How do you rotate crops in a home garden?
I'd like to do more rotation of crops in my garden putting brassicas where tomatoes grew last year, etc. However, with limited space, there's only so much I can do. I'm not sure how much it will help to have tomatoes growing 10 or 20 feet from where they're growing now, and it would be way too much work to maintain separate gardens that are far physically separated.
How do you rotate your crops, and how effective is it for pest control and nutrient renewal?
