When I went to trim the dead out of another shrub rose I have, 'Chuckles,' I found that I had to cut back to 4" from the ground to get to live wood. Never had that rose die back that far.
Since the rose I posted about, DayDream, still has not leafed out, maybe the winter killed it back too. I am not seeing and leaf buds or anything out on the canes. I hope it is still alive.
With no replies on my post, I guess I will just have to get in there and start cutting and go with my instinct.
I have had this rose for so many years. I hope I don't do the wrong thing.
