Dig post holes 3 feet deep and 8 feet apart. Use 4 by 4s, 6 by 6s or 6-inch-diameter round posts. Only use posts that have been pressure-treated with a wood preservative.
Set the posts in the holes and put about 6 inches of gravel in the bottom to enhance drainage. Add two or three shovels of soil to the holes and then tamp until the soil is firm. Repeat this process until the holes are filled and are even with the ground line.
Build two braces in each direction from the corners of wire fences. Install a post diagonally from the top of the corner post to the bottom of the adjacent post in the fence line. Double wrap a a 12-gauge smooth high tensile wire between the two posts in the opposite direction of the diagonal post. Build other braces in the same manner.
Use aluminum or hot-dipped galvanized 8d nails to fasten wood to a fence and fence staples to fasten wire. Tighten wire with wire stretchers
