The cutting should be about 4-6 inches long and have at least 2-3 leaves. Cuttings can be taken from early spring to late summer. To promote successful rooting, the cutting should be placed in a potting mix that is light and well-draining. The pot should be kept moist but not wet, and in an area with bright, indirect light. Once the cutting has rooted, it can be transplanted into a larger pot or into the garden.
