Explore Windmill Grass Details: Uncover Windmill Grass Facts and Management Strategies

Windmill grass, a member of the Poaceae family, is a common sight in arid and semi-arid regions across the United States, Australia, and other parts of the world. This perennial warm-season grass, scientifically known as Chloris truncata, is known for its prolific growth and ability to thrive in nutrient-poor soil with plenty of sand, rock, or grit.

In its native range, windmill grass can be found in sandy ranges, barren wastelands, roads, lawns, and gravel areas. It grows between 6 and 18 inches tall and prefers arid, gritty zones with hot summers and plentiful spring rain. In the US, it is found from Nebraska to southern California. In very dry areas of the United States, windmill grass tends to seed and populate turf grasses, requiring intervention to protect chosen species.

The control of windmill grass is often necessary due to its aggressive growth. The seed head of windmill grass is comprised of eight spikelets that radiate out from a central stem, making it easy for the grass to spread. In its flowering phase, which occurs four to six weeks after germination, the flower heads are 3 to 7 inches across and start out reddish but mature to a beige or brown color.

In Australia, windmill grass is a widespread weed and can cause problems with livestock, such as liver problems and photosensitivity. Non-chemical options for windmill grass control in Australia include tillage and crop competition. In the US, maintaining healthy turf grass and sod can make windmill grass control easier. This includes annual aeration, consistent watering, and yearly fertilization.
