Succulents like Crassula ovata can be propagated by simply tearing a leaf from the stem and putting it into soil. The leaf will usually grow roots and additional leaves from the calloused wound, and eventually become a full Crassula plant itself.
Now I only have half of a leaf left, the other half got rotten, and dried out. In particular, the part of the leaf that was attached to the mother plant is missing. The remainder is about 3/4" long.
Is it still possible to grow a new plant from just this part of a leaf? Or is it at least necessary that the part of the leaf that was attached to the stem is still present?
