Brilliantelse Maidenhair Fern problems — and how to fix them
Brilliantelse Maidenhair Fern (Adiantum raddianum 'Brilliantelse') 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.
Brown, crispy fronds
Almost always caused by low humidity or allowing the soil to dry out. Cut damaged fronds to the base, increase humidity, and resume consistent watering — healthy new fronds will emerge within weeks.
Frond collapse after repotting
Root disturbance causes temporary wilt. Keep humidity high, avoid direct sun, and maintain even soil moisture; the plant typically recovers within two to three weeks.
Scale insects
Small, waxy brown bumps appear on stems. Remove manually with a cotton swab dipped in rubbing alcohol and treat with neem oil spray, keeping the plant in good air circulation.
