Rabbit’s Foot Fern

The rabbit’s foot fern (Davallia fejeensis) has more intricate foliage than a Boston fern, and its rhizomes are fascinating (although scary for some—there’s a reason it’s mistakenly called “tarantula fern”). The fronds of this fern don’t dry up in a mess of leaves; instead, they gradually turn yellow and fall off as one piece.

Survival strategy

This fern seems to be able to maintain itself with low light hovering around 100 foot-candles. The plant won’t grow much and will likely thin out, losing a number of fronds, but it should remain lush enough to keep you interested. While it can tolerate completely dry soil, you’ll need to gently loosen it with a chopstick before watering, or else the compacted pockets will never get wet. Just be careful not to pierce the rhizomes.

Growth strategy

With 200 or more foot-candles, the frond turnover should be slower. You can comfortably bring the soil to saturation whenever it becomes partially dry. The soil should be aerated occasionally. A general-purpose fertilizer will do whenever you find the plant is in growing mode, when several new fronds are unfurling.

Subjective life span

If you provide it with enough light, the rhizomes of this fern may completely surround its container in a few years. At this point, you can divide the entire plant or simply cut off a few rhizomes and transplant them into new soil.

As they mature, they will eventually become a lighter green, like the rest of the mature fronds.

Rhizomes

In ferns, the rhizome is simply a horizontal root stem that grows out from the mother plant above the soil and is capable of sending out new roots and new fronds, generating a new plant. The more established rhizomes of the rabbit’s foot fern have light-brown “fur,” while the new growing tips are white with a slight green tint.

Note the emergence of new fronds from the hairy rhizomes: They are initially a dark brownish green—don’t mistake them as being sick!

Repotting a Rabbit’s Foot Fern

I put this rabbit foot’s fern into a cachepot for now until I can decide on a planter that will accentuate its most interesting feature—the furry rhizomes!

A year later, I found an interesting glass container for my rabbit’s foot fern. After removing some of the old soil, I’ll use sphagnum moss to line the inside of the container, as it doesn’t have drainage holes.

Any time you transplant, it’s a good idea to loosen some of the old soil from the root ball so that the roots can more easily explore the new soil.

Eight months since repotting: Living in my bathroom, this plant receives a daily high of around 200 foot-candles. At this light level, I notice the sphagnum moss becomes completely dry in approximately a week’s time. Because the container lacks drainage holes, I slowly pour in a volume of water equivalent to a quarter or a third of the total volume of sphagnum moss. This will adequately moisten the entire volume of moss.
