Troubleshooting
Stonecrop Rosularia problems — and how to fix them
Stonecrop Rosularia (Rosularia sedoides) 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.
Crown rot in wet winters
The most significant threat. Water pooling in the rosette centre in cold, damp conditions rapidly kills the plant. Grow in raised beds, troughs with overhang protection, or bring pots under cover in wet winters.
Aphids
Soft-bodied aphids cluster on new growth and flower stems in spring. Remove by hand or apply insecticidal soap or neem oil. Avoid broad-spectrum insecticides that harm beneficial insects.
Etiolation in low light
Rosettes stretch and open up when light is insufficient. Relocate to a brighter position; the stretched form cannot revert but new growth will be more compact.
