We just moved into this house that is beautifully landscaped. I think this tree is right next to the front door. It is about 6", mostly droopy, but has a couple of branches at the top that are sticking out straight. How do I train it so the branches don't stick out, or do I trim the branches off? From reading about this variety it sounds like they can get quite big. Given it's location that would not be a good thing. How do I keep it a manageable size?
