A Christmas cactus is a beautiful houseplant that requires special care during the holiday season. To start a Christmas cactus cutting, take a healthy stem from the plant and trim off any leaves or blooms. Then, gently place the stem into a pot filled with well-draining potting mix. Water the cutting regularly, but don't allow it to sit in standing water. Place the pot in a warm, sunny location, and keep an eye on it for any signs of root growth or new growth. Good luck!
