I found this JWP at a nursery and fell in love with it. The problem is that I am not sure of its bonsai potential. It is about 4.5' tall and most of the lower branches have died off. I've never worked with this tree before so I am not sure what I could get away with if I tried reducing its height. Could I cut it back a little at a time over a few years? Would this stimulate any back-budding? Sorry for the poor quality - All I had was my cel phone camera.
