Cool Season Grasses

Cool Season Grasses

Cool-Season grasses tend to grow best in the cooler conditions and climates, hence their name. You will commonly find cool-season grasses growing in the northern areas of the U.S. and Canada, as well as moderate coastal areas, damp climates, and higher elevations. Cool-Season grasses are the hardiest of grasses and tend to do best during the spring and fall months when temperatures range from 60-75 degrees F. Conversely, Cool-Season grasses tend to do poorly during the hot and dry summer months and can even brown and go dormant during extreme conditions.

The draw-backs to Cool-Season grasses are that they do not handle extreme summer conditions of heat and drought well and can become unsightly during these periods of time. However, with proper watering and/or irrigation, they can survive such periods with a little help. Cool-Season grasses can also be used to reseed Warm-Season grasses during the winter months when lawns tend to brown and go dormant.
