Propogation

From Early Spring TO Early Spring

Moon cactus propagation is achieved by removing the offsets, which are smaller versions of the parent plant growing from the base of the rootstock. These divide away easily and root readily in a cactus potting soil.

Planting young plants

From Early Spring TO Early Spring

The moon cactus is usually sold already grafted in a process that removes the bottom of the Hibotan and the top of the rootstock cactus. The two halves are set together at the cut ends and soon heal together. The life of the moon cactus can be extended by re-grafting it onto a fresh rootstock.
