Hate to say it, Ethelean, but
Hate to say it, Ethelean, but your "practice" proves the rule: crop rotation is essential to success. It's probably small consolation now but we have a feature—and very helpful chart—on crop rotation in the 2014 Old Farmer's Almanac, which will be available for purchase in most place by end of August, everywhere in September. In the meantime, put this behind you and patronize local farmers markets.
