Troubleshooting
Rattlesnake Fern problems — and how to fix them
Rattlesnake Fern (Botrychium virginianum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Failure to establish after transplanting
The most common issue; this species is dependent on specific soil mycorrhizae and very rarely survives being dug up and moved. Source only from specialist nurseries that grow plants from spore, and minimise root disturbance when planting.
Single frond loss to physical damage
The plant produces only one sterile frond per season, which functions as the primary photosynthetic organ; physical damage (slug grazing, foot traffic, or hail) removes the plant's entire energy-gathering capacity for that year, leading to a weakened or absent plant the following spring.
