Buckwheat is a summer annual with extremely rapid growth; it can reach maturity in 70-90 days. It is frost sensitive, so it needs to be seeded in a timely fashion to allow enough growth before the frost date. Buckwheat is unique in its ability to make phosphorus and possibly other nutrients more available to the cash crop. It is used to condition topsoil, rejuvenate overworked poor fertility land, weed suppression, and to attract pollinators. Buckwheat is a component in most of our summer mixes and some of our early fall mixes.
