Maidenhair fern problems — and how to fix them
Maidenhair fern (Adiantum raddianum) 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 fronds
A single dry-out event — soak, trim back, and improve humidity.
Pale washed-out fronds
Too much direct light or hard tap water.
Yellow fronds
Overwatering or stagnant soil.
Whole plant collapse
Dry air combined with cold drafts; move and revive with a humidity dome.
