First, make sure you have compacted soil (see Signs You Have Compacted Soil<\/a>), then we’ll show you how to fix it. Learn How to Test for Compacted Soil<\/a> to help you determine your soil’s condition. <\/p>
1. Core Aeration<\/h2>
![\"an](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2022\/10\/aeration.jpg\")
Infographic by Juan Rodriguez<\/figcaption><\/figure> Aeration makes small holes in the soil that improve absorption and drainage. It also loosens the soil structure, helping roots stretch out, but you\u2019ll need to combine this with soil amendments to fix compacted soil.<\/p>
Best for:<\/strong> Yards of any size, particularly yards with clay or silty soils that are most prone to compaction.<\/p>
Effort:<\/strong> Moderate<\/p>
Timeline: <\/strong>30 minutes to a few hours<\/p>
What you\u2019ll need:<\/strong><\/p>
- Manuel aerator<\/li>
- Electric or gas-powered aerator (best for large areas)<\/li> <\/ul>

- For cool-season grasses<\/strong>, aerate in the fall.<\/li>
- For warm-season grasses<\/strong>, aerate in the late spring to early summer.<\/li> <\/ul>
Aeration requires expensive equipment and takes time, so hire a LawnStarter pro to aerate<\/a> your lawn and save you the hassle of fixing compacted soil yourself.<\/p>
2. Loosen Soil Manually<\/h2>
![\"A](\"https:\/\/www.lawnstarter.com\/blog\/wp-content\/uploads\/2024\/11\/dig-soil.jpg?wsr\")
Photo Credit: Paradee<\/a> \/ Adobe Stock generated with AI<\/figcaption><\/figure> Sometimes, soil is so compacted that regular home-use aerators bounce off the ground and barely chip the dirt. If your lawn is too difficult to aerate, you might need to dig the soil up with a shovel or a rototiller.<\/p>
Best for: <\/strong>Small yards, around delicate plants, in plant beds, or areas where aerators can\u2019t reach<\/p>
Effort:<\/strong> High<\/p>
Timeline:<\/strong> 30 minutes to a couple hours<\/p>
What you\u2019ll need:<\/strong><\/p>
You will need a tool to till with:<\/p>
- Garden fork
Rototiller<\/li> - Shovel
Manual aerator<\/li> - Broad fork<\/li> <\/ul>
How to do it<\/strong>:<\/p>
- Garden fork:<\/strong> Till your soil once to loosen compact dirt. Push the tines of a garden fork into the ground. Rock the fork back and forth to loosen compacted soil. Don\u2019t over-till. It can worsen compaction. <\/li>
- Rototiller or shovel: <\/strong>Use a rototiller<\/a> or shovel to dig up the surface soil. By disturbing the soil, you allow nutrients, water, and air to filter into the soil again. <\/li> <\/ul>
After tilling, add compost and mix it into the soil with a rototiller or shovel. Then cover it with topsoil.<\/p>
3. Compost<\/h2>

Photo Credit: Vera Kuttelvaserova<\/a> \/ Adobe Stock Free \/ License<\/a><\/figcaption><\/figure> Compost improves the soil texture by adding organic matter. Organic matter acts as a binding agent, allowing soil particles to form small clumps and create openings in the soil.<\/p>
\u201cCompost can improve the tilth (the condition of tilled soil) and reduce compaction of the heaviest clay soils and increase the water retention and nutrient holding capacity of the sandiest of soils,\u201d Emerson says.<\/p>
Best for: <\/strong>Mild soil compaction<\/p>
Effort:<\/strong> Moderate<\/p>
Timeline: <\/strong>30 minutes to a few hours<\/p>
What you\u2019ll need:<\/strong><\/p>
- Compost
Gardening gloves<\/li> <\/ul>How to do it:<\/strong><\/p>
New builds or starting with bare soil:<\/strong> The easiest way to add organic matter is to mix compost into your soil<\/strong>. <\/p>
\u201cCompost can be added to a depth of 0.5 inches up to 6 inches\u201d in new-build subdivisions or total lawn renovations, Emerson says. \u201cYou must remember that the deeper the compost layer, the deeper the tillage should be. Once sufficiently mixed with the existing soil, final grading and planting can begin.\u201d<\/p>
Experts at the University of Florida say that a 1-inch layer of compost incorporated while tilling is usually enough to improve the top 6 inches of soil.
Existing lawns:<\/strong> You can add compost as topdressing<\/strong> after aerating your lawn, though the effects will be slower.<\/p>On existing lawns, \u201ccompost can be topdressed to a depth of 0.25 inches to 0.5 inches,\u201d Emerson says. Topdressing 2 or 3 times \u201cwith a high quality compost should be sufficient to improve the soil and reduce compaction \u2026 in the root zone.\u201d<\/p>

