Prairie Coteau Farm

Welcome!  We specialize in producing quality certified organic garlic seed and culinary garlic. Our 40-acre patchwork of rolling prairie, woods, fields and wetlands is located on the Coteau des Prairies, a long, high ridge in northeastern South Dakota. We, Nick Siddens and Kristianna Gehant Siddens, began Prairie Coteau as a Community Supported Agriculture (CSA) and market farm, but after several years of harvesting beautiful garlic for our CSA shares, we decided to focus our efforts there. Since 2004, we’ve tested over twenty varieties and continue to try different cultivars to provide our customers with great flavor and quality. We currently offer eight varieties of garlic and select our own seed from among our stock each year to ensure we offer you the best.  Seed companies, market farmers, home gardeners, restaurants, food co-ops and grocery stores comprise our diverse customer base. 

As a certified organic farm, we utilize practices such as crop rotation, cover cropping, mulching and rotational grazing to produce a healthy crop without synthetic herbicides, pesticides or fertilizers. We apply naturally-sourced minerals and amendments to encourage a well-balanced, biologically active soil. This provides fertility for our crop while reducing the incidence of pests and disease. Our garlic spends the winter tucked away under a thick mulch of native prairie grasses grown on our farm. Years ago we established several acres of perennial natives such as Big Bluestem, Indian grass and Switch grass for this purpose as well as to provide wildlife habitat and continuous soil cover on erodible areas. In 2016 we planted more acres of native grasses to improve the soil, capture carbon and provide pasture for our flock of Clun Forest cross sheep. Our goal is to use natural systems to our advantage in a holistic approach to stewarding our land.
