Having an uneven lawn filled with deep bumps cannot only make it look unappealing but can make mowing a disaster. These bumps can form due to water retention issues, shade, insect damage, poor maintenance practices, and the freezing and thawing conditions of the Winter and Spring.
Regardless of the reason your lawn is bumpy, there are two do-it-yourself methods for getting an even grade. Before attempting either method you need to ensure your soil is moist. If your soil is dry, hard, and powdery it won't level the same. If your soil is soaking wet it won't level the same either. Take the time and water your lawn several days before starting your leveling project to ensure you have moist soil.
Method 1: Rake And Add Top Soil
For this method, you will need top soil, which you can get at your local hardware or gardening center. Be sure you get a high-quality top soil, as lower qualities don't tend to pack down as well. The second thing you will need for this is a steel rake for leveling. We recommend getting one that is 3 foot wide, over the standard 18 inch wide rakes. This helps save you time during the process as you can level more land at once.
Start by filling in all the holes with topsoil. You want to use the rake to provide the soil with a level surface. After you leveled off the hole you want to spray a small amount of water on the soil and let is sit for an hour or two. This time will allow the soil to better situate in the ground. For those who don't want to wait for the soil to naturally situate in the ground, they can use a tamper and stomp on the ground. Tampers are available at some gardening stores. However, they're not necessary to level the yard.
Once the topsoil has sat for a while, it's time to go back and top off the hole. Again use your rake to level the surface to make it even with the rest of the lawn. Let the topsoil sit for a week before adding grass seed.
Method 2: Rake, Sand, and Compost
Instead of using the topsoil you can opt for using a mixture of sand and compost. Some individuals prefer compost over the top soil as it's more nutrient rich. This allows for new grass to grow back quicker and healthier than with just topsoil alone. Sand is a widely popular mixture when it comes to filling in a bumpy yard because it provides an ideal consistency to ensure the other materials stay in place.
You want to mix together one part compost for two parts sand. Fill in all the low spots in your yard with the mixture and use your feet to compact the mixture into the ground. Keep compacting and adding more of the mixture until the hole is filled to the top. Use your rake to level out the ground.
Once all the holes are filled, you want to lightly water each one to ensure the mixture sits correctly. Give it a week before you add grass seed. When you do distribute your grass seed into these holes be sure to cover them up with a small amount of topsoil. This will ensure no animals get to your seeds and that water gets retained for the seeds to grow.
No matter which method you pick, be sure to do your repairs in the Spring. This will ensure your lawn retains adequate moisture to allow new grass to grow in the spots you filled. We hope that with out tips, your yard will become smooth and appealing to the eye!
