Dig up underground rose shoots?
I bought a home in NY state that has a garden of mostly perennials. The previous owners planted a rose bush and it has spread underground throughout the perennials and there are long canes lying atop everything, with roses at just the ends. How do I manage these? Do I just cut everything back to the ground? Do I dig some of the spreading parts up and replant them? I have found the original plant and think the rest spread from there. I don't even know what kind of rose it is - if a climber or what! I don't want it to take over the perennials and if I could relocate the roses that would be good.
