The Q&A Archives: Dirt Bumps In Lawn

Question: There are dirt mounds and it feels bumpy when you walk on the lawn but you cannot see the bumps. This is the second spring in a row that this as happened. The size of the dirt mounds are around 1 to 2 inches in size. What could I do? Don't want any dangerous chemical because of kids.

Answer: It sounds like earthworms are living in your soil. The presence of earthworms is a good sign--it means that your soil is rich and healthy. The worms help aerate the soil, making it a better environment for grass roots.

Earthworms dislike compacted and dry soil. (Then again, so does grass...) If you've been watering your grass frequently, you might cut back. Water deeply once in a while, instead of frequent shallow watering.

Other than you know of anyone who likes to fish? Maybe you could find a local child who would love to come collect them after a rain...after all, most fisherman have to buy their nightcrawlers!
