Or maybe you noticed the ground was really hard and you Googled the term, only to find that lawn aeration usually solves that problem. That's all well and good, but just what is a lawn aeration service, and how can it help your lawn?

What is lawn aeration anyway?

Just like your body, your lawn needs a way to “breathe” in oxygen, to open up and receive nutrients and adequate hydration. Aeration is one of the best ways to make your lawn thicker and improve the effectiveness of normal irrigation and fertilization. Lawn aeration is designed to remove small plugs of turf, thatch and soil from your lawn. These plugs break down and feed nutrients back to your lawn's root system.

Using a machine called a lawn aerator creates “pores” in the ground, between one-half and three-quarters inches in diameter, loosening the hardened earth and allowing nutrients and fertilizer to move around. The cores that are pulled out of the ground with the lawn aerator are placed on the soil surface, to be broken up by irrigation, mowing or rainfall.

How can lawn aeration help your lawn?

Lawn aeration services, at the correct time of year, provide numerous benefits:

  • Improves Turf Health. Core lawn aeration provides the root zone with greater access to air, water, and fertilizer. This access to air, water, and nutrients, improves the overall health of the turf. Also, turfgrass roots will be deeper and more extensive.
  • Aids Thatch Management. Core lawn aeration helps in thatch management by punching holes in the thatch layer, and by introducing thatch-decomposing microorganisms from the soil to the top of the thatch layer.
  • Relieves Soil Compaction. Removing cores relieves compaction and decreases soil density.
  • Benefits pH Modification. Applying lime or sulphur after lawn aeration promotes the change of pH deeper into the soil profile. This will let nutrients penetrate deeper in the root zone to become available to the turf.
  • Benefits Overseeding Operations. It is helpful to core aerate before and after seeding into an existing lawn. Soil cultivation enhances seed-to-soil contact necessary for germination, and creates a moist, protected environment optimal for seedling growth and development.
  • Lawn aeration is a service that does not need to be done frequently—once a year for a healthy lawn or twice a year if your soil is compacted. It is, however, a process best left to experts. TruGreen® offers lawn aeration service as well as many other lawn care services and plans. Visit or call 866.688.6722 today to learn more about lawn aeration services.
