Care Guide

Watering

Composted banana peel tea:Compost banana peels for 4–6 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 healthy foliage growth
Pruning

  • Trim overcrowded lower branches to improve airflow and light penetration
  • Avoid heavy pruning, as coniferous growth has limited regrowth potential
