Troubleshooting
Ursula's Red Painted Fern problems — and how to fix them
Ursula's Red Painted Fern (Athyrium niponicum 'Ursula's Red') 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.
Frond tip browning
Almost always caused by low humidity or dry soil. Increase ambient humidity with a pebble tray or humidifier, and ensure the compost never dries out completely between waterings.
Loss of red coloration
Insufficient light causes fronds to revert toward green. Move the plant closer to a bright, indirect light source. Avoid deep shade; the red and silver pigments need moderate light intensity to express fully.
Crown rot
Caused by waterlogged compost or water pooling at the base of the crown. Ensure excellent pot drainage, never let the plant sit in standing water, and repot into fresh well-draining mix if rot is detected.
