Annual ryegrass is a fast-growing, cool-season grass commonly used for erosion control, cover cropping, and as a forage for livestock. It thrives in a variety of soil types and can establish quickly, making it a popular choice for farmers and gardeners. This grass typically germinates in the fall and grows through the winter and early spring before dying off in the heat of summer. Its deep root system helps improve soil structure and prevent erosion, while its dense growth can suppress weeds, making it beneficial for sustainable agriculture practices.
