Troubleshooting
Lehmann's Iceplant problems — and how to fix them
Lehmann's Iceplant (Delosperma lehmannii) 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.
Root rot from overwatering
Mushy stems at the base signal root rot, typically from overwatering or poor drainage. Allow soil to dry fully between waterings and use a pot with ample drainage holes.
Frost damage
Not cold-hardy below about -3°C (25°F). In temperate climates, move containers indoors before the first autumn frost and keep in a cool but frost-free spot through winter.
Failure to flower
Most often caused by insufficient direct sunlight. Ensure the plant receives at least 4–6 hours of direct sun. Plants that have not been given a cool winter rest period may also bloom less freely.
