WHY IS LAWN AERATION NECESSARY?
Compact soil prevents grass from establishing a healthy root system and keeps water and fertilizer from reaching the roots.
In most home lawns, fertile topsoil may have been removed or buried during excavation of the basement or footings, forcing grass to grow in subsoil that is more compact, higher in clay content and less likely to sustain a healthy lawn.
Walking, playing and mowing will compact soil and stress lawns. Raindrops and irrigation further compact the soil, reducing large air spaces where roots readily grow. Compaction is greater on heavy clay soils than on sandy soils, and it is greatest in the upper 1 to 1 1/2 inches of soil.
Aeration can help relieve soil compaction, allowing your grass to grow deeper roots and make better use of water and fertilizer making the landscape maintenance of your yard looking beautiful.
