What kind of dieback did the Ramblin' Red have; cane or crown? Just purchased a red for myself in zone 4 (NW Iowa) and wondering if it will benefit from protection over winter.
Just cane and not much die back , it is crown hardy , mine is own root though , after this winter I still have 3 to 4 feet of viable canes , will post a few pictures once in bloom , it is not in the same league as William booth or John Davis , those have no die back.
