Mowing Practices

Table of Contents


Lawn mowing is more time consuming than many of the other cultural practices involved in caring for a lawn. Regular mowing with a sharp mower blade at the proper height will help keep grass growing vigorously and maintain adequate density to completely cover the soil surface.

In addition, mowing with sharp blades will cut the grass blades cleanly rather than tearing and shredding (Fig.8.1) them as would be the case with dull blades. This will cut down on the amount of water lost from the grass plant thereby conserving moisture and reducing the need for additional watering. Shredded ends of the grass blade are more susceptible to disease invasion and can increase the need for fungicides.
