So, What Is Aeration Of Lawn?

Like mowing, fertilizing and watering, aeration is a lawn care practice. Aeration creates openings in the underlying soil structure. As a result, essential water, air and nutrients can penetrate to the roots of the grass. The process is also referred to “core aeration”. It’s a very useful process in the development of broader roots of the grass that produces a stronger and vigorous lawn.

Usually, you can complete the process with a motorized lawn detaching machine or hand tools.

Best Time For Lawn Aeration-Fall, Spring or Autumn?

The best time for aeration depends on three conditions:

It’s true that you can aerate your lawn at any time of the year. However, the best recommended time is just before or during periods of high growth, so that you have your yard aerated for peak benefits. But you should avoid during periods of stress to the lawn or immediately preceding, whether from drought or heat.

     Type Of Grass In Your Yard

  • The best aeration time for warm-season grass such as Zoysia, Centipede, Buffalograss, St. Augustine, Bermuda is between late Spring and early autumn, i.e. in May and June.
  • The best aeration time for cool-season grass such as fescues, Rye-grass, Bluegrass is in early spring or fall.

It’s better to aerate your yard at least one time per year. However, in the dry areas, it requires doing twice a year.

Before aerating in the spring, wait until you mow the yard. It’ll ensure the fast growth of the turf that will take advantage of the hole and air exchange at the root.


  • The Moisture Level Of The Soil

The moisture level of the soil of your yard can affect the quality of aerating it. The yard needs to be moist for the tines to penetrate into the ground. So, it’s wise to wait until a good rainfall. You can also water about a half inch of water to the yard before aerating.

  • Types Of Soil Your Yard Posses

Aeration Varies With Soil. Depending on soil type, your lawn may require more frequent aeration.

Clay soil– If your lawn has clay soil, aerate it at least once a year.

Sandy lawn– Sandy lawn needs to aerate once a year, or you may tackle the chore in alter years.

Also, if you use your yard for parking car, you should aerate it annually. If you live in an arid climate, aerate your lawn twice a year.

Tips For The Lawn Aeration

  • After aerating continue the basic lawn care practices, such as mowing, fertilizing.
  • After aeration, watering the yard is a good idea.
  • Avoid aeration when the turf is very wet or saturated, or the dirt contains enough moisture to be muddy.
  • Applying weed killer shortly after the following aeration is beneficial. But if you plan to overseed the subsequent aeration, you should skip the weed killer.
  • Overseeding following aeration is beneficial as it increases the seed-to-soil contact.
  • Try to control weeds before aerating as aeration process can help the weed seed to spread.
  • If you have a newly planted yard, wait for at least one year.
  • Avoid aerating during high heat or drought. Aeration in these conditions will stress the yard by allowing heat to dry soil.

Why Is Aeration Essential For Lawn?

Due to heavy foot traffic, your lawn soil may get compacted. Compacted soil and too thick thatch layer in the yard prevent the proper circulation of nutrients, water, and air.

  • Aeration is the antidote to compacted soil. The process breaks up the compacted soil and removes thatch.
  • The root system becomes stronger and grows into the holes left behind from aeration.
  • Your lawn can breathe a little better, and it’ll need less maintenance.
  • Aeration improves air circulation, nutrient absorption and water drainage to the roots.
  • Aeration helps decrease the buildup of thatch.

How will You Determine Your Lawn NeedsAeration?

How will you determine that your lawn needs to be aerated?

Well, there are two straightforward observations.

First, pull at least 3-inch core samples from your lawn to check compaction layers and thatch depth. If you find a thatch layer of more than ½-inch, you need to aerate your yard.

Second, observe the weed growth. Certain weeds such as prostrate knotweed, bluegrass or goosegrass often inhabit the compacted soil. So, the growth of these weeds is an indicator of compacted soil.

Third, observe the watering. If water is standing in specific areas where it didn’t before, it’s due to the compacted soil keeping water from penetrating through the soil.


Undoubtedly, aerating is a beneficial practice to achieve an appealing yard. Proper aeration lets your yard breathe again easily and bring it back to life.

Aeration helps to strengthen the root system that leads to healthier and thicker turf. Also, the grass can absorb more natural materials that benefit the soil to provide organic nutrients. It also makes your yard more resistant to high temperatures, and substantially it helps you to save water bills as you won’t need to water your lawn as often.
