My neighbor got this off Facebook marketplace. He shoved it in a corner. Behind the fence is my vegetable garden. As you can see it’s messy, has no edging around it and honestly have no idea why someone would get a dress grass and above it in such an inconspicuous spot. It’s popping up 2 feet away in my vegetable garden now and it doesn’t come out easy. What is it?? I have a big bluestem (maybe holy smokes ) that I want to move and may ask if I can take his grass out and replace it with my bluestem.
