Troubleshooting
Nevada Lewisia problems — and how to fix them
Nevada Lewisia (Lewisia nevadensis) 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.
Taproot rot during summer dormancy
This is the single most common cause of failure: continued watering or summer rainfall reaches the dormant taproot and causes fatal rot. Ensure the plant is kept bone-dry once foliage dies back, ideally under glass or a raised canopy.
Failure to re-emerge in autumn
If the taproot desiccates completely during a prolonged dry summer, the plant may not resume growth. Apply a very light misting in late summer to signal the return of autumn moisture, mimicking natural mountain conditions.
