How to Propagate Euphorbia cereiformis “Milk Barrel Cactus”

Euphorbia cereiformis “Milk Barrel Cactus” is a quick grower, and will produce offsets that sprout up around the base of the plant. Use care when removing these offsets. Follow the directions in this post to learn how to handle a cactus safely.

To remove a clump for propagation, you will need nitrile dipped glovessilicone tongs, and a sharp knife.

Using the tongs, gently pull one of the cylindrical stems away from the main cluster. If you are not able to break it off without pulling up the rest of the plant, use the knife to cut through the stem.

Allow the end of the stem to callous over for several days before placing in well-draining soil.
