Dig four 6-inch-wide holes that are 4 feet deep. You want about a third of the post placed in the ground. Two holes should be parallel to each other on one side of the path or walkway so that the space between them is 14 inches. Place the other two holes opposite the first two on the other side of the walkway.
Place 4-inch by 4-inch posts in the holes one at a time. Center the post in the hole and fill the hole with alternating 3-inch layers of dirt and crushed gravel. Pack each layer before adding the next. Use 12-foot 4-inch by 4-inch posts so the height of the arbor will be 8 feet.
Nail 7-foot pieces of 2-foot-wide lattice to the posts on one side of the walkway. Place the lattice on the outside of the posts, away from the walkway. Use 10d nails to tack the lattice to the post. Repeat the process with the other two posts on the opposite side of the path.
Measure the space between the posts across the pathway. Mark a third piece of lattice with this measurement and use a square to make a straight line. Cut the third piece of lattice to this length. Use a handsaw. Tack the lattice to the top of the posts.
Things You Will Need
- Post hole digger
- Measuring tape
- 4-inch by 4-inch posts
- Crushed gravel
- 2 7-foot by 2-foot lattices
- 1 4-foot by 2-foot lattice
- 10d nails
- If you want to add a finishing touch, cut some wood trim to the length of the lattice pieces and nail it over the outer edges of the lattice.
