Troubleshooting
Maidenhair Spleenwort problems — and how to fix them
Maidenhair Spleenwort (Asplenium trichomanes) 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.
Root rot from sogginess
This crevice fern hates wet feet. Use a very gritty, sharply drained mix and avoid leaving the pot standing in water.
Drying out and shrivelling
Small rootballs dry fast. Keep lightly moist and shaded from direct sun, especially in warm rooms.
Chlorosis on acidic mix
Pale fronds can appear if the substrate is too acidic. Add limestone grit or chippings to nudge toward its preferred neutral-to-alkaline range.
Weak, sparse growth
Too little light or excess nitrogen. Move somewhere brighter (indirect) and feed only lightly.
