Yellow Nutsedge
Nutsedge
Yellow (Cyperus esculentus)
Purple (Cyperus rotundus)
Sedges have
triangular stems with waxy grass-like leaves which alternate. Sedges
are not grass plants, but seedlings may be mistaken for grass. The
leaves on both sedges
are waxy and have an up right growth habit and a prominent midrib.
Both sedges have underground root systems containing rhizomes and
underground tubers which accomplish most of the reproduction. On yellow
nutsedge, the tubers (nutlets) form at the end of whitish rhizomes.
Purple nutsedge forms chains of tubers along brownish rhizomes.
Improve drainage
through core aeration and lightening the soil. Keep turfgrass sites free
from stress and vigorously competitive with sedges. Keep mowing heights
as low as possible in spring and early summer when sedges are most actively
growing. Fertilize cool-season grasses in the fall after frost.
