Propagation

From Early Spring TO Late Winter

The most common form of propagation for succulents is called vegetative propagation. This involves cuttings, where several inches of stem with leaves are cut, allowed some time to heal and after healing produce a callus. After a week or so, roots should grow. Another method is division which involves uprooting an overgrown clump and pulling the stems and roots apart. The easiest method is to allow the formation of a callus from a leaf or segment.

Planting

From Early Spring TO Early Spring

Succulents need good draining soil. When planting in the garden, make sure the area drains well and is not in a hollow that remains wet. Specially prepared cactus soil can be purchased for planting in pots or incorporate sand, gravel or volcanic rock for better drainage. The container you are planting in should have a drainage hole and it is wise to put crushed rock at the bottom before your planting medium.
