Why does your Davallia bullata (Hares Foot Fern) have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyDavallia bullata is highly susceptible to fungal pathogens like Pythium if the substrate remains saturated. Excessive moisture causes the rhizome to rot, preventing the fronds from receiving necessary water and nutrients, leading to yellowing.
As an epipetric fern, this species requires high ambient humidity. Dry air causes the delicate fronds to dehydrate rapidly, often manifesting as yellowing followed by crispy, brown edges.
If the potting medium is depleted of minerals, the plant cannot maintain chlorophyll production. Nitrogen deficiency typically causes a uniform yellowing of older fronds first.
While they enjoy bright, indirect light, direct afternoon sun can burn the thin tissue of Davallia bullata. This thermal stress disrupts photosynthesis and causes chlorosis or bleaching.
