Garden trellises are a necessity for many plants. Climbing ornamental vines as well as some vegetable crops require the support a trellis offers in order to grow well. There are two primary types of mounting for trellises—free standing or wall mounted. A free-standing trellis provides a place for plants to climb in the middle of the garden. A wall-mounted trellis is suitable for many ornamental vines, as it allows the plant to grow along building walls or fences.
Free Standing Trellis
Purchase a 2-by-2 inch stake for every 4 feet of trellis length. Use stakes that are 1 foot longer than the height of the trellis material.
Drive the stake 10 inches into the ground. Dig a hole of the proper depth with a post hole digger or pound the stake in with a rubber mallet, depending on how hard your soil is.
Set the trellis against the stakes so the top of the trellis is flush with the top of the stakes. Use either a wood or vinyl trellis board or trellis netting.
Nail the trellis to the stakes to anchor it in place. Use staples instead of nails with trellis netting. Use one nail or staple every 10 inches down each stake.
Hold the trellis against the wall in the area where you want to anchor it. Line the sides of the trellis up with a wall stud. Find nails or screws in the siding, which indicates where studs are, or use an electronic studfinder to locate the studs.
Mark the wall and the trellis frame with a pencil where each mounting screw will go. Place a mounting every 8 to 10 inches around the trellis frame so it doesn't pull loose from the wall under the weight of the plants.
Set the trellis aside. Drill a starter hole into the wall at each marking you made. Use a bit the same diameter or slightly smaller than the screws. Drill a hole completely through the trellis frame at each marking.
Set the trellis back against the wall and line up the holes in the trellis frame with the starter holes in the wall. Place a 1-inch length of ½-inch PVC pipe between the trellis and wall at the location of each hole. The PVC pipe holds the trellis away from the wall slightly so the plants have room to wind around the trellis.
Screw the trellis to the wall using 3 ½ inch screws. Position each screw so it passes through the trellis frame and PVC spacer, then into the wall. Repeat for each hole, then tighten the screws completely.
