Troubleshooting
Fringed Cliff Stonecrop problems — and how to fix them
Fringed Cliff Stonecrop (Prometheum fimbriatum) 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 waterlogged soil
Persistent moisture at the rosette crown causes rapid fungal rot. Always water the soil rather than the plant, ensure drainage is excellent, and avoid overhead irrigation.
Slug and snail damage
Young rosette growth is vulnerable to slug and snail damage, particularly in spring. Use copper tape around containers, or apply organic iron-phosphate pellets around the planting area.
Etiolation in low light
The distinctive compact, fringed rosette form deteriorates in shade, producing loose, stretched growth. Full sun is essential for this species to display its characteristic form.
