If your yard stays wet for days after rain, the lawn can suffocate due to lack of oxygen, inhibiting its growth. The excess water can also lead to fungal diseases while making it tough for the lawn to absorb vital nutrients, further preventing healthy growth.

Lawns that are consistently squishy to walk on or have extensive puddling that refuses to go away are likely waterlogged. This condition is a symptom of poor drainage caused by factors such as heavy clay soil, flat terrain, low spots on the lawn, and heavy foot traffic. These solutions will help you understand how to fix a soggy yard.

1. Dry It Out

It’s impossible to work with mud, so before a water-damaged lawn can be repaired, the excess water needs to evaporate. If dry, sunny weather is in the forecast but puddles persist on the lawn, use a broom to sweep them away. When the soil finally dries to the point of being only moist instead of squishy and saturated, you can get to work. In the meantime, keep people and pets off the affected area as much as possible.

2. Aerate the Lawn

Soil compaction is the most common reason that lawns become waterlogged. Lack of space between soil particles means air and water cannot pass through, so water remains on the surface, saturating the ground and often killing the grass. Rent or purchase a hollow-tined core aerator to aerate the lawn.

The best machines to repair this kind of damage feature long, hollow tines, spaced 6 or fewer inches apart, and a heavy body that pushes the tines deep into the soil. The soil must be moist but not soggy for the aerator tines to sink at least 1 inch into it. As the machine rolls across the lawn, it leaves the plugs on the surface. Leave them there, and let the rain dissolve them back into the lawn.

3. Top-Dress With Compost and Sand

Poor soil structure goes hand in hand with low organic content and a dearth of biological activity. After aerating, apply compost either alone or mixed in a 1-to-1 ratio with horticultural sand. Both compost and sand work their way into the voids created by aeration to help maintain an open soil structure. Beneficial microbes in the compost, and the earthworms they attract, continue to loosen the soil particles, improving drainage and promoting healthy plant growth.

4. Grow Deeper Roots

As soil becomes compacted, plant roots die off in the compacted zone. As roots are excluded, the compaction issue becomes worse and soil is more likely to become waterlogged. To eliminate the problem, make deep root development a priority.

After aerating and top-dressing with high-quality compost, overseed to address dead zones that have no grass coverage. Keep the area evenly moist during germination. Afterward, develop a routine of deep, infrequent irrigation, rather than daily light watering.

5. Install a French Drain

Not every wet zone is caused by soil compaction. Low-lying or flat areas of a lawn may be subject to pooling or groundwater seepage because of the lack of slope. In these instances, an underground drainage system may help dry out the area. The fix may be as simple as installing a French drain, to move the water away from the problem area. Installing a French drain requires a nearby sloped area that is lower than the problem site, so the water has a place to flow.

6. Create a Rain Garden

If the waterlogging is the result of excessive runoff onto a relatively flat area, installing a rain garden could help alleviate the issue. A rain garden is essentially a small, boggy plot. Create a depression with a berm on the low side to intentionally collect rainwater. Plant the garden with an assortment of attractive water-loving, rain garden plants, such as sedges, cardinal flower, bluestar, swamp hibiscus, and many others. A rain garden in the right location reduces flooding, filters pollutants from the water, and provides habitat for birds and pollinators.

7. Redirect Downspouts

Poorly designed or directed gutter downspouts can lead to a waterlogged lawn. If your house or garage sends excessive amounts of runoff to the yard, you can use 4-inch PVC pipes from the hardware store to move the water elsewhere. Dig a shallow trench from the outflow of the downspout to the location where the water needs to go. Be sure to slope the trench away from the house.

8. Install a Dry Creek Bed

Sometimes a simple ditch is all you need to redirect the water, but for greater curb appeal and lower maintenance, you can turn that ditch into a dry creek bed. Start by creating a channel that will carry the water downhill and away from the affected area. Then, use landscape fabric and rocks of assorted sizes to armor the sides of the channel. Finish it off by planting perennials and shrubs to soften the edges and give it a natural look.

9. Regrade the Lawn

Hiring a professional with expensive equipment to reshape the yard sounds like a drastic measure, and it is. But if water consistently pools beside the house or across pavement, or if other treatments just haven’t worked, regrading may be the best option. The contractor surveys the property to uncover the source of the problem and calculate the grade line. Then he uses specialized equipment to raise the low spots, lower the high spots, and ensure a positive flow in the right direction.

10. Install a Sump Pump

If your soggy grass problem is severe, a sump pump might be a worthy investment. Sump pumps can draw water away from the lawn and pump it into a designated area, helping to keep your lawn dry. They’re commonly used in low-lying areas that are prone to flooding, and they’re more effective at removing large amounts of water than French drains.

11. Add Some Gypsum

Gypsum is a mineral that you can add to your soil to improve drainage. The mineral helps break up and loosen compacted soil, allowing the soil to better absorb water so that it doesn’t pool on top of your lawn. Application recommendations vary by manufacturer, but it typically involves spreading the gypsum across the waterlogged areas and watering it into the soil.

12. Create Raised Beds

If waterlogging only occurs on certain areas of your lawn, you can often fix it by creating raised garden beds. They’re fairly straightforward to make. All you need to do is add an elevated mound of well-draining soil to the affected area and plant moisture-tolerant vegetation. The extra elevation that the mound creates will help drain and soak up excess water in the yard, preventing it from pooling.
