What Does Aerating a Lawn Do?

While admiring the lush nature of a neighbor’s lawn, it’s natural to inquire about what they do to keep the space in tip-top shape. One of the responses you’ll often hear is “I aerate my lawn.”

This may draw a correlation between lawn aeration and a healthy, thick lawn, but what it doesn’t tell you is exactly how this lawn care technique helps achieve these results. With this in mind, we wanted to answer the question for homeowners: What does aerating a lawn do?

The Art & Science of Lawn Aeration

While there are a few different methods that can be used to aerate a lawn — with core aeration being the optimal route — the approach is relatively the same: a machine perforates tiny holes into the soil, allowing air, nutrients and water to reach grass roots and help them grow deeply.

The need for lawn aeration is driven by compacted soil. Due to mechanical stresses like heavy traffic or regular mowing (among other factors), soil particles can be pushed closer together, which in turn decreases the density of the soil and limits its pore space. This ultimately leaves little room for water filtration and air movement within the soil, negatively affecting lawn health.

Best performed in spring or fall (or better yet, both seasons), lawn aeration essentially loosens the soil to restore the breathing room it requires. Newly opened spaces in the soil allow nutrients to reach grass roots — and as these roots become healthier, plants have the room they need to grow to their full potential.

(Tip: How do you know if your soil is compacted? While thin, patchy areas of grass can be a strong indicator, we also advise looking out for the pooling of water in low areas of your lawn as well as water runoff in high areas. When water fails to infiltrate soil, it can be a sign that soil particles are too close together.)

DIY Versus Professional: Which Way to Go With Lawn Aeration

As is the case with our lawn maintenance tasks, there’s often the debate over whether to take the DIY route or hire professionals to handle lawn aeration. Here are some of the reasons we recommend turning the reins over to a professional.

Reduced Costs

The cost of renting or buying an aerator for your lawn can add up quickly. (Aerator rentals can go up to $80 per day, while the average aerator can cost you double that price to purchase.) By hiring a professional, you’ll gain access to state-of-the-art aeration equipment without the cost of having to invest in (and in some cases, maintain) the machine.

Minimal Time

Let’s say you’re aerating a lawn that is about 5,000 square feet. If you performed that task on your own, that would translate into at least several hours of work — taking away time that could be spent relaxing with your family. Having a professional handle aeration gives you more time back in your day and also limits physical labor that can lead to fatigue and even injury.

Better Results

When lawn aeration isn’t performed correctly, it can actually cause more damage than good. A professional with years of experience can give you the assurance that your lawn’s needs will be met and that the best results will be achieved. Your lawn will look its best, and you’ll avoid costly repairs down the road.
