Instead of putting it in the ground, or trying to put it in a box, I tried something a little different by building up around the roots..
The walls of this "pot" are made from sandstone pieces aligned in a circle. It was built up around the tree - this way, once it comes time to repot it, all I have to do is dismantle the stones...
I think the whole thing looks cool and little "mountainy"

The bottom of the pot was made from a terra cotta drip tray painted black and coated with schellac - holes were drilled into the bottom with a ceramic bit...
Of course this tree has a long way to go, and I'm glad to see it survive the winter. outside and completely unprotected...
