Why Aeration in Spring is a Bad Idea (and what to do instead)

As a lawn care company, we get asked all the time: "Can I aerate in the spring?" The short answer? You could… but you really shouldn’t.

We get why people think spring aeration makes sense—your lawn is coming out of winter, and you want to give it a boost. But here’s the deal: aerating in the spring actually works against everything you’re trying to do. If you care about having a thick, weed-free lawn, fall is the way to go. 

Why Fall is the Best Time to Aerate

1. It Won’t Mess Up Your Weed Control
   In early spring, we use a product called a "pre-emergent"  to stop crabgrass and other weeds before they sprout. If you aerate after that - You punch holes right through the weed barrier and basically invite weeds to take over your lawn.

2. Stronger, Healthier Grass
   Aerating in the fall lets your lawn breathe, take in nutrients, and develop deep roots before winter. Then, when spring rolls around, your grass is already strong and ready to go.

3. Perfect Timing for Overseeding
   If you want to thicken up your lawn, fall is the time to do it. Overseeding is adding new grass seed to a lawn. It works really good when there’s no competition from weeds, and aeration helps those seeds settle in and grow. In the spring, you can’t seed because—you guessed it—pre-emergent stops grass seed from germinating too.

4. Better Soil Conditions
   In fall the ground temp is cooler, which means your lawn actually gets the most benefit from the process. In spring, the ground is often too wet, making aeration less effective.

Why Spring Aeration is a Bad Idea

We’re not saying spring aeration is completely useless—but for most lawns, spring aeration creates more problems than it solves.

1. It Wrecks Your Pre-Emergent – If you aerate in spring, you break the weed control barrier and give weeds the perfect opportunity to grow.

2. It Encourages Weeds – Not only does it mess with pre-emergent, but it also gives weed seeds direct access to the soil. If you want a weed-free lawn, spring aeration is working against you.

3. It Stresses Out Your Lawn – In early spring, your lawn is focused on growth, not recovery. Aerating too soon can actually slow it down instead of helping.

4. You Can’t Overseed Anyway – Because of the pre-emergent issue, you’re stuck with any bare spots until fall. If your lawn looks patchy after aeration, there’s nothing you can do about it for months. 

What You Should Do in Spring Instead

Instead of aerating, focus on what actually helps your lawn thrive in the spring:

• Pre-emergent weed control – Keeps weeds like crabgrass from sprouting in the first place.
• Proper fertilization – Gives your grass the nutrients it needs to green up and grow strong.
• Regular mowing – Cutting at the right height helps prevent weeds and keeps your lawn thick.
• Fix bare spots later – If you have thin areas, wait until late summer or early fall to overseed. Good news, with enough nutrients Kentucky blue grass can fill in bare spots through rhizomes - grass spreading underground. 

Final Thoughts: Save Aeration for Fall

If you want a healthier, weed-free lawn, fall is the time to aerate. It sets your lawn up for success without messing up weed control, gives roots time to develop before winter, and works perfectly with overseeding.

In the spring, stick to weed prevention, fertilization, and mowing, and let aeration wait until fall when it can actually do some good.

If you’re ready to get on the schedule for fall aeration, give us a call! The earlier you plan, the better your lawn will look next year.
