Aeration is an important part of any good lawn care program. It strengthens your turf against drought and helps protect it from pests, diseases and weeds. Aeration pulls “plugs” of soil, thatch and grass about 2-3 inches long from your lawn. This process opens the soil and creates thousands of tiny growth zones that attract the roots of your lawn. It’s the best way to get water, fertilizer and oxygen into the root zone of your lawn.
