Anyone try air layering for hard to root ones?
I have some roses that are consistently hard to root. Most have lots of smallish thorns, like Gertrude Jekyll and Common Moss. I'm considering air layering, and think semi-hard wood done at this time of year might work. The way I understand it, you make an angled cut part way through a cane above a node. Put some damp peat moss in and around the cut and enclose in plastic. Maybe it would be good to cover that with something opaque so it won't trap too much heat. Am thinking that if I left that in place long enough there might be roots in spring. I know the kind of layering works where you take a trailing branch and pin it to the ground, but my Gertrude plant doesn't trail. It goes up and out. I guess I'll just try it and see if it works.
