Rooting Noisette cuttings
I have a fair degree of success rooting roses, mostly old and shrub varieties, but do poorly with Noisettes as a class. I would have thought they wouldn't be that difficult. Usually I root semi-hardwood cuttings over the winter in a cold greenhouse and plant them out after a year; or I root softwood cuttings in pots over the summer or fall. I don't use rooting hormones, and while my methods are crude, they work a good deal of the time. Not for Noisettes, however. Any hints? Thanks.
