Garden trellises supply support and structure to climbing plants such as ivy, honeysuckle vines and climbing jasmine. Although traditional trellises are made of wood, these trellises are temporary and can begin to deteriorate within a year. If you live in a particularly moist climate, consider building a more reliable and longer-lasting garden trellis from PVC or plastic pipe. Plastic components are nonorganic, which means they will not break down from outside conditions. On average, a plastic trellis can last 20 to 30 years.
Measure and cut one of the PVC pipes in half using the jigsaw, making two 2-1/2-foot pieces. Slice the pieces in half lengthwise so you have four half-pipe pieces.
Slice the other PVC pipes in half lengthwise so you have four 5-foot half-pipe pieces.
Line up three 5-foot pieces and position the four half-pipe pieces perpendicularly on top of them to form a lattice design. Leave two feet at the bottom of the trellis so it can easily be placed in the ground.
Place a screwdriver bit onto the power drill and screw the pipes into position from the back. Use two screws on the end of each pipe piece. The screws should be positioned at each point where the pipes intersect, with the two screws positioned one inch apart.
Drill 18 holes into the last 1-1/2 feet of the trellis using a 1/4-inch drill bit, spacing them one inch apart and moving in a circular motion around the trellis base. The holes will fill in with dirt during installation and while the trellis settles and aid in anchoring the trellis.
