Care Guide

Watering

Increase watering to keep soil consistently moist during active growth

Fertilization

Diluted balanced palm fertilizer every 4 weeks. Avoid over-fertilizing to prevent salt buildup in soil

Banana peel compost tea:Compost banana peels for 2–3 weeks; steep in water for 24 hours, dilute 1:20 for root drench; avoid raw peels to prevent pest infestations and odor
Pruning
  • Remove brown, dead fronds to maintain appearance and improve airflow
  • Trim spent flower stalks after fruiting to reduce unnecessary nutrient drain
  • Avoid cutting green fronds as they provide photosynthetic energy for the palm
  • Thin overcrowded lower fronds to improve light penetration to the trunk base
