The idea behind square foot gardening is that you can plant fruits, vegetables and flowers in raised beds, above infertile soil and even out of the reach of pets. Seeds are planted in 1X1 square foot plots, and when harvested a new plant is installed in the square. Raised beds can sit directly on the ground, or include a bottom layer and be placed on patios, decks or porches. Because of a bad back, and a dog with a propensity to dig up our new plants, we decided to build a 4×2 foot table-top design.
