Clay Soil. If you have clay-heavy soil and live in an area where the soil freezes in winter, you may see new bumps and bulges in your lawn during the spring thaw. It’s the clay soil causing heaving and buckling, which results from uneven thawing.

Hereof, how do you flatten an uneven lawn?
The lazy way is to just fill in the lumps, just like that. Get some soil from elsewhere in the garden, a cane to check the levels, and then fill in the gaps. Leave it a few days then top it up when it sinks. You could then sow with fresh seed, or you could just let the grass grow up and through.
