What Is Cool Season Grass?
Cool season grass refers to turfgrass varieties that thrive in temperatures ranging from 60°F to 75°F (15°C to 24°C).
These grasses are ideal for regions with cold winters and mild summers, typically found in the northern parts of the United States, Canada, and parts of Europe and Asia.
Cool season grasses are most active during spring and fall and can stay green longer in cooler weather.
These grasses have adapted to grow quickly during cooler periods and go semi-dormant during the peak summer heat. Choosing the right cool season grass for your lawn involves understanding your local climate, soil conditions, and how much maintenance you're willing to perform.
