Care Guide

Watering

Water deeply once weekly during active growth to support frond development

Fertilization

Apply slow-release palm fertilizer once to support new growth. Avoid high-nitrogen fertilizers that can cause frond tip burn

Eggshell powder top-dressing:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of the palm every 6 months to boost soil calcium levels
Pruning
  • Remove dead, brown fronds at the base to improve airflow and reduce pest habitat
  • Trim spiny petiole stubs only if they pose a safety hazard to humans or pets
  • Avoid over-pruning healthy fronds, as they provide essential nutrients to the palm during dormant periods
