Rabbit Foot Fern 'Plumosa' (White rabbit's foot fern) care

Light

Bright but filtered. Rabbit Foot Fern 'Plumosa' burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright indirect light keeps the fronds full and the rhizomes active; tolerates medium light. Avoid direct sun, which scorches the delicate fronds, and very low light, which thins growth. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.

Watering

Watering rabbit foot fern 'plumosa': when the top 2-3 cm of mix is just dry, roughly every 5-7 days. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Keep evenly moist but never soggy; the furry rhizomes should sit on top of the mix, not be buried, and rot if kept waterlogged. Water the soil, not the rhizomes, and ease off slightly in winter.

Soil and pot

Rabbit Foot Fern 'Plumosa' grows best in light, airy, free-draining epiphytic mix. Use a loose, well-aerated medium such as a peat-free mix with bark, perlite, and coir, or an orchid-style blend. As an epiphyte it needs air around its roots; dense, water-holding soil causes rot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Rabbit Foot Fern 'Plumosa' sits happiest at around 50-70% humidity and 16-24°C (61-75°F). Loves higher humidity. In dry rooms the frond tips brown, so mist regularly, use a pebble tray, or group with other plants. The exposed rhizomes also appreciate humid air. If you keep the room above 16 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed rabbit foot fern 'plumosa' sparingly. A light feeder. Apply a dilute (half-strength) balanced liquid fertiliser every 4-6 weeks in spring and summer. Avoid strong feeds, which can scorch the fine roots. Stop feeding in winter when growth pauses. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on rabbit foot fern 'plumosa' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Rhizome rot from burying or overwatering — The furry rhizomes must rest on top of the mix; burying them or keeping the medium soggy causes them to rot. Surface-plant the rhizomes and use an airy, well-draining mix.
• Frond tip browning in dry air — Crispy brown tips are the classic sign of low humidity. Mist regularly, use a pebble tray, or move it to a more humid room such as a bathroom.
• Shrivelled rhizomes — If the creeping rhizomes look dry and shrunken, humidity and watering are too low. Raise humidity and keep the mix lightly moist so the rhizomes plump back up.
• Slow recovery after disturbance — It dislikes root disturbance and re-establishes slowly after repotting. Repot only when truly necessary and handle the rhizomes gently.

Propagation

Propagate by laying a section of the furry rhizome (with at least one frond) on the surface of moist mix and pinning it down until new roots and fronds form. Rhizome division in spring is the most reliable method. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Rabbit Foot Fern 'Plumosa' is pet-safe. The ASPCA lists Rabbit's Foot Fern (Davallia spp.) as non-toxic to cats and dogs. Humata tyermannii is sold within the same rabbit's-foot-fern group of the Davalliaceae and shares this non-toxic status, so it is considered pet-safe. As with any plant, discourage nibbling to avoid mild stomach upset. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
