A great lawn is a major source of pride in homeowners. The problem is that while an awesome looking lawn is great to have, it’s sometimes a frustrating journey to get there.

One major part of getting that beautiful lawn is knowing the best time to aerate. Reading on, you can learn all about lawn aeration and when the best time to have this project completed around your home.

What is aeration and why is it important?

In order for grass to thrive, the grass roots need the proper amounts of air, nutrients, and water. If the soil gets compacted, these things cannot reach the root. When these essential nutrients and water cannot get to the root system, you won’t get that thicker and healthier growths of grass. What aeration does is to perforate the soil with small holes to allow the water, nutrients, and air to get to the roots of the grass. The end result is that you get a strong and more lush lawn.

There are plenty of benefits to investing in aeration services for your lawn. These benefits include:

Reducing soil compaction

The clay soil that is common in Pennsylvania easily gets compacted. Aeration can reduce this compaction and improve the structure of the lawn. When the soil is compacted, this prevents the necessary circulation of air, water, and nutrients for a thriving lawn.

Breaking through thatch

Thatch is naturally occurring organic material that is dead, which builds up on your soil. Any buildup of thatch that is over ½ inch thick prevents water, air, and nutrients from getting through the soil to the roots. Not only can this impact the quality of the grass roots, but it can also lead to a variety of other issues including pests or disease. Lawn aeration can break up the thatch and help increase the microorganisms that can cause the decomposition process of the thatch.

Improves results of overseeding

If you plan to overseed your lawn this year, it's recommended that you plan to do it after your aeration service. Overseeding is more effective when completed along with aeration services because there will be better seed-to-soil contact due to the tiny holes created in the soil from aeration.

Improves results from fertilizer treatments

Looser soil that is gained through aeration can make any fertilization treatments that you receive more effective. This is because the fertilizer will be able to penetrate deeper into the soil. This results in a nicer looking lawn.

Better weed control

You are less likely to have weeds if you have a regularly aerated lawn. This is because when you have a lush, healthy lawn, the thickness of the grass prevents unwanted weed growth by crowding out weed populations. You can also benefit from this because you will spend less on weed control measures.

When to aerate lawn in PA?

Before getting into when you should aerate your lawn, it’s important to talk about how often you should be aerating your lawn. The answer depends on the texture of your lawn’s soil. There are typically a few different categories for soil: clay, loam, and sand. Clay soil particles are the smallest of the 3, which is why this type of soil can be compacted more easily than the other types of soil. Since clay soil is very common in areas of Pennsylvania, this means that aeration should be performed on an annual basis. Other types of soil may be able to go without aeration every other year.

One of the reasons that you should hire a lawn care professional is that they can look at your lawn and determine what the best approach is to get the picturesque green lawn that you’ve been dreaming of. This includes determining what type of soil you have so that you know whether or not you need yearly aeration services or if you can get these services every other year.

As for the best time to aerate your lawn, there is some disagreement amongst experts. The general consensus is that this should be done while the soil is still warm. This means that the best times for aeration are either spring or early fall. Depending on the lawn care company, you will get a different answer.

Generally speaking, fall is widely considered to be the best time for lawn aeration in PA. This is because fall is the growing season, between September and October. But you may also find great results when you choose aeration during the cool season found during early spring.

If you do decide to go with fall aeration, you should schedule fall seeding at the same time. Aeration during fall is the popular choice because this can be an essential tool in helping to repair your lawn after the wear and tear caused by the warm summer months. You can cause a rejuvenation in your lawn that will give an excellent foundation when the warmer weather hits again in the following spring.

You should be sure to follow any instructions provided by your lawn care professional after you receive your aeration services. For instance, if you decide to seed on your own, you will want to seed as soon as possible after your aeration services. You should also go through the seeding process again as spring hits. By doing this, you will get the best results from your aeration.

Lawn care does require some patience. You won’t notice immediate results, especially if you don’t follow the lawn care recommendations as offered by your lawn care professional. Slowly, aeration and proper lawn care will make for a healthier lawn that you can love for a long time to come.
