Query: The Ultimate Guide to Vegetable Gardening

In a way I wish this had been available when I first started gardening, but I'm not sure I'd have been open-minded enough to accept it then. I cut my teeth on Ortho's very basic (and inorganic) ALL ABOUT VEGETABLE GARDENING. Dick Raymond's JOY OF GARDENING opened my eyes to new possibilities. Then I read (and tried) Mel Batholomew's revolutionary SQUARE FOOT GARDENING. But, at least for now, CUBED FOOT GARDENING is the ultimate, the gardener's equivalent of the physicist's elusive "theory of everything." And it's so simple! It makes me wonder why I didn't think of this myself.
