A trellis can be a beautiful addition to an exterior wall of your home. Trellises can be used for a variety of climbing flowers and are particularly useful with roses. Building and installing a trellis doesn't have to be an elaborate project. Most trellises have pre-drilled holes, and some even come with hardware to easily attach the trellis to a wall of your home. It doesn't take much to attach a trellis, as it only needs to support the weight of flower vines.
Cut nine 2.8 (1 1/8 inch) pieces off the PVC pipe. These will be the spacers behind the trellis. The space allows the vines to intertwine behind the trellis.
Hold the trellis against the wall. Have a friend place a level on the top and side edge of the trellis. Adjust it until it is level both ways.
Drill 1.5 mm (1/16 inch) pilot holes through the trellis and into the wall. Drill three evenly spaced holes across the top, middle and bottom of the trellis to create nine pilot holes for the screws.
Lay the trellis down against the wall. Have your friend grab a 2.8 cm (1 1/8 inch) PVC spacer and place it on the centre pilot hole on the wall. Position the trellis over the spacer and place the screw through the trellis and into the wall. Once you have the centre screwed in, you can slide each spacer in around the perimeter of the trellis. Place the remaining spacers in a similar manner.
