Life Cycle: Perennial

Grows best on deep, well-drained, friable soil with pH 6.5-7.5.

Plant alfalfa seed in clean, smooth, firm seedbed with adequate moisture. Ensure good surface drainage. Do not seed as first crop on newly leveled land where fill may settle and cause poor surface drainage. A combination drill and packer is desirable. Cultipack soil before and after seeding to help stand establishment.

Spring seeding can occur 30 days before last killing frost. Late summer-sown alfalfa seed can also be successful. Allow for adequate growth prior to first killing frost.

Rotational Grazing:

Graze early bloom (1/4 in. bloom) to 2 in. Potential bloat hazard. Use caution when grazing. Alfalfa best withstands grazing if rotated frequently or grazed in small strips.

Hay or Haylage Harvest:

Cut early bloom; last cutting should be 3-4 wks. before first killing frost.

Roundup Ready®:

To maximize benefit of Roundup Ready® alfalfa, apply glyphosate to alfalfa seedling at 3-5 trifoliate stage with weeds less than 4 in. tall.

ALWAYS READ AND FOLLOW PESTICIDE LABEL DIRECTIONS. Roundup Ready® crops contain genes that confer tolerance to glyphosate, the active ingredient in Roundup® brand agricultural herbicides. Roundup® brand agricultural herbicides will kill crops that are not tolerant to glyphosate.
