One big difference between heat stress and cold stress is cold stress can have an impact on warm season turfs AND cool season turfs. Whereas heat really only affects cool season turfs. Warm season turfs usually thrive in warm weather. As logic might dictate, cool season grasses are a little more tolerant of cold temperatures than warm season grasses.
As I’ve said many times in this blog, you got to select the species that is best adapted for the region you are growing the grass.
