The Q&A Archives: Ice Plants

Question: What should I do with my ice plants this fall to keep them from freezing?

Answer: Ice plants (Mesembryanthemum) are certainly unique, but they are annuals, and they will die when cold temperatures hit. Fortunately, they are very easy to grow from seed sown outdoors in the spring or indoors about 8 weeks before the last frost date. If you start them indoors, keep them at temperatures of about 60-65 degrees F. As you probably already know, ice plants prefer coarse soil that drains well. If their feet stay soggy, the leaves will not exhibit the glistening, icy appearance.
