Care Guide
Light Requirements
Place in bright, filtered light. Avoid direct afternoon sun which can scorch the delicate fronds. Low light may slow growth.
Watering
Keep the soil consistently moist but not waterlogged. Water when the top of the soil feels slightly dry to the touch. Do not allow the root ball to dry out completely.
Humidity
Thrives in high humidity environments (50% or higher). Use a humidifier, pebble tray, or place in a naturally humid room like a bathroom.
Seasonal Care
In winter, reduce watering slightly as growth slows, but ensure the air remains humid if heaters are in use.
Common Issues
Yellowing fronds often indicate overwatering, while crispy, brown edges usually signal low humidity or underwatering.
