Care Guide

Watering

Maintain consistently moist soil during active growth and fruiting seasons

Fertilization

Apply balanced slow-release fertilizer every 2 months. Avoid high-nitrogen fertilizers, which may reduce berry production

Banana peel compost tea:Soak fully composted banana peels in water for 24 hours; dilute the tea 1:20 with water before applying as a root drench to support fruiting
Pruning
  • Remove brown, dead fronds at the base to improve airflow and appearance.
  • Trim spent fruiting inflorescences after harvest to conserve the palm’s energy for new growth.
  • Avoid cutting the terminal growing bud, as it is essential for the palm’s vertical growth.
