Buckwheat: Buckwheat is a summer annual broadleaf grain, and is used to produce food-grade flour and sometimes livestock feed. It thrives in cooler climatic conditions, but is not frost-tolerant. Buckwheat is fast growing and is probably best planted for production in early summer (after the last frost) or in late summer (about 8-10 weeks before the first frost) in North Carolina, although it can be grown anytime in the summer. The links from this page lead to production and marketing information for buckwheat. There is little information available on organic buckwheat production in the southeast, so adjustments to the management systems recommended must be made to fit NC's climate and into a certified organic operation.
