# DIY Lawn Flattening
Bumpy lawns are caused by a number of factors. Some lawns naturally settle unevenly over time. High traffic wears down some areas while other areas remain the same height. Earthworms burrow beneath the lawn, causing bumps and hollows. Water tends to settle in the hollows, so the lawn may suffer, in spots, from excessive moisture. Flattening a residential lawn is one way to get it evened out again and should be done during the grass’s most vigorous growth and at a time when you usually fertilize.

1
Fill the valleys in the lawn with ½ inch of a mixture of equal parts of soil and sand. If you fill the hole with more soil, the grass may not be able to grow through it and you’ll end up with a dead spot.

2
Use the spade to peel back the turf over peaks. Remove the soil causing the bump and replace the turf. Step on the loosened turf so that it has good contact with the soil.

3
Fertilize the lawn following your normal procedure and apply water until the top 6 inches of soil is wet.

4
Wait one month to add another half-inch of the soil and sand filler to the low spots. Repeat this procedure once a month until the low spots are even with the surrounding lawn.
