Grain sorghum is native to North Africa, the Middle East, and parts of Asia. It has been introduced and is now cultivated in many regions across the globe, including parts of every continent except Antarctica. This wide distribution indicates its adaptability to various climates and environments. Its status as a cultivated species further signifies its integration into agricultural practices worldwide.

Grain sorghum, commonly known as grain sorghum, hails from Africa. The features that classify this plant as a potential weed include its sturdy structure and the ability to adjust to varying climates. Its rapid growth rate and hearty drought resistance make it tough to get rid of once it gets established, potentially engulfing other more delicate garden plants. Grain sorghum's harmfulness shines through as it can stunt the growth of other plants due to competition for nutrients, sun, and space. If you choose to grow this plant in your garden, be attentive to its rapid growth and spreading habits. Regular monitoring and pruning can help keep it in check. The primary method grain sorghum uses to spread is through its seeds. Wind, water, and animals can help distribute these small seeds over large distances, enabling grain sorghum to propagate even in new environments.

The best season to manage grain sorghum as a potential weed is before it reaches the seeding stage. For controlling the growth when cultivating grain sorghum, it's crucial to limit its spread before it matures and disseminates seeds.
