If you are putting in a new lawn, it will be worth your while to do some research to identify the best grass type for your needs. If you're working with an established lawn that fails to thrive despite proper care, you might consider replanting with a different type of grass. Grass that is well adapted to your area will grow better and resist local pests and diseases better. New grass varieties and mixtures come out on the market every year. Ask your county extension agent or another one of the sources listed in this brochure for recommendations.
Longer grass has more leaf surface to take in sunlight.
This enables it to grow thicker and develop a deeper root system, which in turn helps the grass survive drought, tolerate insect damage, and fend off diseases. Longer grass also shades the soil surface keeping it cooler, helping it retain moisture, and making it difficult for weeds to germinate and grow. The ruler at the back of this brochure will help the best mowing height for your grass variety. You may have to readjust your mower - most are set too low. It's also important to mow with sharp blades to prevent tearing and injuring the grass.
