A garden trellis is a decorative yet utilitarian garden accessory. Although many climbing plants will also creep along the ground, if space is at a premium in your garden, training your plants to grow up a trellis helps free up space in the garden for other plants. You can purchase trellises in a variety of shapes and sizes; they are generally made from wood, vinyl or iron. Getting your trellis into the ground and ready for your climbing plants takes a bit of muscle.
Place your trellis in the north side of the garden and orient it so that it runs in an east to west direction. This will help avoid shading other plants.
Measure the distance between the two upright legs of the trellis. Place rocks or other marking devices on the soil, the same distance apart as the trellis's two upright legs.
Drive one post into the ground at the first marker. Use a heavy mallet or hammer to drive it at least 18 inches into the soil.
Drive the second post into the ground, at the same depth as the first, at the other marker.
Position the trellis against the posts with the uprights in front of the posts. Wire the upright to the post 3 inches from the top. Wire the bottom of the upright 3 inches from the ground. Repeat with the other upright.
