The only place I could plant it into the ground would be in full sun, and I am unsure of how well it drains in that area. And I will start with the fertilizer
The full sun could be a problem with leaf scorch, though I've noticed that the maples I have in the ground in full sun seem to deal with it a lot better than the maples in pots.
As for the drainage, why are you worried about drainage? Do you get standing water? My yard is full of the heavy Virginia red clay and trees I have in the ground (landscape and potensai) seem to do fine. I do amend the soil for my potensai though.
