Spread powdered chalk over the area you want to enclose, and measure it to give you an idea of how much wire you need. Also mark locations for wooden posts, spaced every 7 to 10 feet apart. Divide the total area you need to cover by the desired post spacing to calculate the number of posts you need for the project.
Dig a hole over each marked spot for the fence posts using a post hole digger. Keep the post 2 feet deep and slightly wider than the posts. Collect the dirt in a wheelbarrow or pile in a mound nearby.
Mix concrete with water in a wheelbarrow, enough for one post at a time, according to the product instructions. Use a trowel to mix the concrete with water until it's a workable consistency.
Add a few inches of concrete into the hole and level it. Enlist someone to stand a post vertically into a hole while you add concrete around it until it's several inches from the top. Level the top of the concrete with a trowel. Check the post is level and plumb, or correct immediately before the concrete cures. Repeat the procedure of installing the remaining fence posts.
Cover the concrete in each hole with dirt when it cures. Tamp the dirt with the back of a shovel until level with the surrounding.
Unroll a length of welded fence wire and place bricks or rocks on it to flatten it out. Stand the fence against a corner post. Pull wire taut around the corner post and attach it using galvanized staples. Enlist your helper to hold the wire against the post while you insert staples along the top, middle and end of the wire. Also insert additional staples throughout to prevent the welded wire from unraveling.
Extend the wire to the adjacent post, pulling it taut as you walk towards it. Repeat the process of securing the wire to the post, and the remaining posts, with staples. Splice two rolls together if one falls short at any point. End one length of wire at a post and begin a new length of wire at the same post. Cut excess wire using wire cutters.
