Troubleshooting
Macho Fern problems — and how to fix them
Macho Fern (Nephrolepis biserrata 'Macho') 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.
Rapid drying and wilting
Its size and vigour make it thirsty, especially in containers and heat. Water more often and consider a larger pot or a self-watering setup; mulch outdoor plants.
Browning frond tips and edges
Low humidity or under-watering. Raise humidity and keep the rootball moist; trim tatty fronds at the base to keep the plant tidy.
Cold or frost damage
Fronds blacken below about 5°C. Bring containers indoors before frost; in borderline zones treat it as a tender summer plant or annual.
Crowded, pot-bound clumps
Vigorous roots quickly fill a pot, causing fast drying and stalled growth. Repot or divide every year or two in spring into fresh, fertile mix.
