Last year I 'tried' to root an Oak Leaf hydrangea cutting. It just didn't happen, even with rooting hormone. I now have another cutting. Since the 'stem' is rather woody on the Oak Leaf, can you tell me the best/easiest way to root these?

I would try again with traditional rooting methods. Even the best professional gardeners do not have a 100% success rate. Keeping humidity up around the cutting it key to success though.
Honey is not a rooting hormone like willow water, but it can help in rooting cuttings. It is anti-bacterial and helps to keep disease away from the open wound on the cutting, which means that the cutting will have a better chance at rooting.
