leveling a bumpy yard
My yard is undergoing a transformation. I have begun an organic routine. It's been 2 months and I can already see a huge difference in the quality of the soil. I used to not be able to push a knife more than 1" into the soil. Now, I can push my finger in that far and a bamboo stake in about 3 inches. The problem I have is that my yard resembles a 4x4 test track. There are divots and small bumps everywhere. My 6 year old has had 2 sprained ankles and I have twisted mine mowing the lawn.
Is there a way to level out this lawn without bringing in yards of topsoil and shoveling it all over?
