Troubleshooting
Common Iceplant problems — and how to fix them
Common Iceplant (Mesembryanthemum crystallinum) 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 in poorly drained soil
Even brief waterlogging quickly causes basal rot in this succulent annual. Always grow in free-draining media and avoid overhead watering in cool, overcast conditions.
Aphids on young growth
Soft new shoots attract aphids, especially in sheltered indoor environments. Blast off with water, introduce beneficial insects outdoors, or use insecticidal soap for persistent colonies.
Failure to establish after transplanting
Direct sowing is generally more successful than transplanting, as young plants resent root disturbance. If transplanting, handle roots gently, do not over-firm the soil, and water in carefully.
Prevent common iceplant problems before they start
Most common iceplant issues are care-mismatch, not bad luck. Dial in the basics:
