Hold the shepherd's hook upright in the desired spot for securing the spikes in the soil, preferably on level ground.
Rotate the iron rod so the hook or hooks at the top are facing in the desired direction.
Place your foot on the flat iron bar above the two ground spikes as though the bar is a step. Push down on the bar with your foot to drive the spikes into the soil until the bar is pressed against the ground.
Hang plants or decorations on the iron hooks at the top.
