If your formerly lush, green lawn looks stressed, your soil feels dry and spongy, and your grass is puddling after it rains, you may need to aerate. Lawn aeration is the process of perforating your lawn with tons of holes to break up your soil and let it breathe, allowing water, air, and nutrients to seep in.

You can aerate yourself by renting equipment, or you can hire a lawn care company to take care of it for you. In this lawn aeration guide, we break down how to aerate your lawn, how often this maintenance is needed, top lawn care companies that provide aeration services, and

What Is Lawn Aeration?

If your soil has become compacted, it’s time to aerate. Dense and tightly packed, compacted soil inhibits root growth by cutting off access to nutrients. Soil compaction also encourages weed growth and makes lawns more vulnerable to drought. Here are some factors that might increase the likelihood of soil compaction:

  • High clay content – Clay soils are more likely to become compacted than sandy soils because they’re heavier.
  • New construction – If your lawn was established as part of a new home, its topsoil may be buried, and construction workers may have stepped on and compacted the subsoil.
  • Foot traffic – Lawns that get a lot of foot traffic may become compacted.
  • Sod and soil layering – If you have a sod lawn, you may have soil layering—meaning the sod’s fine soil was placed on top of coarse soil when it was installed. These inconsistent layers can reduce drainage, which can cause compaction and make it difficult for root systems to grow.

If you’re not sure, simply pull out your toolkit and perform the screwdriver test. If you can easily slide your screwdriver several inches into your lawn’s soil surface, you’re good. If you’re met with a lot of resistance, you have compacted soil.

When to Aerate Your Lawn

How often you aerate depends on the conditions of your lawn. If you have a sandy soil, you probably don’t need to aerate more than every two to three years. But if you have a heavy clay soil, your lawn could benefit from aeration every year—or even twice a year, if it gets heavy foot traffic.

The time of year you aerate depends on your grass type. Lawn aeration is most effective during a grass’s growing season, allowing it to heal more quickly. You should aerate cool season grasses like fine fescue and Kentucky bluegrass in early fall or early spring. Warm season grasses, like Bermuda grass and St. Augustine grass, should be aerated in late spring, or early summer at the latest.

You should never aerate soil that’s overly dry. Soil that’s a little moist is ideal—too wet, and aerating will be a mess. If you can, aerate the day after it rains, or a day after you’ve watered your lawn.

Dethatching Before Lawn Aeration

Before you start the process of lawn aeration, you’ll need to dethatch. Thatch is a layer of decomposing organic matter that sits between the grass and soil. If it builds up to a layer that’s greater than ½ inch, it can block your grassroots from absorbing water, air, and nutrients—just like compaction.

Dethatching is an easy process. You can use a regular rake or dethatching rake to break up and remove the thatch layer. Once you’ve removed this barrier and have a smooth surface, you can start aerating.

How to Aerate Your Lawn

If you decide to aerate your lawn yourself, you’ve got several options, ranging from spiky shoes to sophisticated machinery. Your choices of aeration equipment include these:

  • Aerator shoes
  • Core or plug aerators
  • Garden forks
  • Spike aerators
  • Slice aerators

Garden Fork

A savvy DIY-er might kick things off with a simple garden fork, puncturing the soil in 3-4 inch intervals. This can be a time-consuming approach, but it’s budget-friendly. If you have a large lawn, this can get tiring quickly.

Aerator Shoes

Lawn aerator “shoes” have spikes on the bottom. You strap these spiky sandals to your regular shoes and walk around your lawn, poking holes as you go. Average aerator shoes range from $10 to $25.

Core aerator

Also called plug aerators, core aerators cut little holes and remove “cores” or plugs of dirt from your soil through hollow tines. These plugs are usually about 2-3 inches deep, but it depends on the machine. The plugs should be removed about every three inches.

After removing the soil plugs from your soil, you can break them up with a rake or garden fork and leave them to decompose, adding nutrients back into the soil to promote grass growth.

Spike aerator

Spike aerators simply puncture holes in the soil with solid tines—the same principle as aerating shoes. These aerators help a little, but they can be counterproductive. If the soil around these holes get pressed together too closely, you’re back to square one.

Slice aerator

These are the least common. They slice right through the grass with their blades, giving grass access to water, air, and nutrients. It’s a similar theory to spike aerators, but it doesn’t risk further compaction.
