Take a current season's shoot, cutting above a leaf joint. It should be about 3' long. Divide the shoot into cuttings with a knife. The top of each cutting should be immediately above a leaf joint, the bottom a couple of inches below the joint. Dip it in rooting powder.Put several cutting around a small pot filled with a half-and-half mix of compost and grit. The leaf joint (only leave one leaf on) should be level with the surface. Cover with a clear plastic bag after watering. They should root in a few weeks. However, I find that I lose cuttings all the time,too. Layering is said to work. The only cuttings I've had success with are semi-ripe ones with a heel from more woody clematis. If the 'official' method works, please send me your tips!!.
