Sorghum thrives in well-drained soils with a pH range of 6.0-7.5 and requires full sun for optimal growth. It can tolerate a wide range of soils, including sandy or clay soils, but performs best in loamy soils with good fertility. Sorghum is a warm-season crop and requires a minimum soil temperature of 60°F for germination. It is drought-tolerant and can grow in areas with low rainfall, but it also benefits from regular irrigation during dry periods. Soil preparation should include weed control measures, and adequate nutrients, particularly nitrogen, should be provided for optimal growth and yield.

After danger of frost has passed, sow seeds 4" apart, 1/2" deep in rows 30" apart. Under ideal conditions, germination will occur in 7-10 days.  Once seedlings are established, thin to one plant every 8".

Insect Pests

Common pests of sorghum include the sorghum midge, lesser cornstalk borer, fall armyworm, headworms , chinch bugs and stink bugs. Rotating crops and practicing proper tillage and/or fall cleanup can prevent infestations and keep populations at bay.

Diseases & Other Problems

Sorghum is susceptible to various diseases, including anthracnose, grain mold, and smut, which can cause severe damage to the plant. Other problems that can affect sorghum include nutrient deficiencies, weed competition, and environmental stress. To prevent and manage these issues, it is essential to maintain proper plant health by providing adequate nutrition, irrigation, and pest control measures. Crop rotation and selecting disease-resistant varieties can also be effective strategies to minimize the impact of diseases and other problems on sorghum crops.

Cane sorghum to be used for syrup is usually harvested when the seeds reach the hard dough stage, which typically occurs the seed heads start to change from white to amber. At this point if you pinch a seed between your fingers, you shouldn’t be able to crush it. For grain sorghum, or syrup varieties that are being grown for seed, harvest typically occurs when the seed reaches physical maturity. At this stage, the plants will be a dusty green color and the heads will be dark amber brown. Cut the plants about 1ft below the head and store the seed heads right side up in a bucket or tote until they are totally dry. Avoid threshing the heads until they are completely dry or the seed will mold. To remove the seeds, rub the seed head between your hands to release the seeds. Winnow to remove any debris and store in an airtight container.

CONSIDERATIONS:

Sorghum is an inbreeding plant, with self-fertile flowers that typically self-pollinate. Cross-pollination is technically possible but is rare. To ensure varietal integrity, bag heads prior to pollination using waterproof paper pollination bags or mesh bags. Bags can also be left on until harvest to minimize bird predation.

HARVESTING SEED:

Wait until plants reach physical maturity and the seeds have turned a dark, amber brown color. Cut the plants about 1ft below the head and store the seed heads right side up in a bucket or tote until they are totally dry. Avoid threshing the heads until they are completely dry or the seed will mold. To remove the seeds, rub the seed head between your hands to release the seeds. Winnow to remove any debris and store in an airtight container.

SEED LONGETIVITY:

Sorghum seeds remain viable for four years if stored under ideal conditions.
