3 Secrets For a Thicker Lawn: Aeration, Overseeding, & Topdressing (2024)



Achieving a truly great-looking lawn is a multi-step process that goes beyond a typical lawn care regimen. When you’re investing in professional lawn care, you want to have great results but, unfortunately, some homeowners skip over the steps that would take their lawn to the next level.

Those often-overlooked steps include lawn aeration, overseeding, and lawn topdressing - 3 steps that pros are taking on professional sports turf (like golf courses or athletic fields) in order to achieve amazing results.

We’ll explain how each of these plays a critical role in lawn thickness and health and might be the services that truly take your lawn to a whole new level of “wow.”

1. Lawn Aeration

Professional lawn aeration is one of the most valuable services you can have performed on your lawn. That’s why we call it the “cornerstone” of our lawn care program.

During lawn aeration, a professional core aerator is used to extract small cores from the soil and leave them there to break down and filter back into the earth. This process allows more water, oxygen, and nutrients to penetrate down to the lawn’s root zone, where they’re needed most.

Due to the clay-like soil in our region and the fact that it is frequently compacted, it’s fair to call this service a “necessity.” We feel that if you’re investing in lawn care services, you should also invest in lawn aeration in order to get the most out of your investment. If you don’t, you’re simply not going to get the full value that you’re seeking.

2. Lawn Overseeding

It’s important to note that professional lawn aeration and overseeding should be performed at the same time to achieve the best possible results. When overseeding is performed at the same time, it allows the seeds to fall into the holes created by the aerator and generate better seed-to-soil contact. This will help you to grow a thicker and healthier lawn.

While some homeowners ask why they can’t just seed on their own, there is a big difference between professional-grade seed and the seed that homeowners can purchase on their own.

Grass seed sold at box stores is not always clean and may even have filler mixed in. With low-grade seed, you wind up growing weeds and paying extra money for weed control (essentially shooting yourself in the foot). That’s why it’s important to have both professional lawn aeration and professional seeding performed together.

3. Lawn Topdressing

Topdressing is another important but often overlooked service that can help produce a lush, green lawn. After lawn aeration and seeding are performed, we will topdress the lawn with compost, allowing it to fall into the holes we made. As the compost mixes with the clay, it helps create a better layer of topsoil by improving soil structure and microbial life.

Lawn topdressing should be performed right after aeration as it’s not nearly so useful to do it without the holes already there. As mentioned, the idea is for the topdressing to mix in with the existing clay soil. When this is done, it can be the difference between a lawn that looks great and one that looks spectacular!

A Word on Power Seeding

For the average lawn, aeration and seeding, followed by topdressing, will be enough. However, when aeration and overseeding are not enough, a service called power seeding might be necessary.

Power seeding, which is also often referred to as “slice seeding” or “slit seeding,” is an intensive process that is performed on golf courses. It uses a piece of machinery to cut rows into the soil to plant the seed, just like rows of crops. Power seeding is highly effective at filling in bare spots. Homeowners are often shocked at just how drastic the results of slice seeding can be. It can really transform an entire lawn.

Choosing a Lawn Care Company for the Best Results

3 Secrets For a Thicker Lawn: Aeration, Overseeding, & Topdressing (4)There’s nothing worse than feeling like you’ve invested time and money into a lawn care company or service that isn’t producing the fantastic results that you’re after. But the truth is, a lot of times this is because the homeowners are not taking the next steps and choosing to include lawn aeration, overseeding, and topdressing in their lawn care package. It is these steps that really can take a lawn to a whole new level.

Of course, you want to choose the right company for the work.

Investing in a lawn care professional to perform these services will ensure the work is performed right and that you get the best possible results. It will also ensure the work is done when the timing is right. If you try to perform these services on your own or you work with a questionable lawn care service, poor timing, or service performance could easily lead to subpar results.

But at Kingstowne, we will make sure that all three of these valuable services (and possibly power seeding) are performed the right way so that you can get the greenest and healthiest grass possible. After all, if you’re investing in lawn care, you deserve to get fantastic results. The last thing that you should have to do is spend any time worrying about why your lawn isn’t looking its best.

FAQs

Do you top dress or aerate first? ›

Topdressing the lawn should be done right after aeration as it's not nearly so useful to do it without the holes already there. As mentioned, the idea is for the topdressing to mix in with the existing clay soil.

