Crabgrass seed is an excellent source of food for both waterfowl and upland birds. It can also produce an abundance of ground cover for upland birds. This easy growing plant can grow in a variety of growing conditions ranging form moist soil to droughty dry. It's also a quick growing crop that matures in 60-80 days with little to no irrigation. Crabgrass has the ability to be flood irrigated and can handle being flooded for the fall and winter and regrow each year with a spring/summer draw down. All of these factors make it an ideal companion crop to go with other seasonal wetland crops such as Wild Millet, Pennsylvania Smartweed, and American Sloughgrass.
