The wet weather this spring and summer has produced a bumper crop of weeds in many lawns and gardens. One weed that has prospered is yellow nutsedge. It is not a grass nor a broadleaf weed, but a sedge. The grass-like leaves are light green to yellowish in color and shiny in appearance.
Yellow nutsedge is an erect plant.
The stem near ground level is triangular. The leaves come off the stem in sets of threes. Yellow nutsedge reproduces by seed and small underground tubers called nutlets. Flowers are yellowish or yellowish brown and are borne on small spikelets. Yellow nutsedge grows most rapidly during the hot summer months.
