transplanting mature roses
I have what I believe to be a grandiflora that has been in the same place for probably 20 or 30 yrs. As far as I know it has never been touched. I've trimmed off all of the dead parts to it, now it's about half the size it was. It's about 8-10 ft tall, about 10-12 ft across, there are four 'stalks' at the base about 1-1.5" across. One of these comes out horizontally. My question is this: What is the best way to move a plant this large? I figure I'll have to do it bare root, then come back for some of it's dirt to try to reduce some of the shock. Should I remove the part that comes up horizontally? I'm going to assume that it will need support (It's leaning on several downed trees), what is the best way to do this? Any insight I can get is greatly appreciated!! Thank you!!
