I am not really interested in recusing it size at this point but rather working on building the trunk up instead I bought the tree because I liked its size and basic structure. It is definatly a grafted tree right where the first branch comes out. I want to at least give if a year or two to try to work with things as they are before I go making any really drastic cuts. I may though turn it around and use what I had as the back for the front instead. In the spring I think i am going to plant it into a long shallod wooden box for a couple years unless I can do this sooner since I won't be reducing its root size?
OK, fair enough. Just realize: If you are going to grow out the trunk, you can pretty much give up on the branches that are there now: To get a thicker trunk you want to stimulate growth, resulting in fat branches. This will in the end result in you cutting of the branches and re-growing them.
You can easily transfer it to a shallow tray now; However, if you want to work on the roots beforehand (I would want to: You should untangle the roots, and plant them flat, radiation nicely from the centre, to create a nice nebari, or root flare. That can be a big blow to the tree, especially if your weather is better than ours (We are having 15 degrees and rain, up from 7 degrees and rain earlier this week). So no major root-work unless you want to risk loosing the tree (I still do rootwork in the middle of summer, but usually on treespecies I know)
