With a preferred pH of 5.0-7.0, buckwheat will grow in a wide variety of soils, but will not grow where wet. It will outcompete weeds in fields with high weed seed densities. Must be mowed/harrowed or otherwise incorporated before seed is mature; otherwise it may become a weed. For grain harvest, be aware that the grains (groats) do not ripen uniformly. Cut the plants when 80-90% of the seeds have matured (turned brown). There will still be green leaves and perhaps some blossoms at the top of the plant when they are cut. It is preferable to harvest the grain when ready, and not let the plant spend excess time standing as this results in high seed loss. Once threshed, remove as much green plant material as possible, as this can shorten the grain's life by overheating.
FOR GREEN MANURE: Till in at any growth stage.
FOR ORNAMENTAL USE OR GRAIN HARVEST: Cut the plants near the base when most of the green color has turned brown and the seeds are hardening (no longer milky).
