Succulents terrariums are very popular as they offer many planting options. The variegated or crested varieties can be propagated using cuttings. However, the roots of the crested and variegated succulents are more difficult to grow and are often grafted. You can remove the dead roots and rotten leaves, then place the succulent in a shade area. Let it dry thoroughly. It is sometimes impossible to plant succulents in a suitable container because of all the cute potential planters.
