Seil, the whole thing is dried up, so there's no healthy wood for cuttings. Besides, I don't really like own-root roses. They usually don't measure up to their grafted counterparts.
Yes, David. They burrow through the garden and eat the roots (or sometimes the whole plant) of anything that isn't in a cage. After I caged my roses, they started killing all of the irises, abutilons, lavateras, silenes, and even a few camellias. In fact, they seem to like everything but the things I don't want in my garden -- blackberries, ivy, arum, privet, dandelions, etc.
