We also provide core aeration and overseeding services, generally in September and October. These are included with our lawn care program and we recommend doing them on an annual basis since our clay soil becomes very compacted during the year. Core aeration pokes holes in the soil to loosen it, which is why we pair it with overseeding so that the grass seeds can sink further into the dirt and establish stronger roots. If you need dethatching, we also remove thatch buildup at this time.
