I was just reading in another group where crop rotation for the home gardener really doesn't help much in preventing plant diseases. The reasoning behind this thought is that the average home gardener simply can't move his crops far enough away from where they were planted the previous year. The article stated that you need to move your crop at least 1/4 mile away because it's likely that the soil will be diseased up to that distance. One guy in the group said he has been planting his tomatoes in the same spot year after year for many years now and can see no difference. Others in the group also confirm this and state that they get a good crop every year as long as the soil is properly fertilized each year. Seems to make sense to me. Your thoughts on rotating crops a very short distance compared to no less than a 1/4 mile from where they were grown last season :)
