Ok I'm confused. I have 7 beautiful Grandiflora bushes and one Don Juan Climber. They are located against a south wall coming up to my front door. Should they be covered every winter???? And if so, when do I cut them back in order to cover them. I live in southeast Michigan. Thank you for your help. I've been told to cover and not to cover. They are 4 years old. I have been covering them.
Thanks!!
