Rye, vetch, ryegrass, and fall-sown grain crops are often seeded with crimson clover. Such crops are seeded at half to a third the normal rate, and the crimson clover is seeded at half to two-thirds the normal rate. Seeding is done at the same time, but, as a greater depth is required for most of the seed of the companion crops, two seeding operations are necessary.

Farmers often use a mixture of 5 pounds of red clover and 10 pounds of crimson clover per acre with excellent results. The first growth of the mixture may be grazed or harvested for hay or for crimson clover seed, while the second crop is wholly red clover. Dixie crimson clover has given good results when planted with Johnson and Bermuda grasses.
