I have been doing square foot gardening for a few years and canning some of my harvest. I have Mel's original book and finally bought the most recent edition last year. Too much mud on the plant pages in the old edition! I have in place 12 boxes, 4'X4's, made from cedar 4X6X1s lined with weed cloth and filled with dirt, compost, and coarse vermiculite. It's good to have chickens and an equine buddy. About four years ago, I ripped up the front yard and put 2X4 boxes out there. Right now, spinach, Swiss chard, two kinds of lettuce and beans are in and growing. I have one bed dedicated to flowers for the bees. Back yard has one bed dedicated to some herbs (soon to change as I want them closer to the back door) and one for asparagus. I am slow this year due to three weeks of training in the middle of the spring planting season, but it's all good. Catching up will take a little while. But we have a long growing season, and the spring has been extended.
