Troubleshooting
Spreading Spike Moss problems — and how to fix them
Spreading Spike Moss (Selaginella kraussiana) 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 and desiccation
The most common problem — caused by low humidity or drying out. Restore moisture promptly and increase ambient humidity.
Legginess
Insufficient light leads to sparse, stretched growth. Move to a brighter indirect-light position.
Root rot
While it needs constant moisture, waterlogged soil causes rot. Ensure the growing medium is moist but well-aerated, not sodden.
Fungus gnats
Common in perpetually moist conditions. Allow the surface to just dry slightly between waterings and use yellow sticky traps.
Invasive spreading outdoors
In warm, moist climates this species can become weedy. In the garden, contain it to defined beds or use in enclosed pots.
