Troubleshooting
Leatherleaf Fern problems — and how to fix them
Leatherleaf Fern (Rumohra adiantiformis) 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.
Yellowing fronds
Often overwatering or compacted, soggy soil. Let the surface dry between waterings and use a free-draining, airy mix.
Browning frond edges
Low humidity or mineral build-up in the medium. Raise humidity and water with rain or filtered water; flush salts periodically.
Faded, scorched fronds
Too much direct sun. Move to bright to moderate indirect light to restore the glossy green.
Scale and mealybugs
Settle along rhizomes and frond undersides on this long-lived plant. Inspect routinely and treat with horticultural soap or oil.
