Will Aerating Lawn Help Drainage

If you have a lawn, it’s no wonder you want it to look its best. A beautiful, green lawn is the perfect backdrop for outdoor gatherings and a source of pride for any homeowner. 

But achieving and maintaining a healthy lawn can be a challenge, especially if your soil is compacted or if drainage is an issue. Lawn aeration can help with both of those problems and more, making it an important part of any lawn care routine. Here’s everything you need to know about aerating your lawn.

What is aeration? 

Aeration is the process of perforating the soil with small holes to allow air, water, and nutrients to reach the roots of your grass. Over time, soil can become compacted, which prevents these vital elements from getting down to where they’re needed most. Aerating your lawn helps to mitigate compaction and promote a healthy root system. 

Introduction to Aerators

An aerator is a tool that is used to create small holes in the soil. This allows air, water, and nutrients to reach the roots of plants more easily. Aerators come in many different shapes and sizes, but they all work by using sharp blades or tines to puncture the ground. 

There are two main types of aerators – manual and power-assisted. Manual aerators look like long-handled forks with spikes on the end. You simply insert the spikes into the ground and push down, making small holes as you go. 

Power-assisted aerators, on the other hand, do all the work for you. They’re usually gas-powered and look somewhat like a power lawnmower. Both types of aerators are effective, so it’s really just a matter of personal preference as to which one you choose. 

Does Aeration Help Drainage? 

There is no definitive answer to this question. Some studies have shown that aeration can help improve drainage, while others have shown that it doesn’t make a difference. One study showed that aeration increased infiltration rates by 17%. 

Another study showed that there was no significant difference in infiltration rates between aerated and non-aerated sites. The jury is still out on this one, but if you have problems with drainage, it couldn’t hurt to try aerating your lawn. The worst-case scenario is that you’ll end up with some extra holes in your lawn! 

When should I aerate my lawn? 

The best time to aerate your lawn is in the fall after the growing season has ended but before the first frost. This gives your grass time to recover from the stress of being poked full of holes and also allows any new seedlings ample time to take root before winter sets in. 

However, aerating in spring can also be beneficial, as it helps to loosen up compacted soil and allows new grass seedlings to take root more easily. No matter when you choose to aerate, the important thing is to do it regularly, as this will help keep your lawn looking its best. 

That said, if your lawn is particularly compacted or if drainage is an issue, you may need to aerate more than once a year. 

How do I know if my lawn needs aeration? 

There are several telltale signs that indicate it’s time to bust out the aerator. If your grass has trouble growing or seems thin in spots, that’s a good indication that compaction may be an issue. 

If puddles form on your lawn after a rainstorm or if water pools around outdoor fixtures like AC units, that’s another sign that drainage could be improved by aerating. Finally, if footprints or tire marks remain visible on your grass long after they’ve been made, that means the ground is too compacted for proper air and water exchange – meaning it’s time to break out the spikes! 


Aerating your lawn may seem like a daunting task, but it’s really not that difficult – and it has some big benefits for your grass. By promoting air and water exchange at the roots, aeration can help improve drainage issues and alleviate compaction for a healthier lawn overall. 

We hope that now you have a better understanding of lawn aeration and how it can help your landscape. Good luck! So grab an aerator (or rented one) and get started! Your grass will thank you for it.
