A fan-shaped trellis can add an attractive note to your garden, providing a path for climbing ornamentals to cover. Fan-shaped trellises can be bought premade from garden and home-improvement stores, leaving the homeowner with only the issue of how to install the trellis. While you can simple dig a hole, shove the base of the trellis in and fill the hole, it's better to employ a method that will provide a more stable and long lasting mount.
Dig a hole measuring 1 foot deep with a shovel. The hole only needs to be about 8 inches across at the top.
Place a 2-by-4-inch board into the hole, extending vertically, with the 4-inch side of the board facing in the same direction as the planned broad side of the trellis. Place a level against the side of the board to ensure it's straight up and down. Fill in around the base of the board with dirt, tamping it down with your feet to ensure the dirt is solidly packed.
Paint or stain the board if you wish so it will match the trellis or background.
Drill two pairs of holes in the 4-inch side of the trellis. Space the holes 2 inches apart from each other straddling the centre line of the board. Place the first pair of holes 12 inches above ground level, and the second pair 30 inches above ground level.
Place the trellis against the board and push it firmly down into the ground. You can dig out a bit of soil for the base of trellis and back fill if you wish. Try to ensure the base of the trellis is about 4 to 6 inches in the ground.
Loop a zip tie around a centre portion of the trellis and through the holes at each pair of hole locations, closing the zip tie on the back side of the board. Trim any excess zip tie with a pair of scissors.
