Any fully grown pad from this cactus may be broken off cleanly in the early summer and repotted for propagation purposes. Cuttings work best when grouped in threes or more, and should be buried an inch (2.5 cm) deep in the soil. Remember to water regularly to promote the growth of a healthy root system in the first year after propagation.
