I use Bungee cords to hold all of my trees down, and since they are usually wired into the pots, so far (I am knocking on wood) I haven'y had any wind damage in many a year!
I might just add that when a tree is blown out of its pot, it is a good idea after replanting it back in the pot to soak the baby in water with some sort of a product like Roots2 to alleviate the shock!
Now you know why I use Bungee cords! A lesson learned the first year I started into Bonsai!
