Twine and zip ties were my old patio trellis, then I measured the sag
I used to string tomato vines up with whatever I had, zip ties and old twine, and every August the whole thing drooped into the dirt by the fence line. Last spring I finally built a simple wire grid on wooden posts, cost about $40 in materials, and now the plants stand straight even after a heavy rain. Has anyone else switched from improvised supports to a real structure and noticed how much less time you spend fixing things?