Does aeration help thicken lawn? ›

Not only does aerating your lawn allow more nutrients, water, and sunlight to pass through, it also stimulates the development of your grass roots. This, in turn, helps your grass grow thicker, stronger, and stay green longer during a dry spell.

Does cutting grass short make it thicker? ›

Mowing short – If you mow short (not too short), your grass will learn to grow thicker with more lateral growth. If you leave it too long, once again sun can't penetrate as easily, and you end up with a patchy lawn, particularly when you end up cutting off more than a third of the leaf to bring the level back down.

Does milorganite thicken grass? ›

Milorganite will be great for the new seed and its initial push, but it will also help your existing lawn to green and thicken up right alongside it. Cool-season lawns push roots in fall time naturally anyway and Milorganite will support and encourage it to push more!

Can you put down too much overseed? ›

Ignoring recommended seeding rates

Quality grass seed labels include guidance on optimal seeding rates to maximize your results. Don't overdo or cut corners. Too much grass seed causes undue competition for resources such as light, water and nutrients, and grass seedlings struggle as a result.

What is the best seed for thickening grass? ›

In general, Kentucky Bluegrass, Tall Fescue, and Bermudagrass are excellent choices for most lawns. Kentucky Bluegrass has that traditional lawn aesthetic, while Tall Fescue offers excellent durability, and Bermudagrass provides quick coverage and drought resistance.

Can I just throw grass seed down on an existing lawn? ›

Overseeding can help you get back to the thick, lush, green lawn you've always wanted. By spreading grass seed over your existing lawn, you can thicken up the thin areas, and your lawn will start to look terrific again. (This is different from reseeding, which is when you start over and plant a completely new lawn.)

What month should you aerate? ›

For cool-season grasses common in northern lawns, early fall or early spring are the best times for aerating. For warm-season grasses common to southern lawns, the best time for aerating is late spring or very early summer.

Should I put topsoil down after aerating? ›

After aerating, it's time for top dressing: spread either pulverized top soil or a good quality humus compost across the lawn. You don't need much—about a quarter inch or so is adequate. Then, go ahead and reseed.

What should I put on my lawn after aerating? ›

It's best to apply fertilizer right after completing the aeration process, or within a few days. We recommend purchasing a fertilizer with a balanced nitrogen, phosphorus, and potassium ratio (NPK) that's suitable for your grass and soil type. It's always best to test your soil before applying fertilizer.

How do I make my lawn super thick? ›

If you're looking for thicker grass, then you'll also want to make sure that you're having aeration and overseeding performed at your property. One of the main reasons to aerate your lawn is to alleviate soil compaction.

Will aeration fix a bumpy lawn? ›

As we talked about earlier, aeration is an essential part of leveling a bumpy lawn. Over time, weather, wildlife and regular wear-and-tear can cause the soil to become compact, preventing your lawn from getting the nutrients it needs. To reverse this, aerate!

Is too much aeration bad for lawn? ›

You can over-aerate. Over-aerating your lawn can stress out your lawn and leave you with uneven soil. Even though it can be damaging to over aerate your lawn, it is actually quite difficult to aerate too much. It is recommended to have your lawn aerated once or twice a year.

What is the really thick grass called? ›

Those thick blade grass clumps you might find are not a normal part of your lawn. They're a weed called fescue.

What is the fastest growing thick grass? ›

The fast-growing warm-season grasses include Bermuda grass, centipede grass, and buffalograss. Bermuda grass seeds germinate in 10 to 30 days and form a dense, dark green established lawn within six to 11 weeks of seeding.

How long does it take to grow thick grass? ›

Whether you're repairing bare spots, overseeding an existing lawn or starting from scratch, you can generally expect grass seedlings to emerge within seven to 21 days when grown under proper conditions. It may take another three to four weeks of growth before grass is long enough to mow.

How do you dig up thick grass? ›

If you prefer a natural option, you can dig up a lawn with a tiller or sod cutter. Buying a tiller will make the work easier, but you'll need a heavy-duty, rear-tine model. You can rent a heavier grass-removal tool, such as a sod cutter, which will cut under the turf and slice it into strips.
