If your lawn is suddenly showing brown spots after a few days of warm weather or water pools after watering or a storm, you may need to supplement your supply of lawn care tools with a lawn aerator.
When thatch builds up under the grass and soil becomes compacted, water can’t penetrate to the roots, keeping the roots from growing long enough to resist high heat and temporary drought. Under these conditions, mowing, edging, and watering your grass are not enough to keep your lawn healthy. Keep reading to learn how lawn aerators work and how to determine when lawn aeration is necessary.
If you think this is one DIY job better left to the professionals, TruGreen has the experience and know-how to aerate your lawn and complement the aeration with a full line of lawn care services, including:

Lawn aerators use rows of spikes or hollow tines to penetrate the soil, cutting through thatch and breaking up compacted soil to allow air, water, and other nutrients to reach the roots of your grass. Aerating your lawn promotes the decomposition of organic matter, helping to fertilize the grass.
Aeration also encourages deeper and stronger roots, making your lawn more resistant to heat, drought, and insects. Using a lawn aerator can help your grass grow thicker, greener, and more robust.
A few simple tests can help you decide if your lawn needs to be aerated.
The simplest way to determine if your lawn needs aeration is the screwdriver test. Simply push a screwdriver into the soil of your lawn. If the soil doesn’t give easily, it’s too compact to sustain a healthy lawn. Aerating your lawn can fix that.
Dig up a small patch of grass about six inches deep. If the roots are shorter than two inches, your lawn could benefit from aeration.
During a Healthy Lawn Analysis, your lawn care specialist from TruGreen can determine if your lawn needs to be aerated and when would be the best time to do it.
Thatch is a buildup of dead grass and other organic debris that collects on top of the soil. A thatch layer that is thicker than a half inch can choke your lawn of air and nutrients.
Simpler than raking the thatch manually, aerating your lawn will break up the thatch and allow your grass to breathe, hydrate, and ultimately grow stronger.
The best time to aerate your lawn is during the growing season for your grass—either in the spring or early fall. Soil is typically moist during this time because of rainfall, and the aerator is able to pull enough core plugs.
Not all grasses grow at the same time during the year. Cool-season grasses such as fescue, bluegrass, and ryegrass should be aerated anytime from August through October. Allow at least a month of growing time before the threat of frost—for example, if frost sets in around the beginning of November, you’ll want to properly aerate your cool season grass by the end of September.
Warm-season grasses like Zoysia, Bermuda, and St. Augustine should be aerated in the spring from April through June. After you aerate your lawn, apply a top dressing to add organic matter into the soil that will help nourish your grass.
Aeration can be done in the summer as long as the soil is moist enough.
There are two main types of rolling lawn aerators: spike aerators and core aerators.
As the name suggests, a spike aerator uses spikes fixed on a rolling drum to poke holes in the soil as the aerator is pushed or towed across the lawn. Used to prepare soil for overseeding, spike aeration works best on soil that is only loosely compacted.
A core aerator uses hollowed-out tines to pull out plugs of soil from the lawn, leaving two- to three-inch holes. Both types can be motorized, manually pushed, or towed.
If a motorized lawn aerator is too elaborate for your needs—maybe your yard is small or you just want to aerate the trouble spots—here are five other aeration techniques that can be used for smaller jobs and make this DIY task as easy as a stroll through your yard.
This is the easiest way to aerate your lawn. Simply strap on these spiked soles and take a walk through your grass.
However, spiked shoes should not be used for every aeration job. Severely compacted lawns will not benefit as much from spike aeration as much as core aeration because the spikes actually further compact the soil they penetrate.
While not practical for very large yards and less effective on severely compacted lawns, this lawn aeration tool can be an inexpensive way to maintain proper soil conditions.
You can easily aerate small areas of your lawn by simply pushing a pitchfork into the soil about three inches deep. Wiggle the fork around a bit to widen the holes, and repeat the process every four inches over trouble spots. Caution: a pitchfork works much the same way as spiked shoes and should not be used for severely compacted yards.
Also called a dethatcher, this tool works mainly to break up deposits of grass cuttings, moss, and other debris that collect on the surface of the soil.
Powered by electricity or manually pushed, a scarifier is a wheeled machine with a series of blades that rotate through the surface of the lawn as it passes over it. Its cutting action also helps aerate the soil.
This tool, sometimes called a core aerator, works the same way as a pitchfork but uses hollow tines to remove cores of soil.
Using a series of blades to penetrate the soil, a slitter cuts through grass roots, encouraging air circulation and new growth.
You can purchase or rent a home aerator at a home improvement store or garden center relatively inexpensively.
You might be wondering how a single aeration every year could help improve your lawn’s quality. Think of a lawn aerator as a way to create pores for your lawn. These “pores” need to be made and left open in order for your lawn take in nutrients and moisture. They also promote root growth in the open spaces and added air and oxygen in the soil.
Homeowners with lawn care experience may find this job takes less time than newbies. You may need to prepare to commit your weekend to this project.
If you aerate your lawn regularly, you may not need follow-up care, which will save you time between each aeration.
If your lawn does need follow-up care, you will need to consider the weather conditions. Heavy rain after overseeding can wash the seeds away, requiring another application.
Lawn care can be miserable if it’s too hot, humid, or rainy. Will you be ready to work in the yard when the weather allows?
Bone-dry soil is difficult to aerate. You want the soil to be moist, but not muddy. If you have drought conditions, water your lawn lightly for a few days before you aerate.
Outdoor DIY jobs require several conditions to be optimal before you can proceed. When the weather is right, will you have the time, money, and energy to complete the job?
Will you be able to be aerate your lawn as often as it needs? If not, finding someone who will be available (like a professional) may be key.
