I have some patchy weird grass or weeds growing on my lawn. You can see in a few places in the images below:
Picture 3: you can see it a bit better here. I think my desirable lawn here is a bit of fine fescue and maybe some KBG (the slightly discolored + green blades at the bottom of the picture?). Does that seem right? What about that nasty ugly clump near the top of the picture? Broadleaf weed or undesirable grass? Is it the same as pictures 1 + 2? I think so. How do I get rid of these?
