Think about what happens when we’re stretching tight wire fence across the farm. You can probably imagine that the wires create a tremendous pulling force on the fence posts at each end of the line.
Here’s video I shot a couple weeks ago as I was fencing the back pastures, showing the practical steps we take to brace the fence posts. As with most things, the little details matter. Failing to brace a fence properly, especially in a location with strong seasonal frost heaves, results in posts that work their way right out of the ground within a few seasons.
This sort of fence brace is called a floating brace. Traditionally, high tensile fences are braced with “H-braces”, an arrangement with two vertical posts, one horizontal post, and a diagonal strainer wire. But I’ve come to prefer these floating braces because they use less wood and only require one post at each end or corner. And, of course, because they hold up over the years!
