Davallia canariensis

Davallia canariensis, commonly known as the Hare's-foot fern, is a species of epiphytic fern belonging to the Davalliaceae family. It is native to the Canary Islands, Madeira, and parts of Southwestern Europe.

The plant is distinct for its rhizomes, which are covered in attractive, brown, scale-like hairs. These rhizomes creep along the soil surface and often cascade over the sides of the container, creating a unique ornamental display.

This crop requires filtered, indirect light to thrive. Intense sunlight can scorch the delicate foliage, making bright, shaded locations in a greenhouse or home environment ideal for optimal growth.

Climate requirements include a high ambient humidity level, preferably between 60% and 75%. If grown indoors, frequent misting or the use of a humidifier is essential to mimic its natural humid habitat.

The soil should be a well-draining, acidic medium composed of peat moss, perlite, and shredded pine bark. Proper aeration of the rooting zone is critical to support the epiphytic nature of this species.

The primary pests affecting Davallia canariensis are spider mites and mealybugs. Spider mites are particularly problematic during winter months when indoor heating lowers the air humidity.

Scale insects can attach themselves to the undersides of fronds and along the rhizomes, weakening the plant by extracting essential sap over time.

Fungal issues such as root rot typically occur due to poor drainage or overwatering. Maintaining a moist but never waterlogged root system is the best defense against fungal pathogens.

Physical damage to the sensitive rhizomes should be avoided, as these structures are vital for nutrient storage and the propagation of the fern.

To ensure plant health, utilize a balanced, diluted liquid fertilizer during the growing season and remove any dead or yellowing fronds to prevent the spread of opportunistic fungi.
