Blue Rabbit's Foot Fern problems — and how to fix them
Blue Rabbit's Foot Fern (Davallia solida) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Shrivelling rhizomes
Indicates the plant has been allowed to dry out completely. Soak the entire pot or basket in water for 30 minutes to fully rehydrate the rhizomes.
Frond tip browning
Caused by low humidity or fluoride in tap water. Raise humidity and use rainwater or filtered water.
Root rot
Caused by overwatering or dense, poorly draining media. Trim any rotted rhizome sections and repot into a coarser, more open mix.
Scale insects
Small brown scales on rhizomes and fronds. Remove with a cotton bud dipped in isopropyl alcohol and apply neem oil.
Frond drop in autumn
Normal seasonal behaviour in lower light. Maintain warmth and reduce watering until new fronds emerge in spring.
