Plant Needs
Sunlight
Bright indirect light; tolerates partial shade; avoid direct midday summer sun to prevent frond scorch
Watering
Water thoroughly when the top 5 cm of soil dries out; avoid overwatering to prevent root rot and caudex decay
Temperature

Care Guide
Watering
Keep soil slightly moist; reduce watering during periods of high humidity
Fertilization
Diluted balanced slow-release fertilizer once monthly. Use fertilizer with low nitrogen content to support caudex health
Eggshell powder topdress：Sprinkle finely ground, baked eggshells on soil surface; avoid direct contact with the caudex to prevent tissue damagePruning
- Remove brown, damaged fronds at the base to maintain rosette appearance
- Trim spent reproductive cones after maturity to redirect energy to new frond growth
- Avoid cutting into the underground caudex to prevent infection and waterlogging damage
