Sorghum-Sudangrass Cover Crop Plant

Sudangrass likes the summer heat, yet it does well even with cold night temperatures. It is extremely drought tolerant as evidenced by the growth of over 7.5 feet tall during a drought year with only 1.2 inches of rain from mid-April to October.
It has a very active rhizosphere along with an extensive, fibrous root system capable of rooting 5.5 feet plus through hard clay subsoil. This rooting system makes Sudangrass an excellent host for building mycorrhizae populations.

Sudangrass was bred to have more leaves for higher nutritional value, but because of its ability to aggressively sequester nutrients, forages may be high in nitrates. When the first frost comes, it will winterkill and make prussic acid poisoning possible for animals. Minimize risk by waiting a few days after the first frost to resume forage harvest.

Sudangrass is a potential source of pollen and late season protein source for honey bees.
