Is your yard getting you frustrated? Have you tried everything, but your yard still looks weak and thin? The problem may not be what you think. When soils suffer from compaction, it can often cause symptoms attributed to other problems. If you have tried everything to no avail, then maybe you should consider lawn aeration and following it up with an overseeding.


As we spend time outdoors running and playing on our grass, it can cause the soil to become compacted. Another contributing factor to soil compaction is the buildup of grass clippings and other organic material under your grass, also known as thatch. This hard soil is packed so tightly that it does not allow water, air, or nutrients to pass through it.

This can cause your grass to appear as if it doesn’t have enough water, which it doesn’t. But the answer isn’t to water it more — the answer is to aerate. Aeration is the process of using a machine to pull up hundreds of tiny plugs of sod. This loosens the soil, allowing water, air, and fertilizer to reach the roots of your grass.

Signs Your Yard Needs to be Aerated

If you are unsure about what is causing your grass to look so weak and unhealthy, look for the signs:

Pooling Water: 

Is there a constant puddle of water in your yard after it rains or year-round? This could be a sign that your soil is compact and is preventing water from being absorbed into the ground.

Spongy Grass: 

Does your grass feel like you are walking across a mattress? That is a sign that you have thick thatch buildup that retains moisture and can lead to diseases, and it can also be an inviting home for pests.

Compacted Soil: Stick a screwdriver 6 inches into your soil. Is it hard or easy? If it’s difficult, then that means your soil is compacted and could use a good aeration.

When Is The Best Time for Lawn Aeration?

Generally, we recommend aerating your yard twice a year — in the spring and fall. The proper time to aerate depends on two conditions: the type of grass you have and the weather.

Warm-season grasses like zoysia grass should be aerated in May and June. Cool-season grass like Kentucky bluegrass, perennial ryegrass, and fine fescue should be aerated in the fall.


If you are struggling to get your grass to look thick and healthy, try overseeding. Aerating is usually followed by overseeding to help get the grass thicken up. The fresh holes left from lawn aeration are perfect for growing new grass from seeds.

The optimal time to overseed in Michigan is early fall, when soil temperatures are still warm but the air temperatures are cooler. During this time, there are less weeds growing and competing for space and nutrients.

The Benefits of Over-seeding

Overseeding brings with it a host of benefits, including:

Reduced Erosion

The root systems of grass prevent soil from being washed away in the rain.

Improved Appearance

Overseeding is the answer to bare spots and inconsistent areas that stand out. 

Reduced Risk of Pests, Disease, and Drought

Overseeding with different varieties of grass you can increase your yard’s tolerance to drought, diseases, and pests.
