- Description
-
Known by numerous common names which depend on its location, sorghum is a crop grass native to Africa in the Poaceae (grass) family. It has been cultivated for over 3,000 years in southern Africa regions. It grows all over the world and is known for its ability to grow in drought laden poor soils. They prefer highly fertile moist soils with good drainage. It is grown as an annual in cooler hardiness zones and as a perennial in temperate Zones 9 through 12.
Several varieties of sorghum bicolor exist. Grain sorghum is used for food while grass sorghum is grown for use as animal feed. Broomcorn, as the name indicates, is used for making brooms. White sorghum is sweet and most used as a grain crop. Red sorghum used in the prodcution of beer, has a less sweet taste that makes it undesirable to birds.
Typically an annual, some varieties are classified as perennials. Included in the species of Sorghum bicolor are cultivated varieties as well as semi-wild weedy plants. The wild varieties have a ring of long hairs at the nodes. Their spreading branches are whorled.
Insects, Diseases, and Other Plant Problems: Aphids, American bollworm, and borer are common insects. Commonly affected by fungus, bacteria, and nematodes, these diseases can easily spread to crops. Birds and rodents are attracted to the seed heads, and can become a nuisance. It is aggressive, rapid growing and can outcompete other plants.
