Spas are special features in the home landscape that deserve special treatment. Flowering shrubs, screened enclosures, arbors, trellises and statuary are a few of the ornamental choices to decorate. Whether your spa plans are simple or elaborate, your options include live plants and wooden structures. It's not difficult to build a spa enclosure as a weekend do-it-yourself project.
Paint all the wood and lattice pieces with weather-seal deck paint, before you assemble the wood structure, and let them dry thoroughly.
Measure 8-by-8-feet around the spa and mark four corners.
Dig 2 feet deep postholes (or holes as deep as the utility buckets) at all four corners, large enough in diameter to fit the utility buckets. Put a utility bucket into each hole and put a 1/2 inch of pea gravel in the bottom of each bucket.
Place a post in each bucket and fill the buckets with cement around the posts, ensuring they are straight and level.
Brace each post by screwing a 1-by-1-inch-by 4-feet length of wood horizontally across the front and back three feet from the ground for cross-bracing. Place a 1--by-1-inch-by 3-feet length of wood so that one end sits under each cross-brace and the other end touches the ground, bracing the post in a level position to dry. Let the cement cure for one day.
Screw two support boards to the outside of parallel posts 6 inches from the top of the posts and two support boards to the inside of the same posts, also 6 inches from the top. If you are working alone, use the clamps to hold them in place while you are drilling. These are the supports upon which the three 9-feet pieces of trellis will rest.
Place the three 9-feet pieces of lattice on top of the support boards, above the spa, and screw them in place.
Place an 8-feet piece of lattice on the outside of each corner post and screw them into place to complete the spa enclosure.
Attach hooks to the ends of the support boards for hanging plants. Make a larger enclosure for a larger spa with posts spaced farther apart and longer support boards. Use rounded posts and sapling trees for support beams for a rustic enclosure. Plant climbing plants like roses, honeysuckle, clematis, or grapes at the posts to grow up and over the top of the enclosure for a green, growing roof. You can plant gourds, pole beans, zucchini, and cucumbers to cover the trellises.
