Troubleshooting
Spartan Cliff Stonecrop problems — and how to fix them
Spartan Cliff Stonecrop (Prometheum laconicum) 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
This is a cliff endemic unaccustomed to sitting in moisture. In winter, keep nearly dry in a cool, well-ventilated spot. Use gritty soil and pots with drainage holes.
Mealybugs
Compact rosettes trap debris and provide shelter for mealybugs. Inspect monthly and treat with isopropyl alcohol swabs; follow with a diluted neem oil spray.
Etiolation in low light
Without sufficient light the tight rosette opens up and becomes lax. Move closer to a bright window or supplement with a full-spectrum grow light in short winter days.
