Once they're established (I'd say 3rd year qualifies as established) you may notice a slight setback after relocating them, but you have to remember they have all of last year's reserves saved up and ready to go. I would suspect you'll get at least the same vigor as last year if not more. Usually by the 3rd year they're ready for a 'spankin' anyway. I just don't have the time anymore to constantly be out there pulling excessive shoots so I tame them back pretty good every couple years. Here's to a not too wet/not too dry spring!
