Take hardwood cuttings from mature wood, 10-12 inches long, and set the cuttings 3/4 of the way into the ground. New roots will strike from a number of areas along the stem. In colder areas, cover these cuttings with mounds of dirt or straw to prevent heaving. The following year these rooted cuttings may be set into the garden. Another method of propagating is by layering. Bend a low-growing branch to the ground and cover with soil. Keep the branch under the soil by weighing it down with a rock, or fashion a pin from a coat hanger and pin it down. Layering can be done in fall or spring. Once the roots are established, cut the branch off and plant in its permanent place.
