Winter King II alfalfa is an inexpensive variety ideal for the value minded grower with a three-cut cropping system. It not only delivers winter hardiness equal to Vernal Alfalfa, it also has disease resistance to Phytophthora Root Rot. In general, alfalfa is one of the highest yielding forage plants available. Where adapted, alfalfa does well alone or in a mixture with tall-growing grasses. Alfalfa produces best on well-drained soil with good water holding capacity and pH of 6.5 or above. It is long-lived and drought resistant.

Grower’s Note: This seed comes pre-inoculated with rhizobacteria. Alfalfa is a member of the legume plant family and forms a mutually beneficial symbiotic relationship with rhizobacteria in the soil. The bacteria help capture nitrogen from the air and makes it available to the plant roots, which improves overall plant growth. However, rhizobacteria is not always present in the soil, especially if the host legume has not been grown in the target area in the last three years. Therefore, this seed is pre-inoculated to jump-start that symbiotic relationship.
