I had great luck rooting these. I potted them up and watered the cuttings, then placed them in a large ziplock bag that I had misted the inside with water. I then blew air into it as I closed it. I have a greenhouse, so I put them in a shady area inside the greenhouse. If I was doing it without the greenhouse, I would do the same, but then place it in a shady area . Everyone
of mine rooted.

Cold you give more details? I took long cuttings, about 18" and stuck in some 5 gallon pots, I keep moist in the shade. I need to take more cuttings and want to be successful.
