how to root a christmas cactus in water

That's a good question! Christmas cacti are commonly propagated by cutting segments from the stems and placing them in a shallow dish of water. The segments should be large enough to have at least two to three leaf joints, and they should be cut at a 45-degree angle. Place the segments in the water, and change the water every few days to prevent it from becoming stagnant. The segments should start to root within a few weeks. Good luck!
