Crocodile Fern
Microsorum musifolium 'Crocodyllus'
The Crocodile Fern is a unique and captivating epiphytic plant originating from Southeast Asia. Its most striking feature is the intricate, scale-like pattern of its dark green veins against the bright green, glossy fronds, which resembles crocodile skin. Give it bright, indirect light, higher humidity, and steady moisture in a planter with drainage holes.

Care Notes
Water
Keep the soil consistently moist but never waterlogged. Allow the top inch of soil to dry out slightly before watering again. Using a pot with drainage holes is essential to prevent root rot.
Light
This fern thrives in bright, indirect light. Avoid direct afternoon sun, which can scorch the leathery fronds. It can tolerate medium light conditions, though growth will slow down.
Humidity and Temperature
& Temperature
Maintaining high humidity (60% or higher) is key to keeping the fronds lush. Use a humidifier or a pebble tray if your indoor air is dry. Keep the plant in temperatures between 65°F and 80°F (18°C - 27°C) and avoid cold drafts.
Common Issues
If the leaf tips turn brown, it is likely due to low humidity or hard water. Yellowing leaves may indicate overwatering or poor drainage.
Seasonal Care
In winter, reduce watering frequency as the plant’s growth slows, but continue to maintain high humidity levels.
Soil and Planter
Use a rich, well-draining potting mix such as a blend of peat moss or coco coir with perlite or orchid bark. Choose a planter with drainage holes so excess water can escape.
