Although often labeled as a water and energy hog, lawns remain a significant part of the home landscape. By establishing small, practical areas planted with turf species that require less water and implementing simple maintenance practices, you can have a nice lawn and also be environmentally responsible.

Amazingly, the inevitable, unwanted brown spots that appear in our lawns are seldom the result of insects. More often improper lawn care, ill-timed watering or a grass variety not suited to your yard are the causes of unhealthy areas. Many problems can be eliminated by performing routine maintenance on sprinkler heads, evaluating mowing practices and using care when applying fertilizers.

In order for a lawn to thrive, it must have a strong, vigorous root system. Lack-luster root growth can often be traced back to an irrigation issue or compacted soil. Contact your water agency to schedule a free irrigation system evaluation. When water puddles or runs off without soaking in, increase water movement down to the roots by aerating during the cool spring months.

At each mowing, cut only 1/3 of grass height and keep the mower blades sharp. Mowing too low removes too much of the food producing area. As the grass literally starves, the lawn thins and looks poor. Incorporate grasscycling; the natural recycling of grass by leaving clippings on the lawn. The clippings decompose quickly and release valuable nutrients back into the soil, reducing your fertilizer requirements. This simple practice will also eliminate a large amount of green waste from going to our landfills.

If feeding is necessary, use a slow-release fertilizer when grass is actively growing and apply no more than the recommended rates. Too much or improperly applied fertilizer can injure lawns and may contribute to water pollution through runoff. If excess nitrogen is applied too frequently, shoots will continue to grow yet root growth will slow, leaving the turf vulnerable to insects and disease.

Save your money by holding off on applying insecticides and herbicides. Prior to treatment, utilize non-toxic management methods and verify that a damaging level of an identified insect is the problem. A vigorously growing lawn will crowd out most weeds; consider tolerating the few that do appear.

No two lawns are exactly alike. Lawns may differ by turf species, soil type, climate, location, how they are used and how they are maintained.
