I just bought a pre=Bonsai, Black Pine, not sure exact abe but it's called Size 1 where I got it. I'd like to make it the best Bonsai possible. It seems to have no possibilities, maybe because I'm a total newbie and have no idea what to do. It's still in it's nursery container, and is about 13" with a straight thin trunk and no side branches at all. At the top it has a healthy looking but? looks like a mini embryo pine cone, and around it has many long soft needles and some shorter stiff needles lower. I've searched but I haven't been able to find advice on what I can do to entourage any kind of side growth and branches. I fear it will grow too tall, it's too tall already, if I do nothing. So, any ideas about what I can do to lower the height and make it interesting? I've done no pruning of anything or any wiring, nothing, so far.
