Organic Crimson Clover - Raw Seed (lb)

Organic Crimson Clover (Trifolium incarnatum) is a cool-season annual legume widely used as a cover crop to improve soil fertility and structure. It produces dense, fast-growing vegetation that helps protect the soil from erosion during fall and winter while adding organic matter when incorporated in the spring. Crimson Clover is well-adapted to a variety of soil types, though it performs best in well-drained soils with moderate fertility.

One of its primary benefits is nitrogen fixation. As a legume, Crimson Clover forms symbiotic relationships with soil bacteria, capturing atmospheric nitrogen and converting it into a form available for future crops. When mowed or tilled under as green manure, it releases this nitrogen along with additional nutrients, improving soil fertility and reducing the need for synthetic fertilizers. Its deep, fibrous roots also enhance soil structure, promote better water infiltration, and reduce compaction over time.

Crimson Clover effectively suppresses weeds by forming a dense canopy that limits light and space for competing plants. Additionally, its vibrant red flowers bloom in early to mid-spring, providing a valuable nectar source for bees, native pollinators, and other beneficial insects. This makes it a useful cover crop for vegetable gardens, orchards, vineyards, and crop rotations that benefit from improved soil health and biodiversity.

Application Rate:

• Broadcast seeding: 15–20 lbs per acre

• Drilled seeding: 12–15 lbs per acre

• Small areas: approximately 1 lb per 2,000 sq. ft.

For optimal results, sow in late summer or early fall to establish before winter dormancy.

Raw seed requires inoculant.
