Buckwheat VNS Summer Cover Crop - Organic

Certified Organic.

Buckwheat (Fagopyrum esculentum) is a fast-growing, broadleaf annual renowned for its dual-purpose applications as both a nutrient-rich grain crop and an effective cover crop that is great for pollinators. Its seeds are utilized in various culinary dishes, offering a gluten-free alternative rich in protein, fiber, and essential minerals. However, buckwheat's prominence shines as a cover crop due to its rapid growth, weed suppression capabilities, and soil health benefits. It establishes quickly, creating a dense canopy that outcompetes weeds, prevents soil erosion, and enhances soil structure. Its abundant flowering also attracts pollinators, contributing to increased biodiversity. Buckwheat thrives in low-fertility, well-drained soils and is particularly valuable in crop rotations for its ability to scavenge residual nutrients, making them available for subsequent crops. Its short life cycle allows for flexibility in planting schedules, fitting well between main crops or during fallow periods to maintain soil cover and fertility. Buckwheat is one of the best summer cover crops.

To utilize buckwheat as a cover crop, sow seeds directly into well-drained soil after the last frost when soil temperatures reach 55°F or higher. Broadcast seeds at a rate of 50–60 pounds per acre and lightly incorporate them into the top 1–2 inches of soil, or drill at no more than 1". In a garden buckwheat can be scattered on loose soil at a rate of 1lb/250 sq ft and raked in or shallowly rototilled in. Buckwheat germinates rapidly, often within 3–5 days, and reaches flowering in 4–6 weeks. For optimal soil benefits, terminate the crop at full bloom by mowing or cutting before seeds set, approximately 7–8 weeks after planting. The residue decomposes quickly, so incorporate immediately after termination for optimal enriching of the soil with organic matter and nutrients. Avoid planting buckwheat too late in the season to ensure adequate growth before the first frost. When grown as a grain crop, allow seeds to mature fully before harvesting, typically 10–12 weeks after planting.

The Midwest, with its unique combination of diverse topographies, microclimates, soil types, and weather patterns, presents a distinct set of growing challenges. At Driftless Seed Supply, our deep understanding of these conditions, honed by years of experience as Midwest growers, informs every seed we produce.

Generations of seed production, coupled with rigorous trialing in partnership with regional farmers, have enabled us to offer seeds that are exceptionally well-suited to the Midwest's unique growing environment.

Our commitment goes beyond just supplying seeds. We strive to ensure that Midwest farmers and gardeners like you have access to seeds that are not only well-adapted to our region but also capable of producing outstanding yields. Each generation of seeds we cultivate here in the Midwest—rather than in distant, climatically different regions—enhances the adaptability and performance of our varieties, setting them apart from those offered by many other seed companies.

Additionally, our collaboration with small local farms for most of our seed production is a testament to our dedication to strengthening the Midwest's food system. This approach not only supports local agriculture but also avoids the need to rely on large-scale production facilities in distant locations, whether out West or abroad.
