Warm-season grasses grow best during the warm months when temperatures reach 80 - 95 °F. in the spring, summer and early fall. They grow vigorously during this time and become brown and dormant in winter.

Cool-season grasses grow well during the cool months of spring and fall when temperatures average 60 - 75 °F. They may undergo stress, become dormant, or be injured during the hot months of summer and may require significantly more water than the warm-season grasses.
