The Christmas cactus is a popular holiday plant that can be easily propagated from cuttings. To take cuttings from a Christmas cactus, follow these steps: 1. Choose a healthy stem with 4-5 leaves on it. The cuttings should be about 3-4 inches long. 2. Use sharp, clean scissors or a knife to make a clean cut just below a node. A node is the little bump on the stem where leaves are attached. 3. Remove any lower leaves that may be present on the cutting.
