You might want to read this thread.
The thread "Finally got 'em planted!" in
Roses forum
@Cotton is gardening in a much hotter and arid climate than yours, but he, too, is planting "body bag" roses. The info posted there can help you understand about the need to grow roots.
My rule of thumb when I am planting canned roses is not to disturb the roots at all. Any time you plant a rose or transplant a rose, you are going to break off some of the feeder roots. It can't be helped.
Just do the best you can. Roses are tough.
