I'm glad you asked! Taking a cutting from a Christmas cactus is actually a pretty simple process. First, you'll need to find a healthy part of the plant that has no signs of disease or damage. Next, using a clean, sharp knife or pruning shears, cut off a stem about 4-6 inches long. Make sure to cut it at an angle to allow for proper water absorption. Finally, place the cut end in a jar of water and keep it in a well-lit, but not direct sunlight area. The cutting should begin to root in a few weeks!
