Turfgrasses perform more effectively within temperatures that most closely match their growth patterns. Turfgrasses are divided into two temperature categories: cool season and warm season.
Cool-season turfgrasses are those species with optimum growth at temperatures between 60 and 75°F (15.5 to 24°C). Cool season grass species include creeping bentgrass, fine fescue, tall fescue, Kentucky bluegrass, annual ryegrass and perennial ryegrass.
Warm-season turfgrass are those species with optimum growth at temperatures between 80 and 95°F (27 to 35°C). Warm season grass species include Bahiagrass, Bermudagrass, Bentipedegrass, St. Augustine and Zoysiagrass.
