Adding Soil Over Grass and Sod
If you put soil on top of grass, the grass may eventually die due to a lack of access to sunlight, nutrients, and water. The soil will suffocate the grass, becoming heavily compacted and blocking vital components for the grass’s survival.
Considerations for Adding Topsoil
- After spreading the topsoil, use a lawn roller to pack it down and create a level surface.
- Apply grass seed over the topsoil at approximately 2 to 3 pounds per 1,000 square feet.
- Water the newly seeded area frequently for the first few weeks until the grass becomes established.
Revitalizing Lawn with Topsoil and Reseeding
Yes, you can put topsoil over an existing grass lawn and reseed it through overseeding to improve the quality of your lawn. It’s important to mow the grass short and remove debris before adding topsoil.
If the topsoil has not been sterilized, it can introduce weeds and diseases into the soil. A thin layer of topsoil can help thicken the grass, make it greener, and provide necessary nutrients. Avoid adding excessive topsoil to prevent light and air blockage from reaching the grass roots.
