Lawn care is a rather labor intensive process during the summer months, when the grass is actively growing. To keep the grass green and lush, there are several cultivation practices that need to be followed, including mowing, fertilization, aeration and weed control. Natural grass care will prevent the growth of weeds and keep the lawn dense and healthy throughout the summer.
Take a sample of soil from your lawn and perform a pH test on it using a store bought pH test and following the instructions on the label. Apply minerals to the lawn to balance the pH in the fall or spring according to the results of the test. If doing your own pH test makes you nervous, send a sample of your lawn soil to your local university extension, who will send you recommendations on how to balance your soil.
Measure the size of your lawn to determine how many square feet the yard is. The University of Missouri suggests measuring the yard in rectangles. Take the the width times length of a rectangle to get a sum of the total area, and add all the different sections of your yard together. This will determine how many square feet of lawn you have and how much fertilizer to apply.
Apply dry fertilizer to the lawn at a rate of 1 lb. fertilizer per 1000 square feet of lawn says the Ohio State University Extension. A nitrogen-heavy fertilizer is best, with a 3-1-2, 4-1-2 or 5-1-2 ratio.
Mow the lawn once it has reached a height of over 2 1/2 to 3 inches, suggests Colorado State University. Adjust the height of your lawn mower so that it cuts only 1/3 of the grass blade at a time, to prevent stress to the lawn.
Aerate the lawn using a core aerator to remove thatch, which is dead plant material, and to increase moisture absorption and air circulation in the lawn. Aeration devices remove plugs of soil from the lawn, which break down on top of the lawn thatch, decomposing the material. Ohio State University Extension suggests aerating in the spring or fall.
