Cool-Season Grass Types: Bluegrass, Fescue, Ryegrass, and Bentgrass

Identify and care for Kentucky Bluegrass, Perennial Ryegrass, Tall Fescue, Fine Fescues, and Bentgrass across USA, Canada, and the UK. Optimal mowing heights, watering needs, and shade tolerance.

Cool-season lawns in the northern USA, Canada, and the UK are built on Kentucky Bluegrass, Turf-Type Tall Fescue, Perennial Ryegrass, Fine Fescues, and, on specialized turf, Bentgrass. Each species has a different mowing height, shade tolerance, and water need.

Kentucky Bluegrass spreads by rhizomes and recovers from wear. Tall Fescue has a deeper root system and better summer heat tolerance. Perennial Ryegrass germinates quickly for overseeding. Fine fescues handle shade and low fertility. Match the seed to your soil and light, then mow at the height that species can actually sustain.
