Autumn Fern Plant Care

Autumn Fern (Dryopteris erythrosora) belongs to the Dryopteridaceae family within the Dryopteris genus. Autumn Fern is native to China South-Central, China Southeast, Japan, Korea, Nansei-shoto and Taiwan. Autumn Fern is also known as Rose Fern.

Autumn Fern displays a fern with spreading habit growth habit, reaching up to 2 inches tall with a spread of approximately 3 inches. Autumn Fern produces non-flowering plant.

Leaf size: approximately 18 inches.

Dryopteris erythrosora requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Autumn Fern thrives in filtered sunlight or partial shade light conditions. The optimal light range is 100–500 lux. Avoid placing Autumn Fern in direct, harsh sunlight for extended periods, as this can scorch the foliage.

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

Rich, well-draining soil with high organic matter content. Good drainage is essential for Autumn 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.

Autumn Fern can be propagated through spores, division of rhizomes.

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

Autumn Fern grows outdoors in USDA Zone 6a – 8b. Native to China South-Central, China Southeast, Japan, Korea, Nansei-shoto and Taiwan, Autumn Fern is adapted to warm climates. In cooler regions, grow Autumn Fern as a houseplant or bring it indoors before the first frost.
