There are two types of lawn aeration machines: spike aerators and core aerators. Spike aerators simply punch holes in the ground using spikes, while core aerators use hollow tines that pull plugs, or cores, of compacted soil up from the ground. The professionals at Yardworx Outdoor Services will use a core aerator to remove plugs of soil 2-3 inches long from the ground every three inches or so. These holes will allow water and nutrients to reach the roots further down. The machine is run over the entire area, using multiple passes if necessary to ensure that the entire yard benefits from this service. This process works best when the ground is moist, but not wet or muddy. The plugs of soil will break down in a few weeks and filter back down into your lawn. A light raking or pass with a lawnmower will help to break up these plugs and ensure a more even redistribution.
After core aeration, it is important to continue regularly scheduled maintenance such as mowing, watering, and fertilizing to keep your yard looking its best. It is also recommended that you overseed or fertilize your lawn after core aeration as the opening in the ground provides deeper access for the seeds and fertilizer.
