Davallia tyermanii, the bear's foot fern or white rabbit's foot fern, is a species of fern in the family Davalliaceae, native to northern Myanmar, southern China, and Taiwan. A rhizomatous epiphyte or lithophyte reaching 0.5 m, it is typically found in the subtropics. Under its synonym Humata tyermanii it has gained the Royal Horticultural Society's Award of Garden Merit. It is available from commercial suppliers, and requires full sun.
White rabbits foot fern typically shows good resistance to disease and is affected by relatively few insect pests. Its care is considered difficult because it needs a moist environment and frequent watering. The roots, however, are susceptible to rot if overwatered or if the surroundings lack good ventilation. White rabbits foot fern is suitable for people with some growing experience, as most can keep it alive for a period of time. Nonetheless, it may struggle to thrive and its leaves can dry out and become less healthy over time.
How to keep Davallia Tyermannii.
Light
White rabbits foot fern is native to habitats such as forest understories and rocky locations where natural shade occurs. It prefers full shade but can tolerate partial sun.
Water
The White Rabbit's Foot Fern thrives in humid conditions and benefits from consistent moisture, although it also has a moderate tolerance for drought. To keep its foliage healthy, it's best to water it twice a week. Usually grown indoors, this fern flourishes in well-draining soil that mimics its natural, airy habitat.
Temperature
White rabbits foot fern is fairly adaptable to temperature, able to endure high heat and wide temperature fluctuations. In hot weather, you should pay attention to watering and provide suitable shade to avoid sunburn. However, White rabbits foot fern is relatively sensitive to low temperatures. Although it can tolerate some chill, very cold conditions can cause frost damage.
Pruning
To encourage new growth and improve the appearance of your white rabbit's foot fern, prune it in early spring by removing any dead or yellowing fronds. Be careful not to over-prune, as this can stress the plant. Maintaining good airflow and light is also important. Pruning at this time takes advantage of the fern's natural growth cycle, helping it thrive during the growing season.
Pot & Repot
When repotting White rabbits foot fern, select a pot 1-2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, ensuring the root ball sits slightly below the rim of the flower pot. Water thoroughly after repotting and place it in a warm spot with indirect sunlight.
