Troubleshooting
Holly Fern problems — and how to fix them
Holly Fern (Cyrtomium falcatum) 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.
Brown frond tips
Low humidity, underwatering or salt build-up. Keep soil evenly moist, flush the pot occasionally, and raise humidity slightly if very dry.
Scale insects
This fern is prone to scale; brown bumps on stems and frond undersides. Wipe off and treat with horticultural oil, avoiding harsh insecticides on ferns.
Yellowing fronds
Usually overwatering or poor drainage. Let the surface dry between waterings and ensure the pot drains freely.
Faded or scorched leaflets
Too much direct sun. Move to bright indirect light to keep the glossy green colour.
