What kills ice plant?

Digging up, ground-covering patches, solarizing with weighted down black plastic sheeting, and using weed killers are ways to kill ice plant. The fig-marigold member of the Aizoaceae family can be eliminated by herbicides and by manual or mechanical removal. Its re-establishment is discouraged by solarizing with weighted-down black plastic sheeting until the vegetation is heated to death and then turning the area into a dense, lush ground cover.
