The Benefits of Spring Aeration for Your Lawn (and Why You Probably Shouldn’t Do It)

Let’s be honest—spring feels like the season to do aeration for your lawn.

The sun’s coming back, flowers are blooming, and you’re ready to roll up your sleeves and get your yard in shape. If you’ve Googled “spring aeration near me,” you’re not alone. At Blue Duck Lawn Care, our phones start ringing nonstop with requests for spring aeration and overseeding this time of year.

 

And while we love a homeowner who wants to invest in their lawn, spring aeration is rarely the smart move.

Yes, there are benefits to aerating your lawn. But just because something has benefits doesn’t mean it’s the right solution—especially in Central Indiana’s climate and growing conditions.

Let’s break it down.

___________________________________________________________________________________________________________________________________

What Is Spring Aeration (and Why Do People Do It)?

Aeration is the process of removing small plugs of soil from your lawn to relieve compaction and allow air, water, and nutrients to penetrate deeper into the root zone.

It’s commonly paired with overseeding—drop the seed in the holes, and you create the perfect place for germination.

Sounds good, right?

Yes, but only at the right time.

So… Is Spring Aeration a Bad Idea?

In most cases—yes. Here’s why.

___________________________________________________________________________________________________________________________________

1. Spring Aeration Breaks Your Weed Barrier

In spring, your lawn is waking up, but so are the weeds. That’s why lawn care professionals apply *pre-emergents* during this season—a special treatment that creates an invisible barrier over the soil, preventing crabgrass and other weeds from sprouting.

Now imagine you go and poke hundreds of holes in that invisible barrier.

That’s exactly what spring aeration does—it punches holes in your weed shield. You’ve now created a perfect pathway for weeds to bypass that pre-emergent and take over your lawn.

So while your intent was to improve the soil, what actually happens is you invite a weed infestation.

2. Spring Aeration + Overseeding = Wasted Money

Many homeowners pair spring aeration with overseeding (because that’s what the big box stores tell you to do). But here’s the problem:

You can’t seed and apply weed control at the same time.

If you seed after aerating, you’re now committed to a no-weed-control policy for the next 60 days. Otherwise, you’ll kill your new grass.

So now your new seed has to go toe-to-toe with weeds… and it’s going to lose.

And even if it grows? Come July, it’s not going to survive.

3. Summer Heat Will Burn Your Efforts

Grass seeded in the spring rarely develops deep enough roots to survive Indiana’s summer heat and drought conditions. Even if your new grass gets off to a decent start, most of it will die before fall.

We typically see an 80–90% failure rate for spring-seeded grass in Central Indiana.

So unless you want to throw money at something that has a 10% success rate and still leaves your lawn full of weeds—save your budget for the fall.

But What About Golf Courses? They Aerate All the Time!

Yes, and they also spend over $100,000 per hole every year on specialized maintenance, irrigation systems, and full-time staff.

Unless you have a golf course budget, that’s not the comparison to make.

Is There Any Reason to Aerate in Spring?

There are rare exceptions.

If you have:

• Heavy soil compaction that’s choking out grass.
• Significant damage from construction or pets.
• A special event like a wedding where you need grass now, and you understand it’s a short-term fix…

Then yes, aeration might be warranted—but understand the risks and the likelihood that you’ll be redoing the work in the fall.

The Real Best Time to Aerate? FALL.

Fall is hands-down the best time to aerate and seed your lawn in Indiana.

• Weeds are slowing down.
• Temperatures are ideal for root growth.
• Soil stays moist longer.
• Grass has months to establish itself before its first summer.

When you aerate in the fall, you set your lawn up for long-term success—not a short-lived spring fling with grass seed that dies off in July.

Bottom Line: Work With Nature, Not Against It

At Blue Duck Lawn Care, we always say this: nature always wins. Your job (and ours) is to work with it, not against it.

Aerating in spring might seem like a good idea, especially when the ads and sales are everywhere. But if your goal is thick, green, weed-free turf that lasts, then spring aeration is likely to do more harm than good.
