Christmas Fern Plant Care

Christmas Fern (Polystichum acrostichoides) belongs to the Dryopteridaceae family within the Polystichum genus. Christmas Fern is native to eastern North America, from Nova Scotia west to Minnesota and south to Florida and eastern Texas. Christmas Fern is also known as Eastern Christmas Fern.

Christmas Fern displays a clumping fern growth habit, reaching up to 2 inches tall with a spread of approximately 2 inches. Christmas Fern produces non-flowering.

Leaf size: approximately 18 inches.

Polystichum acrostichoides 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.

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

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

Moist, well-draining soil rich in organic matter. Good drainage is essential for Christmas Fern to prevent waterlogging, which leads to root rot and fungal issues.

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

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

Christmas 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.

Christmas Fern grows outdoors in USDA Zone 3a – 8b. Native to eastern North America, from Nova Scotia west to Minnesota and south to Florida and eastern Texas, Christmas Fern is adapted to warm climates. In cooler regions, grow Christmas Fern as a houseplant or bring it indoors before the first frost.
