Pacific Maid Maidenhair Fern problems — and how to fix them
Pacific Maid Maidenhair Fern (Adiantum raddianum 'Pacific Maid') 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 browning fronds from low humidity or drought
Fronds brown and shrivel with alarming speed if humidity drops or soil dries out. Cut all brown fronds back to the base — the plant will reshoot if roots are healthy. Increase humidity immediately and keep soil moist.
Yellow, dropping fronds from overwatering or cold
Yellow fronds signal overwatering, cold draughts, or waterlogged roots. Ensure the pot drains freely and temperatures stay above 15°C. Remove yellow fronds at the base and adjust watering.
Scale insects and mealybugs
The fine stems and dense frond canopy provide cover for scale insects and mealybugs. Inspect regularly; treat with neem oil or insecticidal soap, taking care to coat both sides of fronds and the stems.
