Care Guide

Watering

Maintain consistent soil moisture; increase watering frequency during prolonged dry spells

Fertilization

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

Composted banana peel tea:Steep fully composted banana peels in water for 24 hours; dilute the mixture 1:20 before applying as a root drench to support foliage and resin production
Pruning
  • Remove dead, diseased, or crossing branches in early spring to maintain canopy air circulation
  • Thin overcrowded growth to promote even light penetration throughout the canopy
  • Avoid heavy pruning, as it may reduce the tree's ability to produce balsam resin
