Troubleshooting
Silvery Glade Fern problems — and how to fix them
Silvery Glade Fern (Athyrium thelypterioides) 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 die-back in winter
This is a deciduous fern and will naturally die back to the ground in autumn and winter, especially in cooler indoor or outdoor positions. This is not a problem — simply trim dead fronds and expect fresh growth to emerge in spring.
Frond edge browning
Caused by low humidity, inconsistent watering, or draughts. Ensure ambient humidity stays above 50%, maintain even soil moisture, and keep the plant away from cold window draughts and heating vents.
Slug and snail damage
When grown outdoors or in conservatories with open access, slugs and snails target the tender emerging fronds in spring. Apply organic slug control (copper tape, wool pellets, or nematodes) as new fronds unfurl to protect the season's foliage.
