Benefits of Core Aeration

  • Loosens compacted soil and increases the availability of water and nutrients.

  • Enhances oxygen levels in the soil, which stimulates root growth and enhances the activity of thatch-decomposing organisms.

  • While removing cores of soil, the spoons or tines also sever roots, rhizomes and stolons. Grass plants are stimulated to produce new shoots and roots that "fill up" the holes in the lawn and increase the density of the turf.

  • Reduces water runoff, increases water infiltration and percolation, and improves drainage.

  • Increases the lawn's drought tolerance due to enhanced root growth and improves its overall health.

Why is Aeration Necessary? 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.
