This is what we call a Food tunnel! We built it today so that nature can take its course on it. Plants will grow on it and under it. It is held in place with T-posts and the hoop is made with 16 foot pig/cattle fence panels. The panels will serve as a trellis to the pole beans and sweet peas that are already planted. They will crawl and grow onto and over it and will also provide some shade to the underlying plants inside the tunnel. Food tunnels are a great way to maximize space by getting vertical and horizontal growing space. They are fun and beautiful too.
