Troubleshooting
Lehmann's Ice Plant problems — and how to fix them
Lehmann's Ice Plant (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
Prolonged wet soil causes rapid root and stem rot. Ensure excellent drainage and allow full soil drying between waterings.
Spider mites
In dry indoor conditions, spider mites may colonise. Increase air circulation and treat with insecticidal soap if an infestation develops.
Leggy growth
Insufficient light leads to elongated, weak stems. Provide maximum available direct sunlight; trim back leggy growth in spring.
Pale or yellowing leaves
May indicate overwatering or, in bright conditions, a sign of nutrient deficiency. Adjust watering and apply a dilute feed in the growing season.
No flowers
Typically caused by insufficient sunlight or no winter rest period. A cooler, drier winter encourages spring flowering.
