This should be done for every succulent, so that you only have the cuttings. Cuttings are at greatest risk as they lack roots. So plant them after the winds have gone. Succulent plants can be related but not necessarily related. Any plant that is able to store water in its roots or leaves, stem, or roots, is a succulent. Apply a pre-emergent herbicide that is environmentally friendly to the ground surrounding the plants before winter rains to stop weed seeds from germinating. 3) Use a weed control (pre-emergent insecticide) Use sharp, clean scissors to cut your cuttings.
