Lawn Aerator Buyers Guide
Why do you need to aerate your lawn? That’s a common question from newbie gardeners. Your lawns soil experiences “compaction” over time. The soil compresses together due to heavy rainfalls, foot traffic, and various other reasons.
Eventually, the compaction gets so intense that it prevents air from penetrating the ground. Grass needs a consistent flow of fresh air to the roots to survive, just like any other plant. If the roots don’t get enough air, the grass starts to die back, resulting in thinner lawns with bare patches.
By aerating your lawn, you loosen the soil, allowing air to penetrate the soil’s surface and reach the roots of your grass. Aeration also provides water and nutrients to penetrate the ground, resulting in a boost of nutrition to your lawn that spurs growth.
Aerating Vs. Dethatching – What’s the Difference?
Any gardener that spends some time researching lawn aeration comes across the term “dethatching.” What is dethatching? Thatch refers to the dead grass stems, roots, and blades that fall into the soil. In essence, the thatch is the layer between the earth and your healthy grass.
Thatch is good for the health of your lawn. Most lawns thrive if they have a ½-inch layer of thatch under the surface layer of the grass.
The thatching is especially helpful if you live in USDA zones 8 to 11. These regions experience strong sunlight that causes extensive evaporation of water from the soil and might end up killing off your grass. The thatching helps to prevent the ground from getting too warm while retaining moisture.
However, more than ½-inch starts to give you lawn problems. The thatch cuts out sunlight and air from reaching the ground, accelerating the compaction process. Your grass might also root in the thatch, preventing it from getting access to the nutrients it needs to grow.
If your lawn has extensive thatching, then you’ll benefit from the use of a dethatching machine more than an aerator. However, using both tools is an excellent way to remediate your lawn. There are combination tools you can use that both dethatch and aerate your lawn for best results.
Is It Necessary to Aerate the Lawn?
While aeration and dethatching are excellent methods to increase airflow to the roots of your grass, some gardeners might not need to use this technique for adequate lawn management. Here are a few tips to check if your lawn qualifies for aeration.
If your lawn dries out quickly, especially in the strong sunlight, it might develop a springy feel underfoot. The spring sensation comes from a thick layer of thatch under your feet. To check the status of your lawn, chop out a chunk to a depth of 1-foot. If you find that there’s a layer of thatch that’s deeper than ½-inch thick, then you’ll need to consider dethatching and aerating your lawn.
If you live in new construction, then the chances are that the building activity compacted the soil in your lawn. Building contractors move back and from the site all day, building perimeter walls, patios, and the like. As a result of the foot traffic, the soil starts to compact. In this case, you’ll need to aerate the compacted soil to facilitate the growth of your grass.
If your kids and pets spend plenty of time playing on your grass, the soil might start to compact. Pets also tend to travel along the same paths around your property, creating “runs.” These runs slowly compact6 the earth over the year, resulting in spare areas where you can see a trail in your grass. Aeration of the trail improves airflow to the roots, allowing your lawn to recover.
If your lawn features construction with layers of sod on top of the soil, it might cause settling of the sod and compaction of the soil. The sod has a different density to the soil, resulting in separation of the layers and a reduction in airflow and water absorption into the ground. Aerating your lawn balances the sod and soil, enhancing the health and growth rate of your grass.
The Benefits of Aeration
So, why would you bother with aerating your lawn? Dethatching and aeration have many benefits for your grass.
Here are our top benefits for aerating your lawn this growing season.
- The soil loosens and absorbs more water from rainfall and watering practices.
- Aeration reduces compaction, allowing the roots of your grass to breathe and absorb nutrients.
- The thatching breaks down much easier, resulting in more water reaching the roots of your grass.
- Your lawn becomes more resistant to heat stress and drought conditions.
- The oxygen flow to the roots of your grass increases, spurring lawn growth.
- Your lawn gets robust root development.
- You decrease water run-off in your lawn significantly.
As you can see, it’s to your benefit to dethatch and aerate your lawn at least once a season. If you aerate your grass, it stimulates growth by increasing your lawn’s ability to breathe and absorb water and nutrients.
The Best Time to Aerate Your Lawn
When is it the best time to aerate your lawn? If you follow the lawn test outlined above and find that your grass is in desperate need of dethatching and aeration, then it’s time to take action. Experts recommend that you aerate when the growing season is well underway.
By aerating your lawn when your grass is growing fast, you mitigate the damage you do to the roots of the turf during dethatching and aeration. As a result, your lawn recovers from the stress of aeration quickly.
If you have a lawn with cool-season grasses, then it’s best to aerate during the early springtime. If your lawn has warm-weather grass, then aerate during the late spring for best results. Aerating too early in the season may damage the roots of your grass. As a result, it takes the lawn longer to recover, and you might end up with sparse patches.
The answer depends on your situation. If you have a decent lawn and are looking to maintain its current condition, then once a season in the springtime is more than sufficient. This strategy leaves your lawn looking lush and green all through the summer, and ensures your grass has robust root systems that survive the winter.
However, if your lawn is new or has severe compaction, you might need to aerate it more often to stimulate the growth of your grass. At the top end, aerating up to 5-times a season is preferable. Many golf courses aerate between 3 to 5 times a year, but that because they have plenty of foot traffic.
What Results Can You Expect from Aerating Your Lawn?
After finishing your first round of aeration, the plugs form deposits in a uniform formation of lines across your lawn. It looks like a squadron of trained moles decided to dive through the grass, leaving tiny little molehills behind.
