Troubleshooting
Male Fern problems — and how to fix them
Male Fern (Dryopteris filix-mas) 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
Drying out or low humidity, especially indoors. Keep evenly moist while establishing and raise humidity in heated rooms.
Scorched foliage
Too much direct sun. Move to partial or full shade, where it performs best.
Tatty fronds after winter
Old semi-evergreen fronds get weather-damaged. Cut back to the crown in late winter before new fiddleheads unfurl.
Slow or sparse growth
Very dry, impoverished soil or a cramped pot. Improve organic matter, water more attentively while establishing, and divide congested clumps.
