Propagation by Cuttings
Hardwood cutting is the best method for propagation. Cuttings should be taken from the stem’s basal region during late winter or early spring. Dip the cuttings in rooting hormone powder and place them in a rooting medium composed of peat moss and coarse sand. Keep the cuttings in a greenhouse or protected area out of direct sunlight to encourage root growth. Cuttings should root in 2 to 3 months, at which point they can be transplanted.
