Pruning down to the bud union is an extreme measure to renew a dying rose but if it worked for you Lyn so be it.For ZUZU-where did you get a rose grafted on Fortuniana RS 10-12 years ago if I may ask??? I understand about the size of your Fort grafted rose I have about 75 hybrid teas on Fort RS and I just fall pruned them by cutting off an average of 4 feet on each one.I am getting ready for a Rose show in Tallahassee if the hurricanes will just leave me alone.!!
