Building a trellis for your climbing roses provides you with a way to showcase your roses and add structure to your garden design. Utilising standard dimension wood, low-cost hardware and common household tools you can build a bentwood trellis for climbing roses. It may seem complicated at first but this low-cost woodworking project requires only basic woodworking skills and tools. Before the weekend ends your next project will be training your climbing roses to grow up a trellis of your own creation.
Place your 1-inch-by-10-inch-by-6-foot long board with the 10-inch face flat against your workbench. Mark a T (for top) on the top of the board and the mark the opposite end B (for bottom) with a pencil.
Use your measuring tape to measure 6 inches down from the top of the board and mark that measurement on both of the 1-inch sides with a pencil.
Place a 5/16-inch drill bit in your drill. Put on safety glasses. Drill a centred hole through the left 1-inch side through to the opposite 1-inch side with the drill.
Use your measuring tape to measure 12-inches up from the bottom of the board and mark that measurement across the 10-inch face of the board with a pencil.
Mark 19 evenly spaced lines from the 12-inch marking at the bottom of the board to the top of the board, approximately 1/2 inch apart. Use a table saw to cut along those lines creating the 20 vertical arms of climbing rose trellis.
Thread and centre a 5/16-inch-by-3-foot dowel in the 5/16-inch hole. Secure the centre arms to the dowel, approximately 1-inch apart, by hammering a 3/4-inch brad through the arms into the dowel.
Spread slowly and secure the left-hand side arms approximately 1 inch apart along the dowel with additional 3/4-inch brads. Repeat the spreading and securing process on the right-hand side arms.
Reinforce the rose trellis vertical arm placement by placing a small amount of wood glue along each connection with the dowel. Allow the wood glue to dry for four hours.
Spray the trellis with two coats of outdoor acrylic paint. Allow the paint to dry for 24 hours.
Plant the uncut 12-inch portion of the trellis in the ground behind your climbing roses.
Spread the 20 arms across the dowel slowly; too much pressure on them will make them break.
