TURFGRASS - OVERVIEW

Turfgrasses defined.

Turfgrasses are "fine-textured grass species that form a uniform, persistent population of plants and that tolerate traffic and low-mowing heights." This "persistent population" is more commonly referred to as "the lawn."

Benefits of a properly maintained lawn.

In addition to the obvious aesthetic appeal, a well maintained lawn provides the following benefits:

Cooling. On a hot summer day, grass can be ten degrees cooler than exposed soil and as much as 30 degrees cooler than concrete or asphalt.
Enhancement of air quality. Grasses create oxygen and absorb pollutants such as soot, dust and carbon monoxide.
Water quality. A healthy lawn acts as a sponge to absorb rainfall and return it to the watertable.
Soil retention. A healthy lawn prevents soil and water erosion, causes of topsoil depletion.
Design element. Grass provides a color and textural contrast to shubs, trees, planting beds and other landscaping features.
Exercise opportunity. Using a walk-behind mower to cut grass provides an opportunity for the operator to engage various muscle groups and to burn calories.
Sound absorbtion. A well maintained lawn reduces street and other noises.
Recreation area. A well maintained lawn provides a safe exercise and recreation area for humans and pets.
Increased property value. A well landscaped and maintained lawn may add approximately 7% to the value of a private residence.

Keys to a healthy lawn.

A healthy lawn does not just happen. It begins with soil preparation and selection of the proper turfgrass species. Thereafter, one must be aware of the season and practice proven management techniques at the appropriate times.
