Some type of grassy weed. Was at a few homes where I have put down barricade and dimension. Not at edges either but in the middle. One house not real bad, the other, all over the damn place in the middle. I'm thinking there is no way that much broke through the barrier. Maybe a perennial grass that had already set its seed last year or something. The 2 yards it was at are 2 properties I just picked up at the end of the season last year. I hope the Q4 plus I hit it with knocks it out. What is it? Seems the leaf margins are wavy on all of the clumps I saw. Didn't notice any hairs.
