I have at least a dozen areas in my lawn that have these longer patches of grass. It's clearly a different species than the rest of my lawn, but I don't know why it keeps popping up. It grows 2x/3x faster than the rest of my lawn, so it makes the lawn look sloppy within less than a week after mowing. (I live in Ohio)

I had weed/crabgrass control applied to my lawn earlier in the year -- should this have been killed by a weed killer? Any other thoughts on how to quickly eliminate it?enter image description here

    I believe that is a sedge, not actually grass, so grass killers do not work on it.

  • The product listed is not listed as effective on nutsedge, according to Clemson University. See here for more details: hgic.clemson.edu/factsheet/nutsedge
