Troubleshooting
Chinese Holly Fern problems — and how to fix them
Chinese Holly Fern (Cyrtomium devexiscapulae) 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.
Overwatering / root rot
The most common indoor failure. Yellowing fronds combined with a wet, heavy substrate signal root rot. Remove from the pot, trim rotted roots, let dry briefly, and repot into fresh, free-draining mix. Reduce watering frequency going forward.
Pale, washed-out fronds
Bleaching or yellowing of the glossy fronds suggests too much direct or bright indirect light. Move to a shadier position. Spider mites in dry conditions can also cause a similar stippled effect — check the frond undersides closely.
Spider mites in dry conditions
Fine webbing and tiny mites on frond undersides occur in hot, dry indoor air. Increase humidity, wipe fronds with a damp cloth, and treat with insecticidal soap spray. Rinse the plant thoroughly after treatment.
