Troubleshooting
Oak Leaf Fern problems — and how to fix them
Oak Leaf Fern (Drynaria quercifolia) 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.
Browning foliage frond edges
Low humidity or under-watering. Raise humidity and keep the basket from drying out fully.
Mistaking dead nest fronds for disease
The persistent brown oak-leaf nest fronds are naturally papery and brown; they are functional, not dying, so leave them in place.
Rotting rhizome or base
Overwatering or dense, soggy substrate. Use a coarse, airy mix and let it dry between waterings.
Slow or stunted growth
Too cold or too dark. Provide warmth above 18°C and bright, indirect light.
