Bluegrass remains the same in popularity much as it was when first introduced to North American by early Europeans. Beautiful, lush and finely textured, this is the lawn grass most people strive for. BlueGrass is a Rhizomatous type of grass.Meaning that it spreads though the development of Rhizomes( underground stems) and can be fairly easily established from seed or sod. Seeded lawns establishment depends upon a well prepared seedbed, application of a starter fertilizer, following seeding guidelines with consistent watering schedules while the seedlings develop and thereafter as needed.  Due to the slower growth of Bluegrass, full establishment takes time (1-2 months is not unusual).  This is one of the primary reasons to include Perennial Ryegrass in a Bluegrass lawn.

PERENNIAL RYEGRASS LAWNS are one of the best lower maintenance lawns of the cool season grasses. and most wearable turf Ryegrass is known its quick germination, shiny green color,  fine texture and dense forming sod. High disease and insect resistance helps to make perennial ryegrass one of the best choices for lawn and athletic covers in the U.S.Perennial Rye Grass is also mixed with other cool season grasses to provide more density to the dominate grass in the mixture.  Perennial ryegrass is often added to Kentucky bluegrass to add strength and give bluegrass time to repair while the perennial is in full growth. These two grass species can be mown at the same height and retain a sod density for which both are well known.

The Fescues: The fescues are cool season grasses that are adapted to the transition zone and into Canada.  The fescue species are easily seeded and include the sub species of  fine shorter fescues named creeping red, hard, and chewing’s. Strong Creeper and Slender Creeping Red fescue are the few rhizomatous fescues with most being of the bunch type grass. This will mean a heavier seeding rate for the bunch type in order to achieve a uniform appearance. All of the fescues share the same variety characteristics with the three dominant ones being shade tolerance, staying green all year, and having very good drought resistance.

BENT GRASS: Creeping bent grass is a native of Europe and parts of Asia. It is a cool season grass requiring cool, humid environments. This grass forms a dense mat by creeping stolons and has a shallow root system and has long slender leaves
Bent grasses are the most beautiful of the grasses with their fine texture, deep green color, thick density, and low growing habit. They are considered the luxury grasses of the cool season grasses. Bent can be planted from seeds or sod and provides a beautiful golf like turf grass lawn in Northern areas.  Bents requires high amounts of lawn care & maintenance.
