I have a small patch of my lawn that is pretty much destroyed and I will have to re-do in September. I should have done it this spring but didn't have the time and tried to do it the easy way.

Last year we had some trees removed, and where the guys put their tree removal equipment basically killed that part of my lawn. Now this fall I have these thing popping up all over and I can't get rid of them. I pull them out but it seems the next day there are more. I've put down weed and feed recently but it didn't do a thing.

Any ideas what this is?
