Looks wonderful, Dave. You're going to just love them. Lots of water and fert, and I'd imagine they'll take just about full sun up there in Tennessee. If you have room you can just winter them over in that pot, too. (indoors with the EE's of course)
I leave mine undisturbed for years unless somebody wants a start. Then when I go to dig a tuber, Wow. They really increase when they're happy.
