Hi, all, I'm new to this board, and am looking for some help in designing a wire berry fence that will be in a 30 foot circle (95 feet circumference). What I am imagining are the forces on stretching wire around a curve, instead of a straight line, will slowly but sure pull the poles inward, and the traditional diagonal bracing won't help. Is it just a matter of putting the poles in so deep they won't pull inward, or am I missing something here? Trying to keep it as inexpensive as possible, not wood. Thanks very much!
