How do you keep a tree from falling over?

I do a lot of gardening in my yard and the best way I found to keep my trees falling over was if you get 3-4 long, thick sticks and put them in the ground pretty deep and tie them around the tree. If you have a smaller tree than you don't necessarily need really thick sticks. You can get these sticks from a local hardware store.
