Lawn Core Aeration involves perforating the soil with small holes to allow air, water and nutrients to penetrate the grass roots. This helps the roots grow deeply and produce a stronger, more vigorous lawn. The ideal time to have your lawn aerated is during Spring and Fall, when the lawn is actively growing. Normally, aerating your lawn once each season is sufficient for good healthy turf. If you plan to fertilize and overseed your lawn, aeration is essential. Pricing starts at $60 per visit.
