Care Guide

Watering

Maintain consistent soil moisture during active growth periods to support canopy expansion

Fertilization

Apply a balanced slow-release fertilizer once at the start of the growing season. Avoid high-nitrogen fertilizers, which can promote excessive leaf growth at the expense of wood development

Composted banana peel tea:Soak fully composted banana peels in water for 3 days, dilute the mixture 1:20 with water, and apply as a root drench; discard solid peels to avoid attracting pests or causing soil odor
Pruning
  • Remove dead, diseased, or crossing branches in late winter to improve canopy airflow and structure
  • Thin crowded upper branches to allow light penetration to inner foliage and promote uniform growth
  • Trim lower branches of young saplings to encourage upright trunk development and clear canopy space
