My cactus has outgrown its space. It is prolific! This year it bloomed at Christmas. All the blosspms fell and it bloomed again for Valentines Day!
But it is causing space problems and I don't have another location to put it. How do I prune or divide it without killing it?

Christmas cactus aka zygo cactus actually likes to be a little pot bound. transplant to a bigger pot when it is at least 2-3 years old. Don't put it in a big pot. Splitting the plant for propagation is better done in late spring or early summer, although Christmas cactus isn't usually divided at the roots, instead stems are removed (at least 4 sections) and potted up to grow into new plant similar to rooting a pad of prickly pear cactus.
