Alfalfa/clover will depend on your soil. A soil test would be very helpful. If you have a pH of 6.8 plus, and the soil is well drained, alfalfa would be a good choice. Clover can tolerate a pH to about 6.0, and moister (not wet soil) conditions. You can also lime the soil if you have a lower pH for alfalfa/clover. Winter wheat would be a better fall choice. Peas & oats mix would work great in early spring or fall.
