Place your long board across the area and check for gaps beneath it. If you see daylight, add more soil. If the board wobbles, tamp down the high spots. Patience is your best friend here—wait a week after filling, let rain settle the soil, then re-check.
Every lawn settles over time. You might need a touch-up every spring. Think of it like fluffing a pillow—it’s maintenance, not a total redo.
