Troubleshooting
Prickly Ice Plant problems — and how to fix them
Prickly Ice Plant (Delosperma echinatum) 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 and stem rot
Overwatering is the chief threat. Ensure the pot has drainage holes and the soil dries fully between waterings.
Mealybugs
White cottony clusters can appear in leaf axils. Dab with a cotton swab dipped in 70% isopropyl alcohol or apply an appropriate systemic insecticide.
Etiolation
Spindly, pale growth in winter indicates insufficient light. Use a grow light or move to the brightest available position.
Leaf shrivelling
Paradoxically, this can indicate both underwatering and overwatering (root rot reducing uptake). Check the roots and reassess watering schedule.
Failure to flower
Insufficient direct sunlight is the most common cause. Move to a brighter position and ensure a cool winter rest period to encourage spring bud set.
