But one of the common questions I get is does liquid aeration work? Yes, it does! Liquid aeration involves applying a specialized aeration solution to the lawn. This solution typically contains a combination of surfactants, soil penetrants, and other ingredients like ammonium lauryl sulfate.

How Does Liquid Aeration Work?

Liquid aeration solutions are simply mixed with water sprayed with a hose-end sprayer, broadcast sprayer, backpack pump sprayer, or garden sprayer.

These solutions are powered by ammonium lauryl sulfate – a substance that’s classified as an anionic surfactant, given it holds a negative ionic charge.

Ammonium lauryl sulfate cuts into clay soils and also serves as one of the best liquid soil conditioners. After spraying this liquid soil aerator on your lawn, it starts breaking down the dense soil particles and creates small holes to help loosen the soil.

These holes allow air, water, and essential nutrients to be absorbed easily by the soil and promote healthy root growth.

How Long Does it Take for Liquid Aerator to Work?

Liquid aerators don’t provide immediate effects but continual applications are needed for sustained results. In terms of numbers, it can take anywhere between 45 and 60 days for the enzymes in liquid aerators to make a difference in the soil.

Some liquid aerator manufacturers add other ingredients such as amino and humic/fulvic acid to speed up the process.

Liquid Aeration vs. Core Aeration – Which is Better?

There’s a lot to consider when choosing between liquid and core aerations as one may work better than the other depending on your needs and goals.

Core Aeration

Let’s start with core aeration – a process of pulling plugs of soil with an aerating tool or machine. Core aeration works almost instantly to provide relief for your lawn.

So, if your lawn is looking beat up after a harsh summer, core aeration is a good option. However, core aeration leaves unsightly holes in the ground.

Using an aerator machine over your lawn can leave your turf looking like a battlefield with unsightly plugs. But on a brighter note, these holes aren’t permanent and will disintegrate over time.Read more about the benefits of core aeration.

Liquid Aeration

Compared to core aeration, liquid aeration can be applied easily with a pump sprayer or a hose-end sprayer. Adding to this, liquid aerating solutions aerate your lawn in a matter of minutes whereas pushing a manual aerating machine can be a tiresome and daunting task.

Another key benefit of liquid aeration vs core aeration is its broad coverage but you may have to aerate the same area several times with a core aerator.

And to top things off, liquid aeration is much cheaper than core aeration given there are tools to buy or rent and you don’t have to call professional help.

Liquid Aeration Pros and Cons

Liquid Aeration Pros

  • Quick applicationPerhaps the biggest benefit of liquid aeration is that it can be spread quickly and reach the grass roots quickly.
  • Can be used on a variety of lawn types and sizesRegardless of the type of grass or the size of your lawn, liquid aeration can work wonders with proper application.

Liquid Aeration Cons

  • May not be as effective as traditional aeration methods – Many avid gardeners believe that liquid aeration offers the same or better effectiveness than traditional aeration methods, but this isn’t completely true.Core aeration provides immediate results in a heavily compacted lawn but the effects aren’t very long-lasting. This type of aeration pulls plugs or “cores” of soil from your lawn and is a great choice for newly sodded lawns and lawns riddled with moss plants. Unlike core aeration which produces almost instant results, liquid aeration takes time to work Adding to this, liquid aerators don’t work well in lawns with excess thatch that’s over 1/2 inch thick.
  • More expensive than traditional aeration methods – Liquid aeration is cheaper only if you don’t own the equipment needed for core aeration. With core aeration, you either have to rent an aerator machine or rent one, both of which can be a pricey affair somewhere around $200.
  • Unlike core aeration which produces almost instant results, liquid aeration takes time to work.
  • Adding to this, liquid aerators don’t work well in lawns with excess thatch that’s over 1/2 inch thick.

How Much Does Liquid Aeration Cost?

Liquid aeration can cost as little as $35 for up to 35,000 square feet of coverage. Contrarily, calling a lawn care professional for core aeration can vary between $200 and $350, which isn’t a market price that’s easy to digest.

How to Liquid Aerate Your Lawn?

The process of liquid aerating your lawn is similar to applying liquid fertilizer, where you mix the product with water, fill up an irrigation sprayer, garden pump sprayer, or even a household sprayer, and spray the solution across your yard.

After successful application, it can take up to 45 days for the liquid aeration solution to work so you’ll have to be patient for the enzymes to make a difference in your soil.

Homemade Liquid Aerator

I recommend that you buy a tried and tested liquid aerator from your local garden center or online instead of making a homemade solution.

Liquid aeration products use dish soap as a surfactant but its concentration with the other ingredients is unknown. Just make sure that the soap you use doesn’t have any antibacterial stuff in it otherwise you could kill the beneficial microorganisms in your lawn.

When to Apply Liquid Aeration?

The best time to apply liquid aeration is in the spring or fall. This is typically the time when grass growth is at its best, which makes it easier for your lawn to recover.Check out my detailed article on the best time to aerate your lawn.

After applying the liquid aeration product properly, thoroughly water your turf immediately and for the next two weeks according to your regular watering schedule.

How Often Should You Use Liquid Aeration?

You can liquid aerate your lawn every two weeks if you need to. However, it’s best to wait for 2 – 3 weeks after the first application to get to the lawn’s root system before applying another round of liquid aerator products.


Q. Is Liquid Aeration Just Soap?

A. Even though liquid aeration contains ammonium lauryl sulfate – the active ingredient in soap, it does contain other ingredients in its formulation such as but not limited to hydrogen peroxide.

Q. Do I Need to Water After Liquid Aeration?

A. Yes, you need to water your lawn thoroughly after liquid aeration so that the product can be absorbed by the roots as soon as possible.

Q. Does Liquid Lawn Aeration Work on Compacted Soil?

A. Liquid aeration is similar to core aeration in that it stimulates microbes and starts breaking down dense and compact soil.

Q. Can you Seed after Liquid Aeration?

A. You can overseed after liquid aeration. Liquid aeration creates the perfect environment for overseeding your lawn.But make sure you have healthy soil in your lawn before overseeding.

Q. Is Liquid Aeration Safe for Dogs?

A. Most liquid aeration products are safe to use around kids and pets. However, it is best to read the manufacturer’s label to ensure it is safe to do so.

Final Thoughts

Liquid lawn aeration is the new kid on the block but is quickly becoming the preferred choice for many homeowners and a professional lawn aeration service.

Mechanical core aeration or traditional core aeration requires a fair bit of effort, but a liquid aeration product is a solution that can be applied easily with just a handheld sprayer.
