Construct a lattice trellis to support flowering vines, such as roses, clematis, and wisteria, or for vegetables, such as peas and beans. A simple prefabricated wooden lattice-work trellis looks decorative and enhances the appeal of any garden or backyard spot. Depending on personal taste, install your trellis on the ground, or suspend it in front of a fence or wall to add color to a bare spot. In time, the climbing vines will cover the panels of the trellis to display a vibrant burst of color, forming a natural screen.
Place the 4x8-foot lattice sheet on a flat area. Decide the trellis height and width, depending on the available space. A height of 5 or 6 feet should provide growing vines ample area to spread. Measure 6 feet on the panel and mark the spot. Extend it to the other end to form a straight line. Saw the excess off carefully.
Secure miter-cut molding strips over a long edge of the lattice sheet by hammering in 1-inch wire brads every 4 inches. If the edging falls short, position another length flush against its end and hammer in place. Saw excess off. Also attach molding strips to the remaining edges of the lattice sheet.
Dig a 2-foot wide hole over the selected spot with a post hole-digger. Level the base so it is even. Dig a second similar-sized hole 4 feet away from this one. Also level its base.
Stand an 8-foot 2x4 into one of the 2-foot deep holes. Ask a friend to help you with the heavy post. Mix concrete with water (follow label directions regarding specific amounts) and pour the mixture into the hole, around the post. Stop an inch or two below the rim.
Stand the second identical post into the other hole, and pour concrete around it, so that 6 feet of both posts will now be visible. Allow the concrete to dry thoroughly. Add soil over the dried concrete until in line with the surrounding soil level.
Install three fence brackets on the inner edges of each wooden post. To do this, measure and mark three equidistant points on each post, with one several inches below the top, the second located in the middle and the third several inches above the ground. Align the points to form a straight line in the center. Drill each bracket in place on the post with screws.
Hold one side of the lattice sheet, and ask a friend to grasp the other side. Slide it simultaneously into the brackets on both parallel posts, until it rests firmly on the lower flanges of the bottom bracket.
