If you want to grow a bushier tree cut it back to waist height and then pick 3 or 4 branches to keep after they sprout out and harden off. If you want a standard just start tipping it where you want the branching to start. I grow bushes because I have space constraints. You can shape it however you want. You can tie it down, use weights, build a trellis for espalier or tatura, or you can let it grow straight up like a tower hahahaha. The options are endless.
