Blue Star Fern Plant Care

Blue Star Fern (Polypodium aureum) belongs to the Polypodiaceae family within the Polypodium genus. Blue Star Fern is native to tropical and subtropical regions of the Americas. Blue Star Fern is also known as Rabbit's Foot Fern, Hare's Foot Fern, Bear's Paw Fern.

Blue Star Fern displays a low rosette, spreading growth habit, reaching up to 0.5 inches tall with a spread of approximately 1.5 inches. Blue Star Fern produces non-flowering.

Leaf size: approximately 12 inches.

Polypodium aureum 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.

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

Polypodium aureum grows best at temperatures between 60°F and 75°F. Blue Star Fern prefers humidity levels of 50–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Loose, well-draining soil mix with high organic content. Good drainage is essential for Blue Star Fern to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 1-2 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.

Blue Star Fern can be propagated through spores, division of rhizomes.

Blue Star 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.

Blue Star Fern grows outdoors in USDA Zone 9b – 11b. Native to tropical and subtropical regions of the Americas, Blue Star Fern is adapted to warm climates. In cooler regions, grow Blue Star Fern as a houseplant or bring it indoors before the first frost.
