Troubleshooting
Lady Fern problems — and how to fix them
Lady Fern (Athyrium filix-femina) 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.
Crispy brown frond edges
Almost always low humidity or the soil drying out. Raise humidity and keep the rootball evenly moist; trim spent fronds at the base.
Yellowing, collapsing fronds
Usually overwatering in poorly drained soil leading to root suffocation. Improve drainage and let the surface barely dry between waterings.
Scorched, bleached patches
Direct sun on the thin fronds. Move to filtered light or dappled shade.
Winter dieback mistaken for death
It is deciduous and naturally collapses in autumn. Keep the crown barely moist and cool; fresh fiddleheads return in spring.
