What is eating my venus maidenhair fern?
Venus Maidenhair Fern is particularly vulnerable to spider mites, which exploit the low humidity that also stresses the plant. Scale and mealybugs can colonize the delicate black stems. Fungus gnats breed readily if the fine-textured potting mix is kept too wet. Consistent humidity above 50% is the single best pest deterrent for this species.
