Crimson clover has a seeding rate of 12lbs/acre if i'm not mistaken. White clover is 8 lbs/acre, these are planted alone rates. Is this going to be a perennial plot? If not, I would leave out the white clover and chicory because they are perrenials and wont do much until spring. In other words are you going to plow this up in the spring and plant something else? If so leave the perrenials out.
