You can try rooting stem cuttings from many woody plants. Springtime is the best time to perform this procedure because of the new green tender growth, that will root more readily.Prepare a container or several with sterile soilless growing medium. It should be all ready moist before you take your cuttings. If it will be awhile before you get them into moist soil, (for instance, a friend has offered some cuttings), wrap them in a moist towel and put in a plastic bag. They shouldn’t be exposed to air more than a few minutes for best success.
Take some cuttings with a sharp knife just below a node or 3 to 5 inches from the tip of the stem. Take several because you might not get all to take root.
Strip all leaves from the lower half of the stem. Remove any flowers or buds.
Dip the base of cuttings in rooting hormone, available from a nursery. Put the rooting hormone you will be using in another container so you don’t contaminate the whole bottle.
Plant about 1 inch deep.
Water and cover with a plastic bag. The bag shouldn’t touch the cuttings so fashion a tent support with a coat hanger or sticks that you place in the soil. Seal up the bag.
Keep in a cool place with indirect bright light.
You want your little greenhouse to have high humidity so if necessary mist the plant.
Check for root growth after two weeks; it is hard to say how long it will take, all plants are different. Once you have root growth, remove the tent and treat as you would a new plant from the nursery.
