Because plants can be grown very close to each other in a raised bed, even a tiny yard can support a lavish edible garden. The four 6-by-4 foot beds in my small herb garden, pictured here, produce copious quantities of parsley, thyme, and other aromatics. I pick these herbs at the peak of their perfection, then freeze them for winter use. A raised bed vegetable garden has less weeding, less bending, and absolutely no tilling—there are really no negatives to this type of gardening. Well, none that I can think of, anyway.
