How to prune coryphantha vivipara

Spring or early summer for offset removal. Gently twist or cut offsets away from the mother plant at their narrowest point using sterilised scissors or a knife. Let cut ends callous for several days in a dry, shaded spot before potting into dry cactus mix.

You can detach offsets (pups) from the base in spring if the clump is overcrowded or you want to propagate. Otherwise, no pruning is needed — the clustered form is natural and healthy.
