You can pluck a leaf from your plant Alex, then let it callus. You can also dab a little cinnamon on the cut end, natural fungicide. Stick your cutting in a well draining media, put the container in shade or part sun area. It likes our mild winters a lot, so it is more active growing here during our cold months, and blooms in Spring to early summer. You may want to wait a little bit during Spring to do your leaf cuttings.
