The Davallia fejeensis, commonly known as the Rabbit Foot Fern, is a distinctive houseplant. It is admired for its delicate, lacy fronds and fuzzy, foot-like rhizomes.
Native to the South Pacific, this epiphytic fern naturally grows on trees or in rock crevices, absorbing moisture and nutrients from the air. Its straightforward care makes it a popular choice for indoor gardeners.
Rabbit Foot Fern Care
Rabbit Foot Ferns thrive in environments mimicking their native tropical habitat. Consistent conditions for light, water, humidity, soil, and nutrients are essential for a healthy plant.
Light
Rabbit Foot Ferns prefer bright, indirect light, similar to dappled sunlight under a forest canopy. A north or east-facing window is ideal, providing ample light without harsh direct sun. Direct sunlight can scorch delicate fronds, leading to browning or discoloration. Consistent, filtered light promotes optimal growth.
Watering
Maintain consistent soil moisture for Rabbit Foot Ferns, avoiding waterlogging. Water thoroughly until it drains from the pot’s bottom, then allow the top inch of soil to dry before rewatering. Water the furry rhizomes directly, as these structures absorb moisture and nutrients. Reduce watering frequency during the plant’s semi-dormant winter period.
Humidity
High humidity is important for Rabbit Foot Ferns, which thrive in levels between 60% and 70%. To increase humidity, regularly mist fronds and rhizomes, place the pot on a pebble tray, or use a room humidifier. Adequate humidity prevents rhizome drying and keeps frond tips from browning.
Soil
A well-draining, airy potting mix is suitable for these ferns, allowing for aeration while retaining moisture. A fern-specific blend, often containing peat moss, perlite, and orchid bark, works well. This mix prevents soil compaction and ensures roots avoid overly wet conditions, which can lead to rot. The soil should have a slightly acidic to neutral pH.
Fertilizing
Rabbit Foot Ferns do not require heavy fertilization. A balanced, diluted liquid fertilizer applied during the active growing season (spring and summer) is sufficient. Fertilize every two to four weeks at half or quarter strength to avoid burning roots. Discontinue fertilization during fall and winter when growth slows. Over-fertilization can lead to crispy fronds and salt buildup.
Understanding Repotting Needs
Rabbit Foot Ferns do not require frequent repotting, preferring to be somewhat root-bound. Repot only when clear indications show the fern has outgrown its pot, as frequent repotting can stress the plant.
Signs suggesting repotting include roots circling the pot or growing from drainage holes. A slowdown in growth or smaller foliage can also indicate crowded roots. If soil dries quickly after watering, roots may be taking up too much space. The best time to repot is typically in spring or early summer, allowing the plant to recover and establish itself during its active growth. Choose a new pot only one size larger with adequate drainage holes.
Repotting Your Rabbit Foot Fern
Repotting a Rabbit Foot Fern involves careful handling to minimize stress and correctly position its unique rhizomes. Gather your materials before beginning.
Prepare your new pot, which should be slightly larger and have good drainage holes. Add a layer of fresh, well-draining potting mix to the bottom. Gently remove the fern from its current pot by carefully tipping it or tapping the sides to loosen the root ball.
Inspect the root ball for any damaged or rotting roots, trimming them with clean pruning shears if necessary. Position the fern so the frond base sits just below the rim. Ensure furry rhizomes remain on top of the soil surface; burying them can lead to rot as they absorb moisture and nutrients from the air. Backfill around the plant with potting mix, gently firming to remove air pockets.
Post-Repotting Care and Common Issues
After repotting, proper care helps your Rabbit Foot Fern adjust and recover from transplant shock. Initial watering and placement are important.
Immediately water the fern thoroughly to settle the new soil. Place the plant in bright, indirect light, away from direct sun or drafts, to minimize stress during recovery. Temporary wilting or drooping for a few days is normal as it acclimates. Maintaining high humidity through misting or a pebble tray aids recovery.
Common issues can arise from improper care. Brown fronds often indicate insufficient humidity or underwatering. Yellowing leaves suggest overwatering, which can lead to root rot, or a nutrient deficiency. Stunted growth might be due to inadequate light, a need for nutrients, or the plant becoming root-bound.
