Can you put top soil on top of grass seed?

Yes, you can put topsoil on top of grass seed, which can help improve soil quality and provide a better environment for seed germination. A thin layer of topsoil can protect the seeds from birds and erosion while retaining moisture. However, avoid using too thick of a layer, as it may suffocate the seeds and hinder their growth. It's best to lightly mix the seeds into the topsoil for optimal results.
