Marathon Red Clover

Marathon Red Clover is a strong 3-4 yr perennial red clover cultivar developed by The University of Wisconsin. Yields are most pronounced in the second and third hay/grazing years. Marathon is resistant to bean yellow mosaic virus and northern anthracnose. Marathon is best adapted to the northern half of the United States.
Marathon is also used as a compliment in pasture blends and in wildlife food plots. Red clovers are one of the fastest establishing legumes and can even be grown on more acidic soils.

Marathon Red Clover is pre-inoculated with an OMRI listed inoculation for improved establishment and growth. Inoculation is recommended when planting legumes.
Coatings are beneficial for better seed coat protection and easier planting.
*Details on seed coatings, inoculations and our OMRI certificate is available on our Resources Page.

OMRI Listed



Plant at 1/4″ depth. An ideal soil bed is moist, fertile and firm. A soil test is recommended for proper plant establishment and growth. Red clovers can be planted, broadcast or frost-seeded successfully.


Graze or cut for hay when the red clover is ¼ to ½ in bloom. A second cutting or successive grazing should occur when red clover is ¼ in bloom. Leave at least 2 to 3 inches of growth after each harvest. Care should be taken to eliminate or appreciably reduce bloating of livestock when grazing. Keep lime and fertilizers (phosphorus and potash) at the proper level.
