Troubleshooting
African Chain Fern problems — and how to fix them
African Chain Fern (Woodwardia radicans) 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 and margins
Typically caused by low humidity or erratic watering. Increase humidity and maintain consistent soil moisture.
Scale insects
Brown, waxy bumps on frond undersides and stems. Scrape off manually and apply neem oil or insecticidal soap.
Frond yellowing
Overwatering or poorly draining soil is the usual cause. Ensure the pot drains freely and reduce watering in cooler months.
Slow growth indoors
This fern is naturally a large plant; in containers its growth is restricted. Repot every 2-3 years into a larger container with fresh compost.
Frost damage outdoors
In borderline hardy zones, protect the crown with a deep mulch in winter or move containers under cover.
