About Rabbit's foot fern
Davallia fejeensis · also called Rabbit's foot fern, Dainty rabbit's-foot fern · houseplant
The rabbit's foot fern is a delicate epiphytic fern from Fiji, prized for its lacy, finely divided fronds and the furry, rust-coloured rhizomes that creep over the pot rim like little paws. Its one defining need is steady humidity: dry indoor air quickly browns the frond tips, so consistent ambient moisture matters more than anything else.
Preferred mix: Light, free-draining epiphytic fern mix
Watch for — Rotting rhizomes: Caused by burying the fuzzy rhizomes or by leaving the pot in standing water. Always rest the rhizomes on the soil surface and tip away excess water from the saucer within 15 minutes.
Why rabbit's foot fern needs this mix
Rabbit's foot fern hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Rabbit's foot fern comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons rabbit's foot fern struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for rabbit's foot fern — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets rabbit's foot fern dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for rabbit's foot fern?
Rabbit's foot fern prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good peat-free houseplant compost works for rabbit's foot fern straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh rabbit's foot fern's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for rabbit's foot fern covers the timing and technique step by step.
