Buckwheat is an ancient foraging crop that has been cultivated for thousands of years. It has become a popular cover crop for its ability to feed pollinators, scavenge nutrients, improve soil structure and smother weeds. Plants establish very quickly and can reach two to three feet tall in under a month. Brittle tops break down quickly when tilled, adding organic matter and improving soil tilth. Buckwheat cover crops should be mowed or tilled no later than 50% bloom or 10 days past first bloom to prevent seed set. Buckwheat can be planted from March 1 to August 31. However, the plants are frost-sensitive and will be killed when exposed to freezing temperatures. Some growers plant two successive crops to utilize the entire growing season and maximize their benefits.
