This looks to be in the sedge family either green or false green Kyllinga. Look to see if the stem is triangular in shape, that is a characteristic of sedges. Sedges and Kyllinga tend to grow in wet soil; Kyllinga can grow under regular mowing. Hand weeding will work but you must remove all underground tubers and rhizomes. Chemical control can include chemicals with active ingredients of Imazaquin, Flazasulfuron, or Trifloxysulfuron. If you have any further questions you can contact your local Cooperative Extension Service.
