Outsidepride Sunn Hemp Seeds 10 lb — Fast‑Growing Annual Legume, High Biomass for Cover Crop & Soil Improvement

Outsidepride Sunn Hemp Seeds are a fast-growing, high-biomass annual legume used as a cover crop and forage to improve soil fertility and control erosion.

These 10-pound Sunn hemp seeds from Outsidepride establish quickly and produce significant above-ground growth and root development, making them a practical choice for farmers, gardeners, and land managers who want to build organic matter, add nitrogen, and suppress weeds without turning the soil. Sunn hemp adapts to warm-season planting and performs well in hot, dry summers, producing tall plants with abundant seed and flowers that support soil structure and wildlife habitat.

How fast does Sunn hemp grow and how much biomass will it produce?

Sunn hemp is noted for rapid vertical growth and heavy biomass accumulation. Under favorable conditions it can grow about a foot per week and reach multiple feet tall within a few months, delivering more organic matter than many common cover crops.

• Typical growth rate: ~1 foot per week under warm, moist conditions
• Reported biomass: over 20% more than crimson clover or hairy vetch in comparable trials
• Typical mature height: 3–9 feet depending on fertility and moisture

What soil benefits and nitrogen contributions can I expect?

Sunn hemp fixes atmospheric nitrogen through its roots and builds soil structure with substantial root mass. When incorporated or terminated, the plant returns nutrients and organic matter to the soil, improving fertility for the next crop cycle.

• Fast nitrogen addition: can supply significant N within 60–90 days
• Improves soil tilth and increases organic matter when mowed or incorporated
• Suppresses many weeds by shading and quick ground cover

How do I plant and manage Outsidepride Sunn hemp for best results?

Plant sunn hemp when soil temperatures are consistently above about 50°F and avoid tight spacing that causes lodging. It performs best with good drainage, moderate fertility, and 6-inch or wider row spacing to maintain upright growth.

• Planting window: spring through summer in warm regions
• Soil pH range: tolerates pH 5.0–7.5; prefers well-drained sites
• Row spacing: 6 inches or wider recommended to reduce lodging
• Termination: mow, roll, or incorporate before seeding or when desired biomass is reached

Can Sunn hemp be used as forage and how does it fit into animal systems?

Sunn hemp offers forage value and can be grazed or harvested for livestock when managed properly. It provides nutritious above-ground material, but as with any forage crop, monitor maturity and introduce gradually into feeding programs.

• Suitable for grazing: when plants are at a vegetative stage and palatable
• Useful for diversified systems: supports poultry, deer plots, and other livestock feed
• Considerations: avoid overgrazing and follow gradual introduction to diets
