The Best Grass

Before we start if you think you can grow grass try GROWING A VEGETABLE GARDEN

Kentucky bluegrass is the basic grass species for northern lawns. Many older lawns were planted with common Kentucky bluegrass some years ago. In the last few years, there has been a breakthrough in the breeding and development of the new improved bluegrasses.

The new named bluegrass varieties found in premium blends and mixtures have been developed with more heat and drought tolerance, and with greater insect and disease resistance. This makes the turf more persistent in crowding out weeds throughout the year. In seed mixtures, Kentucky bluegrass should be the dominant type grass seed.

Perennial Ryegrass

The new turf type perennial ryegrasses are the most versatile of the lawngrasses. They germinate rapidly and are often used in mixtures with the improved Kentucky bluegrasses. Perennial ryegrass germinates faster then Kentucky bluegrasses, which helps to prevent soil erosion during lawn establishment. The other valuable quality is that perennial ryegrass normally has better wear tolerance than Kentucky bluegrass.

Fine Fescues

There are several grasses that are called fine fescue. The most widely used is creeping red fescue. Its shade and drought tolerance makes it a popular variety in northern seed mixtures. Chewings fescue also is a fine fescue with good drought tolerance and is frequently used in mixtures. Neither of these grasses are routinely seeded alone, but generally used with Kentucky bluegrass.

Tall Fescue

Tall fescue has traditionally been used in the transition zone and upper south, but the development of new turf-type tall fescues has made them compatible in the cool, humid regions as well. Tall fescues have good heat and drought tolerance.

These grasses have a large root system and tend to grow well with less irrigation during hot summer weather and dry spells. The new turf type tall fescues often are sold as blends of two of more named varieties. However, mixtures in combination with Kentucky bluegrass are becoming more common. visit Grass Now
