I went to mow the yard today and found 1-2 inch plugs of grass pulled out of the ground all over the place. It looks more like the result of digging than a deliberate pulling out.
What could be doing this, and what can I do about it?
I've had this happen many times over the years. In my case, it was flocks of crows tearing up the lawn looking for grubs. It's almost comical how they rip out a piece of sod and toss it over their shoulder.
On the other hand, the grubs can't be good either. You might want to try some grub killer.
