This stuff is taking over my yard as well as my neighbors yard. We didn't have this last year but what we did have is "normal crabgrass" problems. I'm using Drive XLR8 to kill crabgrass but this weed/grass laughs XLR8 off.
One lawn care professional said it's Timothy grass but looking it up on the net it's totally different. Any help with a description and treatment I'd appreciate.
