Cyrtomium macrophyllum problems — and how to fix them
Cyrtomium macrophyllum (Cyrtomium macrophyllum) 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.
Scale and mealybugs
Like other holly ferns, prone to scale on the broad frond undersides. Remove by hand and treat with horticultural soap or oil.
Sunburnt, bleached pinnae
The large leaflets scorch readily in direct sun. Move to a shadier, filtered-light position.
Browning frond margins
Indicates dry roots or very dry air indoors. Keep soil evenly moist and raise humidity around the plant.
Yellowing lower fronds
Often overwatering or poor drainage. Let the surface dry between waterings and ensure the pot drains freely.
