I've not done this with woody plants before, but I would take some new growth,
maybe with a bud on the end (2-3" long). Skin a little bark off the botton
1/4" or so and dip in rooting hormone, then put in moist potting soil. Out
here in AZ I keep my cuttings moist by inverting a clear plastic cup over them
(careful with sun though). Hope this is of some use.
