Name: Michele Roth N.E. Indiana - Zone 5b, and F (Zone 9b) I'm always on my way out the door..
When I pulled my clump of 6 footers at the end of the season the root mass was fairly large but not nearly as deep as I expected it to be. You may want to add plenty of sand or gravel to the bottom of the pot though, mainly for heft and wind stability.
