I too have a bad back, so about 8 years ago we started collecting used " cattle troughs". We but old pots in the bottom to take up some of the space, then filled 1/2 with sand and the rest with soil, manure and compost. Each year the soil got better and better as well as the produce. This year I tried Zinnias as I could never get them to do much indoors. They are growing well and now I just have to transplant them in the flower beds. I take old plastic containers from plants I have bought and cut the bottoms out and use them as collars around the Zinnia's until they get bigger, and the rabbits leave them alone. I can sit on a bench and weed from the troughs and my back feels great!
