Warm-season grasses perform best in southern climates where summers are
hot and dry or humid and winters are mild. During the winter, warm-season grasses may go dormant and lose their green color if the average air or
soil temperature drops below 50 - 55 F. Some warm-season turfgrasses will
die if exposed to extended periods of subfreezing temperatures.
Cool-season grasses do best in northern and coastal climates where summers
are mild and winters are cold. Cool-season grasses thrive during the fall
and early spring. They remain green year-round unless temperatures consistently
fall below freezing.
Some warm-season grasses may tolerate colder climates better than others.
Likewise, some cool-season grasses tolerate warmer temperatures better
than others do. When planting, choose a variety that best suits your conditions.
