Christmas cactus cuttings can be propagated easily with the following steps:
1. Select a healthy, mature branch of the Christmas cactus that is at least 4 inches long.
2. Use a clean, sharp knife to cut off the branch. Make sure to cut at a 45-degree angle so that the cut is clean and smooth.
3. Remove any leaves from the bottom third of the branch.
4. Place the cuttings in a pot filled with well-draining potting soil.
