pruning, as it can damage the tree's natural shape and reduce flowering
