Care Guide
Watering
Keep soil evenly moist during active growth periods; avoid overwatering
Fertilization
Apply diluted slow-release fertilizer once every 2 months. Use a low-nitrogen, phosphorus-rich fertilizer to support healthy frond and cone development
Eggshell powder top-dressing：Grind dried, rinsed eggshells into a fine powder; sprinkle 1–2 tbsp around the base of the plant every 3 months to boost soil calcium levelsPruning
- Remove brown, dead fronds at the base to improve airflow and maintain a tidy appearance
- Trim damaged or yellowed leaflets from healthy fronds to reduce disease risk
- Remove spent cones after maturation to redirect energy toward new frond growth
