Aerating is the process of mechanically removing cores of soil and grass to relieve compacted soil by improving the exchange of water and critical nutrients between the atmosphere and the grass roots.  Soil compaction is a frequent cause of lawn deterioration caused by lawn traffic such as walking, pets and mowing.  Compaction is greatest in the top 2”-3” of soil. Soil Compaction can have an adverse effect on the health of the lawn.  Compact soil prevents the grass from establishing a healthy root system.  Adequate amounts of vital lawn nutrients including water oxygen, nitrates, phosphorus, and potassium are unable to reach the roots.  Aeration relieves soil compaction by removing evenly-spaced plugs of soil up to 3” in depth depending on the condition of the lawn.
In drier climates like Colorado and especially in areas with bad soil, as is found in much of south Denver, aeration increases drought resistance while decreasing the amount of water required to keep the lawn healthy, green and lush.  For optimal effectiveness, we recommend aeration be done both spring and fall.  Since the cost for aeration is often recovered in just a month or two from the amount of water saved, many customers are now options for a mid-summer aeration as well.


  • Water your lawn thoroughly the night prior to the scheduled date of service; if possible try to water extra for several days prior to soften the ground.  Don’t soak the lawn because if it is too muddy it will not pull a good plug.
  • Mark sprinkler heads – particularly those not within the first 2-3″ of a perimeter. Use flags, sticks, plastic silverware, medium size rocks or even a spot of bright spray paint and wé will see them. ALSO: Please mark any invisible dog fence, wires, drains, or cables less than 3″deep so we can avoid hitting them

Note: Please clear your lawn of children’s toys and do not use them to mark your heads as we assume they were mistakenly left in the yard in play.

  • If you have pets it would be greatly appreciated if you would clean up after your pet prior to our arrival.
  • If you are also getting power raking at the same time we will do the aerating first and break up the plugs when we do the power raking. If you prefer to have the plugs left on the lawn please let us know when requesting service.

Note: In our many years of experience, we have not seen a noticeable difference between lawns if plugs are left or raked up. It is your personal preference, however, most clients prefer to have the aerating done first to chop up the aerating plugs and have them cleaned up to avoid a potential muddy mess of the plugs if you have children or pet in the lawn.

  • If we will only be aerating the lawn, it is recommended to leave the plugs. This is, after all, some of your best top soil. If you would like to have the plugs raked up, there will be an additional charge.
  • If you are also having power raking done at the same time as the aerating we do recommend that you water extra up to the evening prior to the day we are scheduled to arrive. DO NOT soak your lawn. Moisture will help the aerating to be more effective but excessive moisture at the surface makes the power raking more difficult.
  • If you are scheduled for a two-day block as we commonly do, and we do not get to your lawn by sundown the first day, you may water that evening if you get a chance.
