I'll admit, I'm not that great at grass identification. I have a few pictures of some grass that is growing in bunches on a customers property. It will not cut. My blades are changed everyday and the few spots where this stuff is growing give the appearance that it was mowed with a dull blade. I can't figure out what it is. I don't know if the pictures will do any justice, but I figured I would try here before I take it to the county extension office or Lesco. Anyone have any ideas.
