Aerating Your Lawn

An aerator creates air in your soil so your lawn can "breathe," allowing it to better absorb water and fertilizer. If you have standing water on your lawn or your fertilizer doesn't seem to be working, you may need to aerate. Aerators can be purchased or rented, and there are two types: manual aerators, consisting of a handle on a T-bar with four hollow pipes that are plunged into the lawn to remove cores of soil; and mechanical core aerators. KSU recommends Kansas residents aerate their lawns approximately twice a year.


Determine the type of fertilizer you need by having your soil tested. Fertilizer comes in liquid and granular forms; determine which type is best for your lawn. Grass should be fertilized when it is actively growing, so fertilize in fall and spring for cool-season grasses and in late spring and summer for warm-season grasses. Application methods and frequency will depend on your soil type. Click here for more detailed information from KSU.


Though herbicides, insecticides and fungicides can be effective in protecting your lawn and plants, they can have adverse health and/or environmental effects. Overapplication can lead to the pesticide draining into our water supply and killing other, helpful organisms. KSU recommends using pesticides sparingly and employing other methods, such as Integrated Pest Management (IPM), to control pests.

Mowing height is very important to the health of your lawn. Proper mowing height varies on the species of grass. For frequency, use the one-third rule - never mow more than one-third of your lawn's height at one time. Therefore, your mowing frequency will vary based on weather and other conditions affecting grass growth. Establish several different mowing patterns with as few turns as possible to reduce wear and tear on the corners of your lawn. Click here for more tips.


Yard waste accounts for about 10 percent of a household's annual landfill contribution. The best way to get rid of grass clippings is to leave them where they fall; if you follow the one-third rule, they will not clutter the yard. You can also compost your clippings, use them as mulch or take them to a recycling center.


Overwatering your lawn can put a big strain on the environment. Frequency depends on weather, grass type, soil type, season, shade, grass height and slope. Deep and less frequent watering is preferred to shallow and frequent. Click here for more advice.
