Get the Inside Scoop on Lawn Aeration

If you want your lawn to look good, you will benefit from discovering a host of facts about lawn aeration. Today, we are here to help! We want you to use this lawn care process, which delivers vital nutrients to soil under grass. When you add aeration to your current lawn care tasks, including fertilizing, watering and mowing, you’ll be doing all that you can to create a truly beautiful and healthy lawn.

Aeration will allow nutrients to penetrate the soil and it will also allow water and air to get through lawn thatch or grass…

Now, we’d like to talk about when and how to aerate. We’ll also share more facts which help you to understand the value of lawn aeration.

Lawn Aeration – Basic Facts

Aeration is the act of perforating soil with holes of small size which allow nutrients, air, and water to get into the roots of grass. Aeration gives roots the power to grow deeper into the soil and to produce grass which is healthy and strong.

Aerating is usually performed in order to improve soil compaction issues. When a soil is compacted, it contains an excess of particles which are solid, within a particular area. Compaction of soil inhibits nutrient, air and water circulation with soil.

Too much lawn thatch or dense debris which is organic will lie under the surface of grass and it may “starve” roots from accessing the water, air, and nutrients that they need in order to grow well.

What Are the Benefits of Aerating Lawn?

If you’re a homeowner, you should strongly consider aerating your lawn. In particular, if you fit the following criteria, you should give it a try…

If your lawn gets a lot of traffic from kids who play on it and/or pets who run around on it, then lawn aeration should improve the condition of your lawn, even in the most high-traffic areas. When pets and kids run on lawns, they may trigger soil compaction issues.

If you’ve bought a new home, you should know that new home lawns often have buried or stripped topsoil. As well, grass which is put onto subsoil will probably have compaction because of traffic from construction. For this reason, new homeowners should seriously consider utilizing lawn aeration techniques.

If your lawns seem to dry out regularly and it has a texture which is sponge-like, it’s possible that there is an issue with excess thatch. To alleviate the problem, use a shovel to take away a slice of the lawn which measures about four inches in depth. If your layer of thatch exceeds a half inch, you should aerate. It will help greatly.

Lastly, if your lawn was created with sod and there is a layering of soil, aeration may be a smart choice for you. A layering of soil indicates fine-textured soil (which is typically found with sod that is imported) and which is layered over coarser soil (which was already present at the property). This type of layering is counterproductive to superb drainage, as water tends to be retained by the fine-textured soil.

This causes compaction and contributes to sub-par development of roots.

When you aerate, you’ll give water the capacity to flow freely throughout soil and get to the roots, where it needs to go. You’ll stop the layering problem in its tracks.

When Should You Aerate the Lawn?

Aeration is recommended while the growing season is going on. It’s a time when grass is ripe to recover well. It will fill up open areas once plugs of soil are taken away. For this reason, we think that aerating your lawn with “cool season” grass during the beginning of spring or autumn is smart. If you have “warm season” grass, you should shoot for aeration during the latter part of spring.

Get the Right Tools for the Job

When it comes to aeration, you’ll have a choice of a spike aerator or a plug aerator. These are the two main forms of tools for aeration. With spike aerators, you will have to utilize the spike aerator tool in order to make holes in the soil via a solid tine or fork. When you choose a plug aerator, you’ll take away soil and grass plugs from your landscape.

To get optimal results, utilize a machine or tool for aeration which takes away soil plugs. Poking holes really doesn’t work as well and may actually cause compaction issues to intensify in the areas surrounding the holes. As you can see, we think that a plug aerator is the smartest buy!

When you shop around for the right tool or machine, look for one which takes away plugs of soil two to three inches deep. The plugs of soil removed should measure between half an inch and three-quarters of an inch (diameter measurement) and they should be about two to three inches from one another.

Leasing a machine is a possibility. A lot of garden supply stores and lawn supply stores offer these tools or machines for rental. If you rent, follow the directions that you’re given. Some people choose to economize by sharing the cost of the rental with neighbors who also wish to aerate their lawns.

How to Get the Job Done

To prepare for this type of lawn care job, be certain that your soil is sufficiently moist. Aerating very dry soil is extremely frustrating! To ensure good results, wait for a day where there was a rain shower the day before! Another option is watering your lawn one day ahead of lawn aeration.

A lot of machines for aeration cover a smaller amount of soil surface with each pass. This means that you’ll need to make many passes over the areas which are most compacted. Save energy and resources by leaving the non-compacted parts of your lawn alone.

The soil plugs that you take away should dry out and then be broken up. When you do this, your lawn should take on a manicured appearance. Its surface should appear more uniform. To break up the plugs effectively, strike them with the back of your take or run them over with your lawn mower.

Don’t bother adding a “pre-emergent” herbicide before you aerate. Some people think that this will help, but it’s not necessary.

After you aerate, you should practice good lawn care, including mowing, watering and fertilizing.

Now that you have the inside scoop on lawn aeration, you’ll be ready to move forward and get the job done right.
