Crop Rotation

crop rotation

Rule one of successful sustainable farming: ROTATE YOUR CROPS EVERY SEASON!

Why rotate your crops?

  1. Because you are smarter than the bugs! If you change the menu every season, last year’s bugs will always starve this year while your new crops grow.
  2. Because different plants need different nutrients. If you grow the same crops every year, you will exhaust your soil.

So rotate your crops every planting season. This means, every season, choose a crop from different family than the crop you planted this season. Never plant from the same family in the same field one season to the next. Ideally, leave three seasons between crops from the same family in the same field.
