A healthy green lawn brings life and vitality to a home. It makes your home and yard look clean and regal. A pristine lawn can even increase your property value. But maintaining a lawn to ensure it stays emerald green and glorious takes some work and regular maintenance. There is regular mowing and landscaping, fertilizing, and even aeration. Aeration is something not everyone does on a regular basis, but it’s very important. It is critical you notice the signs that it is time to aerate your lawn.

It is time to aerate your lawn when you notice peculiar puddles on your lawn, thinning grass or even notice your lawn is turning brown. Other signs that it is time to aerate your lawn include water absorption issues and noticeably compact soil. Heavily trafficked areas require more attention. Lawns should be aerated at least once a year, so if it has been longer than this, then consider aerating it.

Everyone knows they need to mow their lawn. Most homeowners with lawns have a seasonal nutrient, weed, and pest control routine to ensure the lawn stays uniform and green. But aeration, while sometimes tedious, is just as important to ensure new growth, health and longevity for your grass. Make sure you read further to know when you should aerate, and what the signs are that you should aerate the lawn right away.

How Often Should I Aerate My Lawn?

As a general rule of thumb, you should aim to aerate your grass every year. There are, of course, some variables to consider when you set up a lawn aeration schedule. The point of aeration is to free up the soil and allow for new growth so that grass does not start competing with itself and struggle to find soft soil to root in.

For sandy, lighter soils, you can often wait longer, sometimes upwards of two years, before you need to aerate your soil. But for those who have more hard soil types, you should never wait longer than a year. This is especially true for those who have clay soil, which is notoriously hard. If your soil is frequently trafficked, or parked on with a vehicle, consider aerating it every six months.

10 Signs That It Is Time To Aerate Your Lawn

1. Puddles On The Lawn

One tell-tale sign that it is time to aerate your soil is when you start to notice puddles on your lawn in places they did not exist before. The puddles you should look for aren’t the ones you notice after a flash flood or tons of rain. Instead, when you notice puddles after minimal rain, or simply after watering your lawn, then it might be time to aerate the soil. This is a sign that the lawn has grown too thick and needs to be broken up a bit to allow water in. After all, without water, you will see a major decline in the lawn’s appearance.

2. Your Green Grass Is Thinning Out

Another sign that it is time to aerate your lawn is if the grass starts looking thinner. If you are used to a nice soft bed of grass, but instead find yourself walking on a more sparse, hard or spongy surface, this is not a good sign. Aerating the soil will inspire new growth and a thicker lawn.

3. The Lawn Grows Unevenly

A patchy and uneven lawn is often a sign that the lawn, or at least parts of it, need aeration. If you notice your lawn growing unevenly, it could be due to the compact soil underneath or grass that needs room to breathe. This is particularly true if you have not noticed uneven growth in the past.

4. The Lawn Is Turning Brown

If you water your lawn regularly but notice it is turning brown, the sun and water might not be to blame. It might simply need room to grow. A lawn that slowly turns from green to brown, and is not water or sun-deprived, is often in need of aeration. Make sure you address this right away, as the longer you wait, the harder it is to quickly re-vitalize the lawn.

5. Trees Surrounded By The Lawn Are Struggling

Trees tell us all sorts of things. They can tell you when the soil is dry, when the air quality is poor, when the weather is warming up, and even when the lawn needs aeration. If you have trees (particularly younger more sensitive trees) surrounding your lawn, pay attention to them.

If you notice the trees are struggling more than normal for no particular reason, then you might need to aerate the soil. Trees will show these signs of struggle because non-aerated lawns might fail to provide the trees with the nutrients and water they need, since there is a barrier between the roots and the water.

6. You Notice A Layer Of Thatch On The Lawn

After mowing your lawn, and over time, there is bound to be a bit of dead grass buildup within your lawn. But when that buildup becomes a growing layer of the lawn, this is called thatch. If the thatch builds to a noticeable level — anything more than half an inch — it is sign that your lawn needs some aeration. Without aeration, this thatch can act as a barrier, blocking the lawn from getting essential nutrients like water and oxygen.

7. Parts Of Your Lawn Are Heavily Trafficked

We have all seen how terrible heavily trafficked lawns can get. What was once pristine seems to form its own compact trail. Heavily trafficked areas are sometimes difficult to avoid. But they are easy to treat. Try aerating these trafficked areas every six months or so. This will help combat the compact soil and promote growth.

8. Water Absorption Issues

In addition to puddles, you might notice other signs that your lawn is not absorbing water like it normally does. Lots of rain runoff onto sidewalks or down hills is one example. Noticing dry grass after frequent watering is another. Regardless, make sure you aerate the lawn when you notice this to prevent potentially major grass damage.

9. You Notice Your Soil Is Compacted

If you test your soil and notice it is harder than usual, then it might be time to aerate. This might occur when you try to dig into your lawn with a shovel and find it almost impossible to do so. This is a classic warning that your lawn needs aeration.

If your clay soil is particularly rock hard, or your soil sandy soil feels rock hard, then address the issue sooner rather than later.

10. It Has Been More Than One Year Since You Aerated Your Lawn

In general, you should aerate your lawn annually. If you have shady or nice crumbly soil, you can wait upwards of two years. Regardless, establish a healthy schedule. If you have gone past that self-imposed deadline, then aerate the soil to avoid these other negative visual signs.

Final Thoughts On Signs It Is Time To Aerate A Lawn

Aerating your lawn is an important part of lawn maintenance. You should aim to aerate your lawn once a year or so. If you do not stick to a schedule, you should at least look out for all the signs it is time to aerate the lawn.

These signs include random puddles of water where puddles normally don’t form, thinning grass, or even grass turning brown.

If you notice a layer of dead grass (thatch) that is more than half an inch thick, or your soil is noticeably compact, then you should act quickly to aerate the lawn.
