Squirrel's Foot Fern Care & Identification Guide

The magnificent Squirrel's Foot Fern (Davallia mariesii) is a highly spectacular and robust semi-evergreen species, native to rocky cliffs, mossy stone slopes, and ancient tree trunks in East Asia. Celebrating its thick, reddish-brown shaggy creeping rhizomes that resemble the furry tail of a squirrel, it is highly prized in Japanese traditional horticulture for micro-bonsai and moss ball displays (Kokedama). Extremely cold-hardy, it can survive winter dormancy, requiring bright indirect light, porous gritty peaty soil, and moderate watering.

11-Step Professional Care Guide

💧 【Watering & Moisture】 Water moderately. Allow the gritty potting medium to dry out slightly between waterings. Highly tolerant of brief dry periods due to its thick rootstocks.

☀️ 【Sunlight & Exposure】 Requires bright, filtered indirect light or partial morning sun. Avoid direct afternoon sun which will bleach the glossy green color.

🪴 【Ideal Soil Mix】 Prefers a highly drained, porous peaty-sandy mix. Blend 40% peat, 30% coarse perlite or pumice, and 30% fine gravel or sand.

🌡️ 【Temperature & Ventilation】 Cold-hardy (USDA Zone 7). Excellent at surviving winter dormancy. Protect from freezing winter drafts.

✂️ 【Pruning & Grooming】 Cut away old, winter-damaged fronds in early spring to keep the symmetrical dome neat and encourage colorful new growth.

🧪 【Fertilization】 Feed very lightly once in early spring with a slow-release organic fertilizer. Avoid strong chemical feeds.

🏺 【Potting & Container】 Terracotta pots with drainage are excellent. Highly suited for Japanese moss balls (Kokedama) or shallow bonsai pots.

🌱 【Propagation】 Propagated by slicing a section of the shaggy creeping rhizome in spring. Ensure each division has at least one active crown.

🐛 【Common Pests】 Generally highly resistant to pests. Watch for occasional scale insects along the leaf stems. Wipe off manually.

🦠 【Common Diseases】 Highly susceptible to root rot if soil is compacted and soggy. Porous soil is essential.

🎓 【Botanist Advice】 The Squirrel's Foot Fern is a true classic in traditional Japanese horticulture. Bind its roots with moss onto a rock or inside a Kokedama moss ball—it looks absolutely magnificent!
