Care Notes
Light
Provide bright, filtered light. Direct sun scorches the delicate fronds quickly.
Water
Keep soil evenly moist, never waterlogged. Water when the surface feels only slightly dry. This fern does not like a bone-dry root ball. Use a pot with drainage holes.
Soil
A rich peat-based mix with perlite holds moisture while still draining.
Humidity & Temperature
Aim for 60% humidity or higher with a humidifier, pebble tray, or bathroom spot. Keep temperatures around 60-75°F and away from cold drafts and heating vents. In winter, keep humidity up even as growth slows.
Common Issues
Brown or yellow fronds can be removed at the base. Crispy tips usually mean dry air. Soft yellowing often means overwatering.
