Pebble Sized Mounds of Dirt
Question: I've recently noticed that I have all these tiny little pebble sized mounds of dirt all over my lawn that kind of resemble BB's. I don't see any critters or insects, is this harmful?
NICK: Let's not make a molehill out of something that's much smaller. These little piles of dirt that you're talking about are created by worms. They're usually only about a quarter to a half dollar in diameter, and never much more than a half inch tall. What's happening here is that your soil is too saturated and the worms are digging themselves out, trying to get a breath of fresh air for lack of better words. So what you need to do is to dial down on your irrigation, so that you don't smother them.
