Time of year is crucial. Now it's too late in the season to start the branching you're looking for. I'm going to follow the advice i was given at a bonsai expo. Trim in the spring, can't remember before or after the first flush. Then after it fills out after trimming, then feed/fertilize. Feeding ea...

woah, nice. I don't know much about em, but plants in general, i'd say, it got way too tall already and you don't wanna kill it, you may just need to loop it around, with 3d printed struts and lop off more towards the top so it can become a curlyQueue, but with more branching, haha!
