Exactly my point. If you build up your soil, no matter where you grow things, sufficiently with the nutrients the plants need, and that has nothing to do with whether you are growing perennials or annuals, you do not need to "rotate" your crops. In the average small urban yard you do not have enough room to do that properly anyway. Moving your tomatoes 10 or 20 feet will do nothing to protect them from pests or soil borne diseases since those pathogens will move that far on their own.
Never, ever should one develop tunnel vision that inhibits one to see what is obvious. If you "rotate" your annuals and still have pest and disease problems there is a reason and that has only to do with the soil. Conventional gardeners keep doing the same thing year after year and expect different results, that is insanity.

Farmhound, Thanks for your input and reminding the forum that all gardeners do not live in climates where winter,i.e.. killing freezes, keep pests/disease in check. A friend once told me that there was no need to argue facts. Southern gardeners need all the help they can get to grow organically and many of us know first hand the benefits of crop rotation. Bottom line: if you have good harvests without rotating your crops, good for you; if you have problems and are already doing soil building and using organic pest/disease management, try crop rotation too. In my experience, it works.
