I just read the the thread on "Fall Work" and have to say that I too along with most of you who subscribe to the method of Boons way and so many other noteable artists, find that their way is probably the best way for maintaining a JBP.

Here's a few pics of one of my raw materials that was given to me back in 2009, so the progression isn't that long but the outcome is really good I feel for such a short time of work. They should post in order from beginning till today after the fall work was completed.

I'm still debating on that lower left branch as to whether or not to keep it. I'll probably wait a few more years just to see where the tree will be at that time. Will be looking for a different pot also as this one is mainly for training. I'll also have to be careful not to let it get too full of foliage for that thin trunk.

Nice progression, I like this tree in progress.

You should keep the lower left branch at least for 3 or 4 years to help thicken the base of the trunk. Choose a secondary branch on that first lower left branch and tag it so you don't 'forget' and cut it off. Let it extend, for several years as an escape branch. It will look awkward, but  it will nicely thicken the first segment of the trunk. I would try to let the escape branch extend out at least 3 feet or more.

Good Job!  Nice progression over 3 yrs, nicely balanced.
