Elkhorn Fern Plant Care

Elkhorn Fern (Platycerium superbum) belongs to the Polypodiaceae family within the Platycerium genus. Elkhorn Fern is native to Australia. Elkhorn Fern is also known as Staghorn Fern.

Elkhorn Fern displays an epiphytic, fern-like growth habit, reaching up to 2 inches tall with a spread of approximately 3 inches. Elkhorn Fern produces non-flowering.

Leaf size: approximately 24 inches.

Platycerium superbum 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.

Elkhorn Fern thrives in bright indirect to dappled shade light conditions. The optimal light range is 150–400 lux. Avoid placing Elkhorn Fern in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Platycerium superbum grows best at temperatures between 60°F and 80°F. Elkhorn Fern prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining epiphytic mix with sphagnum moss and bark chips. Good drainage is essential for Elkhorn Fern to prevent waterlogging, which leads to root rot and fungal issues.

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

Elkhorn Fern can be propagated through spores, division of offsets (pups). Similar propagation techniques also apply to staghorn fern plant care, which shares the same genus.

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

Elkhorn Fern grows outdoors in USDA Zone 10b – 12. Native to Australia, Elkhorn Fern is adapted to warm climates. In cooler regions, grow Elkhorn Fern as a houseplant or bring it indoors before the first frost.
