Yellow nutsedge can be a highly competitive weed smothering crop plants like
tobacco. Yellow nutsedge
produces rhizomes and tubers that may be spread by cultivation. Yellow nutsedge may be called swamp
grass or nut grass locally, but is not a grass. It does occur more commonly in damp or occasionally wet
areas, but can occur in well drained silty or sandy soils. Rolling the stem between index and thumb will
reveal the triangular stem. Grass specific herbicides will not control yellow nutsedge.
