Crispum Hart's Tongue Fern problems — and how to fix them
Crispum Hart's Tongue Fern (Asplenium scolopendrium 'Crispum') 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.
Browning frond margins
Caused by dry air or letting soil dry out. Keep soil evenly moist and raise humidity, particularly indoors in winter.
Scorched, bleached fronds
Direct sun damages the glossy surface. Move to shade or bright indirect light to keep fronds deep green.
Crown or root rot
From waterlogged, poorly drained soil. Add grit and ensure free drainage; never leave the crown sitting in water.
Tatty old fronds
Older fronds naturally brown over time. Trim spent fronds at the base in spring to let fresh ruffled growth emerge.
