Tassel Fern pests — FAQ
What is eating my tassel fern?
Tassel Fern (Polystichum polyblepharum) is a glossy-fronded houseplant that can fall prey to scale insects — the glossy surface allows pests to hide in plain sight along midribs. Spider mites appear in low humidity, and mealybugs may cluster at the crown. Fungus gnats occur if watering is excessive. Inspect the plant crown and frond undersides every few weeks.
