Image via WikipediaI splurged and bought a self-watering plastic patio garden container at Lowes. It seems like it will work well for things like tomatoes and peppers. It even has wheels! The price was right. The directions recommended adding a little dolomite to the potting soil so I am going to try that. I think it will grow about 4 tomato plants in the one container. When I was young we had a large garden and I would just about overdose on tomatoes, cukes and strawberry s.
