Apply a balanced, slow-release palm fertilizer once at the start of growth. Avoid over-fertilizing, as this can cause frond tip burn
Eggshell powder topdressing：Crush dried, rinsed eggshells into a fine powder; sprinkle 1–2 tablespoons around the base of the plant every 6 months and water gently to incorporatePruning
- Wear thick, puncture-resistant gloves to avoid spine injury
- Remove brown, dead fronds at the base in early spring to improve airflow and appearance
