A garden trellis can be more than a way to support flowering vines, grapes or blackberries. It can also add dimension to your outdoor space. Make a decorative copper garden trellis, using plumbing supplies that you can paint to coordinate with your outdoor décor. Stand the fence-style trellis alongside a patio or as a border for a section of property. You can also use a trellis to separate tracts in your garden.
Measure and cut four seven-foot lengths of PVC pipe with a measuring tape and pipe cutter. These pipes are the vertical supports for the garden trellis. Measure and cut one nine-foot-long section of PVC pipe. This is the top horizontal support for the garden trellis. Measure and cut three three-foot-long sections of PVC pipe. These pipes are the middle horizontal supports for the trellis.
Swab the inside of one of the openings of one PVC elbow fitting with PVC primer. Swab the same primer onto the outside end of one of the seven-foot-long pipes. Wait 10 seconds. Cover the same areas with PVC cement. Insert the end of the seven-foot pipe into the elbow fitting and hold it together for 15 seconds.
Swab the inside of the second opening on the same elbow fitting with PVC primer. Swab the outside of one end of the nine-foot-long pipe with primer. Wait 10 seconds. Cover the same areas with PVC cement. Insert the end of the nine-foot-long pipe into the elbow fitting; hold it for 15 seconds.
Slide two slip-T fittings over the open end of the nine-foot-long pipe. Position the first slip-T fitting three feet from the attached elbow fitting. Position the second slip-T fitting three feet away from the first slip-T fitting. Repeat steps 2 and 3 to complete the outside frame of the garden trellis.
Slide a slip-T fitting over the open end of each of the seven-foot-long sections at the end of the nine-foot-long pipe. Position each slip-T fitting three feet from the elbow fitting.
Attach a three-foot-long section of pipe into the opening on the slip-T fitting attached to each of the seven-foot-long end pipes, using the same primer and cement process.
Slide one PVC slip cross fitting over each of the remaining seven-foot-long pipes that are not yet attached to the trellis structure. Connect a three-foot-long section of PVC pipe to the cross openings on each seven-foot-long pipe, using primer and PVC cement. This will join the two pipes together in an H formation.
Insert the top of the H formation into the two slip-T fittings on the nine-foot section of pipe, using primer and PVC cement.
Attach one three-foot-long pipe between the slip-T on the left vertical support and the remaining cross opening on the left side of the H, using PVC primer and cement. Attach the remaining three-foot-long pipe between the slip-T on the right vertical support and the cross opening on the right side of the H.
Insert the open ends of each seven-foot-long vertical support into the ground at least 12 inches.
