A properly cared for lawn provides many benefits for homeowners. Lawns keep the soil surface cool, reducing the need for air conditioning. They offer a safe place for children to play and prevent soil erosion and water run-off. Lawns can even increase property value. Lawns need weekly care during the summer, though, to stay healthy. Establish a schedule for watering, mowing and fertilizing and you'll have a lush, green lawn in no time.
Set your lawnmower at a mowing height of 3 inches or higher. Leaving your lawn tall helps grass develop strong roots, conserves moisture and discourages weed growth. Mow your lawn when it is 4 1/2 inches high. Mow more in the spring when grass grows rapidly and less in late summer and fall.
Leave the clippings on the lawn when you mow. Use a mulcher attachment if your lawn mower has one to finely cut the grass. Grass clippings break down, providing valuable nitrogen for your lawn. Leaving the grass clippings means less work for you and less waste in the landfill.
Fertilize your lawn with a nitrogen-rich fertilizer in early August to October instead of spring. According to Cornell University Department of Horticulture, applying fertilizer in spring causes grass to produce top growth instead of strong roots. Spread fertilizer in a spreader according to package directions.
Water your grass one or two times per week, depending on the amount of rain you get. Grass needs 1 inch of water every week, so if you get frequent rainfall, you might not need to irrigate. Water in the morning for 45 minutes to one hour. Watering deeply, but infrequently, encourages strong root growth.
Consult a local county extension office before treating your lawn for disease or insects. Properly identifying the problem will save you time and money.