This soil assimilates into the grass with each watering session and disappears entirely in a few days to a week. After 7 to 10-days, take a look inside the aeration plugs. You should notice white roots beginning to show in the base of the plugs. That’s a good sign that the aeration was a success, and your lawn is reaping the benefits.
You’ll also notice that the water retention of your lawn increases with each watering, and there’s less pooling after thunderstorms as well. As a result, the grass absorbs more water, turning thick and lush.
Spike Aerators Vs. Plug Aerators
You get two options for aeration tools – plug or spike aerators.
Spike aeration tools are usually manual tools that look similar to pitchforks. However, the “fork” has up to 6-prongs that are straight and thicker than a regular pitchfork prong. There’s also a strike-plate that stops the prongs penetrating the ground past the ideal depth. That’s a handy feature for avoiding hitting any buried wiring or pipes.
When you push a large-diameter spike into the ground, some gardeners argue that the actions increase soil compaction. The action can “seal” the area around the spike as it drives into the compacted soil.
These gardeners can benefit from a plug aerator to resolve this issue. A plug aerator drives a tube into the ground, removing a small soil sample. It takes this “cut-out” and deposits it on the surface after removal. As a result, your lawn has hundreds of plugs made by the machine, and you’ll notice tiny deposits spread uniformly across your lawn after you finish.
When choosing a plug aerator, you’ll want a machine that takes plugs to a depth of 3-inches deep and 0.5-inches wide. You need a distance of 3-inches between the plugs for optimal aeration of your lawn.
Steps to Aerating Your Lawn
Aerating your lawn isn’t a complicated process if you have the right tools. This quick step-by-step guide to aeration will walk you through everything you need to know.
Water the Previous Afternoon
The soil needs to be as moist as possible before you start. Water the lawn the afternoon before you aerate to give it enough time to absorb it and limit evaporation. Trying to pull the plugs out of dry soil is challenging, and requires more than double the effort of when the lawns moisture levels are high.
Let the Plugs Dry
After pulling your plugs, let them dry. Some gardeners make the mistake of raking them in straight away, and some of the soil ends up back in the plugs, defeating the purpose of the exercise.
The plugs dry and fade away by themselves in most cases. However, if they’re still there after a week, then you can rake them into the lawn.
Take a few Passes
Your lawn aerator doesn’t cover a large area. Therefore, you’ll need to run a few passes. Think of it as mowing your lawn twice. Use the same motion of moving back and forth over the entire surface, and then do it again for good measure.
What Factors Play a Role When Buying a Lawn Aerator?
The Size of Your Lawn
Those individuals with small lawns in cluster homes or small free-standing homes can get away with a manual aerator or a push unit. If you have a larger property, then you’ll need a tow-along aerator or a gas-powered model. Choose the right model to suit your garden and your needs.
Plugs or Spikes?
As mentioned, there’s some controversy over this issue. Spike aerators do provide some benefit, but we think a plug aerator is the best route to go if you have the budget. Manual plug aerators might also struggle to release the plug after pulling it from the lawn, requiring you to manually remove it, adding a significant amount of extra work into the task.
The Types of Aerators and Dethatchers
When choosing your aerator, you have three options. Aerators and dethatchers come in manual, tow-hitch, or push models. Select the model that’s the right choice for your garden.
Manual Aerators
Manual aerators require you to do the work. For instance, “fork-style” aerators need you to push into the ground using your foot. These types of aerators typically suit small yards that have ornamental lawns. Trying to use this aerator for a large yard will take hours of back-breaking work.
Tow-Hitch Aerators
If you own a large property or estate, and you already use a sit-down mower for your lawn, then a tow-along aerator is your top choice. Tow-along aerators hitch to any mower, ATV, or tractor. You’ll have to load the aerator to give it enough pressure to force the cutting spoons, twines, or knives into the soil.
Push Aerators
If you have a medium-size garden, and you use a mower on your lawn, then you can look at purchasing a push-along aerator. These systems come in electric and gas-powered models. However, we recommend you use an electric model. A gas-powered version is noisy, and it pollutes the local environment as well.
A Word on Warranties
When selecting your lawn aeration tool or machine, always look for at least a 3-year manufacturer’s warranty on the product. You’ll only be aerating your lawn a handful of times a year at most, so having an extended warranty on your machine is important to safeguard you against future problems.
Wrapping Up – The Verdict
Choosing the right aerator or dethatcher for your lawn depends on your situation. If you have a small ornamental garden in a cluster home, then we recommend the manual aerator. The Yard
Butler is both an affordable and durable tool that will last for years. We like the spiked shoes, they’re a good idea, but we don’t like the spike-style aeration technique.
If you own a home with a medium-size yard, then check out the Greenworks push aerator. This model is reasonably priced, and Greenworks make some of the best gardening tools and machines available. The electric operation is kind on the environment, and it effortlessly aerates your lawn.
For those gardeners that have to aerate large lawns on plots, estates, or entertainment grounds like golf clubs, then a tow-along aerator is your best option. These aerators hitch up to any ATV, mower, or tractor, and they offer the effortless aeration of your lawn.
If we had to choose, the Agri-Fab 40 is the best two model, and we think its sturdy design and wide cutting deck is ideal for any large lawn.
When making your final selection, ensure that you purchase the right lawn aerator for your yard. Use the information in this guide to help you reach an informed purchase decision on your new garden tool.
