We’ve all heard of the benefits of crop rotation in large scale agriculture. And we all know that those benefits can transfer to our home gardens. Even the smallest of gardens can benefit from crop rotation, even if crops are only moved a few feet each year. Crop rotation is especially important to the organic grower because it precludes many of the problems that lead to the use of chemical pesticides and herbicides.
Exactly what are the benefits? Rotating crops is especially critical to preventing disease from getting a foot hold on certain vegetables you might plant. The bacteria and spores that attack specific plants can survive winters and infect those plants again the following year. The good news is, once in the soil they can’t travel far. You’ll do more to move them around with your spring cultivation than anything they might do on their own. If you plant the same hosts that those diseases are looking for, you’ll provide them with the ability to re-establish and become even more severe. Plant something from another group of vegetables that don’t normally host the problems, and they’ll eventually disappear. (more…)
