The Davallia fejeensis, commonly known as the Squirrel Foot Fern or Rabbit’s Foot Fern, is a captivating houseplant admired for its unique appearance. This fern is native to the Fiji Islands and other South Pacific regions, where it grows as an epiphyte, attaching itself to trees and rocks rather than rooting in the soil. Its most distinctive feature is the furry, creeping rhizomes that grow on the soil surface and often cascade over the edges of its pot, resembling a squirrel’s or rabbit’s foot. These ornamental rhizomes are covered in fine, rust-colored hairs, adding to its visual appeal.
Squirrel Foot Fern Care
Light
Squirrel Foot Ferns thrive in environments that offer bright, indirect light. In their natural habitat, they receive filtered sunlight beneath larger plant canopies. A north or east-facing window provides suitable gentle light without harsh direct exposure. Direct sunlight can scorch the delicate fronds, leading to browning and damage.
Watering
Consistent moisture is important for the Squirrel Foot Fern, yet it is susceptible to root rot if overwatered. The soil should be kept consistently moist but not waterlogged, allowing the top inch to dry out slightly between waterings. Using lukewarm water prevents shocking the plant, and adequate drainage holes are important. Avoid watering the fuzzy rhizomes directly, as this can lead to rot; instead, water the soil.
Humidity
As a tropical plant, the Squirrel Foot Fern requires high humidity (ideally 50-80%) to flourish. Low humidity can cause the frond tips to brown and crisp, indicating a need for increased moisture in the air. Practical methods to boost humidity include:
Placing the pot on a pebble tray filled with water.
Misting the fronds and exposed rhizomes regularly.
Using a room humidifier.
Grouping the fern with other plants to create a beneficial microclimate.
Soil and Potting
An ideal soil mix for Squirrel Foot Ferns is well-draining, airy, and rich in organic matter. A peat-based potting mix, often combined with perlite or orchid bark, works well to provide both drainage and moisture retention. The preferred pH range is slightly acidic to neutral (6.0-7.0).
Temperature
Squirrel Foot Ferns prefer warm, consistent temperatures for optimal growth. The ideal temperature range is 60-75°F (15-24°C) during the day. Temperatures should not drop below 55°F (13°C) at night, as the plant cannot tolerate cold conditions. Protecting the fern from sudden temperature fluctuations and cold drafts is important for its health.
Fertilizing
During its active growing season (spring through summer), the Squirrel Foot Fern benefits from light fertilization. A balanced, liquid fertilizer diluted to half strength should be applied about once a month. Over-fertilizing can lead to a buildup of salts in the soil, potentially harming the plant. It is best to avoid fertilizing during the fall and winter months when the plant’s growth naturally slows.
Repotting Squirrel Foot Fern
Repotting is needed every two to three years or when the fern outgrows its container. Indicators such as roots emerging from drainage holes, stunted growth, or the soil drying out quickly after watering suggest it is time for a larger pot. When repotting, select a new pot that is only slightly larger than the current one, perhaps one to two inches wider, to prevent excess moisture retention.
Carefully remove the fern from its old pot, avoiding damage to delicate rhizomes. Place fresh, well-draining potting mix in the new pot, positioning the fern so its fuzzy rhizomes sit on or just below the soil surface. Burying the rhizomes can lead to rot, as they are designed to absorb moisture from the air. After repotting, water the plant thoroughly and place it in a shaded area for a few days to help it recover from the transition.
Propagating Squirrel Foot Fern
Propagating Squirrel Foot Ferns is primarily achieved by dividing their rhizomes. This method is most effective during the spring or early summer when the plant is actively growing. Begin by gently removing the mature fern from its pot, being cautious not to harm the rhizomes or roots.
Carefully separate a section of the rhizome that has at least one or two fronds attached. A clean, sharp knife or scissors can be used to make the cut if natural divisions are not apparent. Plant each separated rhizome section in its own pot, ensuring the rhizome rests on the surface of the potting mix, not buried. Water the newly potted divisions lightly and provide them with a warm, humid environment with indirect light to encourage new growth.
Common Issues and Solutions
Squirrel Foot Ferns can exhibit several common issues, often related to their environmental conditions. Browning frond tips often signal low humidity or underwatering. Increasing ambient humidity through misting or pebble trays, and adjusting watering frequency to keep the soil consistently moist, can help resolve this. Yellowing leaves may indicate overwatering, insufficient light, or nutrient deficiencies. Allowing the topsoil to dry before rewatering, ensuring adequate indirect light, and providing diluted fertilizer during the growing season can address these concerns.
While resistant, Squirrel Foot Ferns can encounter pests like spider mites, mealybugs, and scale insects. Regular inspection of the fronds and rhizomes can help detect infestations early. For minor issues, manual removal with a cotton swab dipped in rubbing alcohol can be effective, or insecticidal soap and neem oil can be used for more widespread problems. Promoting good air circulation around the plant also helps prevent fungal issues like leaf spot.
