Troubleshooting
Ashton's Ice Plant problems — and how to fix them
Ashton's Ice Plant (Delosperma ashtonii) 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.
Winter rot
Waterlogged soil in cold, wet winters is the primary cause of plant loss. Ensure excellent drainage or plant in raised beds.
Reduced flowering
Insufficient light or over-fertile soil limits blooming. Full sun and lean soil are key.
Aphids on new growth
Treat with insecticidal soap or a strong water jet. Monitor in spring when growth resumes.
Centre dieback
Older mats can die out in the centre. Rejuvenate by dividing and replanting vigorous outer growth.
Slug damage
Slugs can notch and damage fleshy stems. Use iron phosphate pellets or physical barriers in damp conditions.
