Crocodile Fern Plant Care

Crocodile Fern (Microsorum musifolium) belongs to the Polypodiaceae family within the Microsorum genus. Crocodile Fern is also known as Kangaroo Fern, Banana Fern.

Crocodile Fern displays a low rosette, spreading growth habit, reaching up to 1.5 inches tall with a spread of approximately 2 inches. Crocodile Fern produces non-flowering.

Leaf size: approximately 12 inches.

Microsorum musifolium requires watering every 7–10 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Crocodile Fern thrives in bright indirect to low light light conditions. The optimal light range is 100–500 lux. Avoid placing Crocodile Fern in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Microsorum musifolium grows best at temperatures between 60°F and 75°F. Crocodile Fern prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, peat-based potting mix with added perlite for aeration. Good drainage is essential for Crocodile Fern to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Crocodile Fern can be propagated through spores, division of rhizomes. Similar propagation techniques also apply to kangaroo fern plant care, which shares the same genus.

Crocodile Fern is susceptible to spider mites, scale insects. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Crocodile Fern grows outdoors in USDA Zone 10b – 12b. In cooler regions, grow Crocodile Fern as a houseplant or bring it indoors before the first frost.
