Troubleshooting
Mother Fern problems — and how to fix them
Mother Fern (Asplenium bulbiferum) 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.
Crispy, browning fronds
Low humidity or the soil drying out. Keep humidity high and the mix evenly moist; trim damaged fronds at the base.
Frond collapse
Usually a sign the rootball dried out completely. Rehydrate by soaking the pot, then maintain steady light moisture going forward.
Rhizome rot
From soggy, poorly drained soil. Improve drainage with perlite and bark, and let the surface dry slightly between waterings.
Plantlets failing to root
Bulbils need contact with moist soil and humidity to take. Pin frond tips onto a tray of damp mix to encourage rooting.
