Is it a true bump (a hill of dirt) or a depression (a sunken pit)? Walk around barefoot. You’ll feel the problem spots immediately. Mark them with a garden flag or a stick—anything visible from a distance.
Don’t just guess. Get down on your hands and knees. Look for thatch—that matted layer of dead grass and roots. Thatch can create a spongy, uneven surface all by itself. Gross, but fixable!
