Care Guide
Watering
Maintain consistent moisture; mist fronds to boost ambient humidity
Fertilization
No regular fertilization required. Avoid fertilizing as it can cause frond browning and reduced vigor
Composted leaf mold tea：Steep fully composted leaf mold in water for 24 hours; dilute 1:20 for root drench to enrich soil humus content without over-fertilizingPruning
- Trim brown, dead fronds at the base in early spring to encourage new growth
- Remove damaged or yellowing fronds as needed to maintain a tidy clump
- Thin overcrowded clumps every 2–3 years to improve airflow and reduce disease risk
