I mix my seed to save money. I planted 6 to 7 acres of winter rye and wheat week before last. I bought a 1000lbs of wheat from a farmer for $70 and the winter rye I bought at our local co-op for $9 a 50lbs. On another spot I hunt I planted Buck forage oats and winter rye, that spot total about 3 acres. This weekend I'm planting about 2 acres total in three different spots on another place, these are located in the woods, makes for nice bowhunting.
