Southern Maidenhair Fern problems — and how to fix them
Southern Maidenhair Fern (Adiantum capillus-veneris) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frond browning and crispy tips
Almost always caused by low humidity or irregular watering; remove brown fronds at the base, increase ambient moisture, and water more consistently to allow fresh growth to emerge.
Scale insects
Soft brown or white scale can colonise the black stems; treat by wiping with a cotton pad dipped in isopropyl alcohol or use a systemic neem-oil drench, avoiding chemical insecticides that may damage the tender fronds.
