Hey all, I seeded a yard with buffalo grass this past May. It's looking really good right now..filled in very well in a short time. It had a lot of nutsedge, crabgrass, smartweed, and other broadleaf weeds in it, so I spayed it with Bayer Advanced Weed Killer for Lawns. It's working really well so far, killing all but the buffalo grass. I'm worried about weeds next spring though since some of the weeds have already gone to seed. What pre-emergent herbicide should I apply? Anyone have experience using corn gluten as a pre-emergent?
