Across the northeastern U.S. and eastern Canada, cool season lawn grasses perform best. Bluegrass, often called “Kentucky bluegrass”, grows in zones with cool summer night temperatures and adequate annual rainfall. Bluegrass is not as heat and drought tolerant and a higher water use rate than tall fescue and warm-season grasses. Bluegrass performs best in moist […]
