SS gardener,
Yes, you may cut the stem but depending what type it is will tell what sprouts up. At the beginning of this thread, my picture is stem cuttings of Sans. Trifasciata Laurentii. What sprouted up was the all green Trifasciata. No yellow edges. But still looks good to me. If you cut it, do it in spring when the weather is warmer. Start your cutting in pure pumice. Small pot with about 3 inches and keep on the dry side untill you see some growth. Maybe a slight watering after a few weeks. Do not let it sit in water.
