I just take cuttings about a foot long, from the tip, stick them in rich potting soil/sand mix (half and half), water them in, and keep adding water to the saucer under the pot, which is teracotta. I have about 75% success. I always use a new razor blade when I take cuttings to avoid diseases.

Thank you so much for your good advice. Shall do it your way, since mine did not succeed,
