Is it best to propagate cacti by using cuttings?
This method does provide larger plants more quickly than propagation by seed, but not every type of cactus can be propagated this way. Cacti that are columnar or pad-forming, and those that have segmented stems such as a Christmas cactus, are easily started from cuttings. Spring, when most cacti emerge from their winter rest and initiate new growth, is the best time to take cuttings. The most important point in ensuring success is that the plant you take the cuttings from is very healthy. The primary problem encountered with cactus cuttings is fungal soft rot.
