What Is the Difference Between Cool-Season Grass and Warm-Season Grass? Explained in One Article

Grass generally refers to herbaceous plants, and the corresponding concept is woody plants. People usually call herbaceous plants “grass,” but grass is divided into cool-season grass and warm-season grass. So, where do the differences between cool-season grass and warm-season grass lie?

Difference one: different growing temperatures

The suitable growing temperature for cool-season grass is between 15°C and 25°C, and when the temperature is above 30°C, growth is slow. The most suitable growing temperature for warm-season grass is 26°C-35°C, and when the temperature is below 10°C, it enters a dormant state.

Difference two: different growing seasons

Cool-season grass grows vigorously in spring and autumn, and is not tolerant of heat in summer; when the hot summer arrives, cool-season grass enters a stage of unsuitable growth. Warm-season grass grows luxuriantly from summer to mid-autumn, and is not tolerant of cold in winter; when late autumn or winter arrives, the aboveground stems and leaves turn yellow and wither, and the underground rhizomes are in a dormant state.

Difference three: different suitable regions

Cool-season grass is suitable for planting in regions with a relatively cool climate, such as Hebei, Shanxi, Shandong, Anhui, Shaanxi, Liaoning, Jilin, Gansu, and others. Warm-season grass is suitable for planting in regions with a warm climate, such as Hubei, Hunan, Henan, Jiangxi, Jiangsu, Zhejiang, Guangdong, Fujian, Sichuan, Chongqing, and others.