Photo Credit: claraveritas<\/a> \/ Adobe Stock Free \/ License<\/a><\/figcaption><\/figure> A thick layer of organic mulch keeps the soil in garden beds shaded, moist, and protected from extreme temperatures. Mixing organic matter into the ground also creates a haven for earthworms<\/a> and other underground life that aerate the soil.<\/p>
Best for:<\/strong> Plant beds and lawns<\/p>
Effort:<\/strong> Low<\/p>
Timeline:<\/strong> Up to an hour or more<\/p>
What you\u2019ll need: <\/strong>Here are the types of organic mulch<\/a> you can use:<\/p>
- Straw or pine needles<\/li>
- Dry, chopped leaves<\/li>
- Wood bark or wood chips<\/li>
- Grass clippings<\/li> <\/ul>
How to do it:<\/strong><\/p>
Here\u2019s how to fix compacted soil in your lawn or garden beds:<\/p>
- On garden beds,<\/strong> spread 2 to 3 inches of mulch. <\/li>
- On lawns, <\/strong>leave the grass clippings<\/a> as mulch, but make sure the layer is no more than 1 inch thick.<\/li> <\/ul>

Photo Credit: dule964<\/a> \/ Adobe Stock<\/figcaption><\/figure> Gypsum is particularly useful in the Southeast and in arid regions where clay and saline soils are common. While gypsum can\u2019t fix all types of soil, it can be applied to help fix compaction.<\/p>
Best for: <\/strong>Gypsum can alleviate compaction only in soils rich in clay or with high sodium levels. <\/p>
Effort:<\/strong> Low<\/p>
Timeline: <\/strong>30 minutes to 2 hours<\/p>
What you\u2019ll need:<\/strong><\/p>
Lawn spreader
Gypsum<\/p>How to do it: <\/strong><\/p>
Before applying gypsum to compacted soil, talk with the local Extension Office experts to ensure it\u2019s the right choice. According to experts at Louisiana State University, \u201cAdding gypsum to sandy or nonsodic soils (low in sodium) is a waste of money and natural resources and can have negative impacts on plant, soil, and ecosystem health.\u201d <\/p>
Here\u2019s how to apply gypsum to your yard:<\/p>
- Use a spreader to apply 4 to 5 pounds of gypsum per 100 square feet in your lawn.<\/li>
- Water immediately after application.<\/li> <\/ul>
6. Keep Soil Planted<\/h2>

They dig into the ground and enlarge any openings, improving the soil structure. Some stubborn taproot plants, like dandelions and plantain, can even break heavily compacted soil that you have difficulty splitting with a shovel.<\/p>
Best for:<\/strong> Plant beds or lawns<\/p>
Effort: <\/strong>Moderate<\/p>
Timeline: <\/strong>30 minutes to an hour<\/p>
What you\u2019ll need: <\/strong>Plants that can naturally break compacted soil, such as ground covers<\/a> with extensive root systems and taproots.<\/p>
Some species that can help you solve the compaction problem are:<\/p>
- Daikon radishes<\/li>
- Dandelions (trim the flowers before they go to seed to avoid spreading)<\/li>
- Alfalfa<\/li>
- Chicory<\/li>
- Fenugreek<\/li>
- Comfrey<\/li>
- Yarrow<\/li>
- Mustard<\/li> <\/ul>
Look for plants adapted to the local climate and soil. If your yard has waterlogged areas (causing compaction), plant species that can handle damp soil.<\/p>
How to do it:<\/strong> <\/p>
Install plants with extensive root systems or taproots to alleviate compaction in your soil.<\/strong><\/p>
Ground covers also improve soil health by keeping it shaded and moist. Dead leaves, stems, and roots decompose into organic matter, providing soil life with precious food.<\/p>

- Any other desired lawn care tools or products, such as a manual aerator<\/li> <\/ul>
How to do it: <\/strong><\/p>
Here are some basic lawn care practices Bowling recommends to prevent soil compaction:<\/p>
- Mowing lawns taller and more frequently to encourage deeper root growth<\/li>
- Deep, infrequent watering<\/li> <\/ul>
