How to Build a Wood Lattice Fence

Pour 6 inches of drainage stone into the hole and tamp it with the post. Add or subtract stone to get your post height. Clamp two furring strips to adjacent sides to prop up the post in the hole, as shown. Tack a 1× scrap to the post's front face to stand in for the sleeve, and make sure it touches the mason line. Using a level on two adjacent sides, adjust the supports to make the post plumb. Add a few inches of drainage stone around the post. Pour dry concrete mix into the hole up to a few inches below grade. Add water until the mix is saturated, and stir it with a piece of scrap. Check for plumb, top off the hole with soil, and allow the post to stand undisturbed while the concrete cures.
