Temperature plays a critical role in seed germination. Soil temperatures must be at least 55 degrees Fahrenheit (13 degrees Celsius) for northern type turf grass seed to germinate (Bluegrass, ryegrass, fescue). Air temperature must typically be between 60- and 80-degrees Fahrenheit (15-26 degrees Celsius). Southern seed types (bermudagrass, zoysiagrass, bahiagrass, etc.) need soil temperatures of at least 70 degrees Fahrenheit (21 degrees Celsius), with air temperatures in the 80's or higher (21 degrees Celsius or above). Seeds will not germinate if the temperatures are cold at night or are fluctuating from high day temperature to very low nighttime temperatures. Very hot weather will also inhibit seed germination.
