1. With a bolt cutter, cut a section of cattle panel approximately 8 feet long.
2. Measure and mark two lines—one on each side of the center point and then 6 inches from it.
3. Using a plank—like you would when growing tomatoes using the tomato cages—bend the panel along each line. The bends can be slightly wider than a 90 degree angle, resulting in an arch that is a few inches wider at the base than at the top.
4. Cut the horizontal wire from both bottom edges—leaving wire stubs that can be used to anchor the trellis to the ground.
