Sustainable Seed Company Organic Crimson Clover Seeds — 5 lb Bulk, OTCO Organic, Nitrogen-Fixing Cover Crop

Organic Crimson Clover seeds in a 5 lb bulk bag provide a fast-maturing, nitrogen-fixing cover crop that flowers bright crimson and supports pollinators.

These Sustainable Seed Company Organic Crimson Clover seeds (Trifolium incarnatum) are non-GMO, open-pollinated, and OTCO certified organic. With 70–90 days to maturity and roughly 232,000 seeds per 5 lb bag, they serve multiple roles: soil builder, pollinator attractor, forage plant, and an attractive addition to wildlife and deer food plots. The seed’s vigor, high germination, and versatility make it suitable from small gardens to acres of farmland.

How quickly will these crimson clover seeds establish and bloom?

Crimson clover typically germinates rapidly under the right soil temperature and moisture, producing lush growth within weeks and colorful flower heads in about 70–90 days. Planting time influences timing: late-summer to early-fall sowings often overwinter and bloom in spring.

• Germination: rapid when soil is warm and moist
• Maturity: 70–90 days to flowering
• Best sowing: late summer to early fall for spring bloom
• Flexible: can be used nearly any season as a companion or cover

What benefits does crimson clover bring to soil and subsequent crops?

Crimson clover fixes atmospheric nitrogen into the soil through symbiosis with rhizobia bacteria, enriching nutrient levels for the following crop without synthetic fertilizers. It also improves soil structure, increases organic matter, reduces erosion, and suppresses weeds while rooting through compacted layers to improve water infiltration.

• Nitrogen contribution: living fertilizer for following crops
• Soil health: better tilth, organic matter, and structure
• Erosion control: dense cover protects the surface
• Weed suppression: competitive ground cover reduces weed pressure

Can I use these seeds for forage, wildlife plots, or in mixes with grass?

Yes—organic crimson clover pairs well with grasses for hay and grazing, offering high-quality winter forage and spring regrowth. It’s also attractive to deer and pollinators, so it’s commonly included in food plots, pollinator mixes, and pasture blends to support wildlife and beneficial insects.

• Forage: winter grazing and spring regrowth when mixed with grasses
• Wildlife: favored by whitetail deer and other game species
• Pollinators: abundant nectar for bees and butterflies
• Mixing rates: integrates well at recommended seeding densities

How should I sow and how much area does a 5 lb bag cover?

Sow crimson clover at 1/2–3/4 lb per 1,000 sq ft (20–30 lbs per acre) for a dense stand. Broadcast, drill, or interseed depending on scale; lightly rake or roll to ensure good seed-soil contact and maintain consistent moisture until established.

• Rate: 0.5–0.75 lb per 1,000 sq ft or 20–30 lbs/acre
• Methods: broadcasting, drilling, or interseeding
• Seed-to-soil contact: light raking/rolling recommended
• Moisture: keep soil evenly moist until seedlings establish
