I'm interested in this project as I do grow veggies every year. For the past few years I've only had 180 square feet of raised beds to grow my veggies in. Plus I place a couple of tomatoes in pots against the sunniest, warmest rock wall I have. We have rather cool summers here in Seattle, WA so often have what locals call a "green tomato year." However, with good planning its possible to get ripe tomatoes in cool years. Anyway, I digress from the main topic.
With only 180 square feet of beds, my main crop rotation has just been the tomatoes growing in the raised beds. The asparagus, strawberries, blueberries, raspberries and huckleberries are in additional permanent locations. And just last year I decided I wanted to try some specialty potatoes but didn't want to give up any of my raised bed real estate. A couple of "potato barrels" out on the hangar apron did the trick. (yes, we have a little Cessna in our attached hangar.)
Our local Master Gardener authority states, "The most critical rotations, in my opinion, are the onion family (onions, scallions, leeks, shallots and garlic) and the cabbage family (cabbage, broccoli, Brussels sprouts, cauliflower, collards, kale, kohlrabi, mustard, pak choi, radishes and turnips)."
