For example, if you live in the North, the winter wheat and the winter rye are the popular options. On the other hands, if you live in warmer regions, crimson clover and oats are the popular choices. If you want to have a winter cover crop, you should sow after you have harvested the last crops. In the following spring, till the plants into the soil and add more organic matter.
