Davallia mariesii, the squirrel's foot fern, is a species of epiphytic fern native to Japan and eastern Asia. It is deciduous, growing to 15 cm (6 in), with rhizomes covered in brown scales and finely-dissected, flat, triangular fronds. If provided with winter protection, it is hardy down to −7 °C (19 °F). In cultivation it is used as groundcover in moist, shady areas.This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Squirrel's-Foot Fern typically shows strong resistance to disease and is affected by relatively few insect pests. Its care is regarded as difficult because it needs consistently moist conditions and regular watering. At the same time, its roots can rot if it is watered too much or if the surrounding air is poorly ventilated. This fern is best for people who have some experience growing plants, since most caretakers can keep it alive for a while. Even so, Squirrel's-Foot Fern can struggle to thrive, and over time its fronds may dry out and lose vigor.
How to keep Davallia Mariesii.
Light
Squirrel's-Foot Fern performs best with moderate sunlight and can tolerate both abundant and scarce light conditions. It was originally found in habitats characterized by varying light intensity and adapts well to different light environments. Excessive or insufficient light exposure can affect its growth, though the impact is not severe.
Temperature
The Squirrel's-Foot Fern needs warm conditions to thrive; its native growing environment ranges from 68 to 86℉ (20 to 30℃). Generally, it prefers temperatures between 68 and 100℉ (20 to 38℃). In colder months, it is recommended to move the plant to a warmer location or use a heating pad to keep it within its preferred temperature range.
Pot & Repot
When repotting a Squirrel's-Foot Fern, select a pot 1–2 inches (2.5–5.1 cm) larger with good drainage. Use a well-draining potting mix. Repot in spring or fall, making sure the root ball sits just below the rim of the pot. Water thoroughly after repotting and place the fern in a warm spot with indirect sunlight.
