Found this little seedling in my dads yard around 10 months ago. Obviously I want the trunk to be much larger than it currently is and because I dont have a good area to plant it in the ground I will make a box and repot at the appropriate time. My main question is do I repot in late winter? Also, Should I prune anything off? like those branches on the inside of the curves that will not be wanted in the design or should I just leave it alone because more branches equals thicker trunk faster? I did a little prunning a couple months ago and you can see the first branches new growth. I should have cut it closer to the auxiliary bud because if I was ready to build the branches by making the cut where I did I feel would have put me back (time wise) since I wasted trees energy since it will need to be cut back further down next time for better ramification when if done properly the first time ...
