Now following all your excellent advice, I culled my plants and put 20 or so in the ground. (Tachici, I'll send Hubby after those tubes, and next winter, lift the trees and do as you recommend, sounds brilliant to me, I was thinking of laying something to restrain the roots, but atm, don't have anything suitable. Everything that I put in is very young. Now the question is, I have 9 wisteria's and would love to put them in the ground, but I am concerned about the invasiveness of wisteria, and how large (Long?) should I let it grow? I do not have a lot of room in the yard at present.
