AerationLawn aeration involves the removal of small soil plugs or cores out of the lawn. Quality Care provides aeration done with a machine that has hollow tines mounted on a drum. Known as a core aerator, it extracts 1/2 to 3/4 inch diameter cores of soil and deposits them on your lawn. Soil cores are best left on the lawn surface; they typically work back into the grass in 2-4 weeks.

Aeration holes are typically 1-6 inches deep and 2-6 inches apart. Aeration relieves soil compaction, improves water and nutrient movement in the soil, increases rooting, and prevents thatch accumulation. Aeration improves the growing conditions for the turfgrass plants and results in a healthier, more vigorous lawn. If your property has an irrigation system or invisible pet fence please contact us so that your technician can properly mark these utilities prior to service in order to avoid any possible damage.

As lawns age or sustain heavy use from play, sports activities, pets, vehicle traffic and parking, soil compaction can result. Soil compacting forces are most severe in poorly drained or wet sites. Compaction greatly reduces the pore space within the soil that would normally hold air.

Roots require oxygen to grow and absorb nutrients and water. Compaction reduces total pore space and the amount of air within the soil. It has a negative impact on nutrient uptake and water infiltration, in addition to being a physical barrier to root growth. This results in poor top growth and lawn deterioration. Core aeration can benefit your lawn by:

  • Increasing the activity of soil microorganisms that decompose thatch.
  • Increasing water, nutrient and oxygen movement into the soil.
  • Improving rooting.
  • Enhancing infiltration of rainfall or irrigation.
  • Helping prevent fertilizer and pesticide run-off from overly compacted areas.

The frequency of aeration is largely determined by the soil type and the amount of use. Lawns growing in heavy, clay soils and those subject to heavy foot or pet traffic should be aerated twice a year. Once a year should be sufficient for lawns that are established on well-drained soils and experience little traffic.

In Iowa, September and April are the best times to aerate Kentucky bluegrass and other cool-season lawns. While the overall results are beneficial, core aeration does cause some initial damage. Aerating in September or April allows the grass to quickly recover during the favorable growing conditions in early fall and spring. Lawns may be fertilized and seeded either before or quickly-following aeration.
