Troubleshooting
Spike Moss problems — and how to fix them
Spike Moss (Selaginella apoda) 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.
Desiccation and browning
The most common problem — even brief drying causes rapid browning. Maintain consistent moisture at all times.
Fungal rot
In overly wet, stagnant conditions rot can set in. Ensure air circulation and avoid standing water around the root zone.
Pale or yellowing growth
Usually caused by excessive light or low nutrients. Move to a shadier spot and apply a dilute feed.
Fungus gnats
Common in consistently moist soil. Allow a thin surface layer to dry slightly between waterings and use yellow sticky traps.
