Maybe you think that with the whole trunk being made of wood, it is hard to strangle a tree. Not so. Step one: Pick tree. Preferable younger. Like in the front lawn of a new house.
Step two: Put stakes around tree and tie it up to support it. Tie straps tightly around young thin trunk. See below.
Step three: Wait. Years is best. About three seems to work. When the tree doesn't look so good, wonder why.
(Optional Step four: Rescue tree. Show results.)
