What is eating my hay-scented fern?
Hay-Scented Fern is a robust and relatively pest-resistant fern indoors, but mealybugs and spider mites can appear in warm, dry rooms. If grown outdoors it is notably deer-resistant. Scale insects are possible on older fronds. Good airflow, appropriate humidity, and periodic inspection of frond undersides keep this fern largely trouble-free.
