Winter cover crops prepare the soil for spring and prevent winter weeds.
Winter cover crops differ from region to region, but from a management point of view, there are two types, winter-killed and overwintered.
Winter-killed cover crops are those that are planted in late summer or early fall with the expectation that they will die back in the cold of winter.
The dead plant matter will keep the soil covered, thereby suppressing weeds and providing dead plant matter for soil organisms to consume.
Overwintering cover crops are the opposite, they are cold-tolerant and can survive stretches of freezing temperatures (some like our FROSTY Berseem Clover down to -14 degrees F).
Overwintering cover crops are great for fixing soil Nitrogen for spring cash crops.
