Christmas cacti are actually succulents, so they require similar care to other succulents. Here are some tips for propagating your Christmas cacti: 1. Cut off a healthy stem, making sure to include a few leaves. 2. Dip the cut end of the stem in rooting hormone, and then place it in a pot with well-draining soil. 3. Water the pot lightly and keep it in a bright, but not direct, sunlight. 4. Keep the soil moist but not soggy, and the stem should begin to root within a few weeks.
