Nutsedge is a warm-season, perennial plant, that is part of the sedge family. Nutsedge superficially resembles a type of grass, but is quite different. Nutsedge is green and stands straight up just like grass; a closer look, however, will reveal many unique characteristics. Nutsedge has thick, stiff leaves with hollow, round stems. They can quickly spread and form dense colonies. They thrive in wet soil and, once sprouted, can also survive in dry conditions. They are listed as one of the most problematic weeds in agriculture with potential to greatly reduce crop yields. When looking from the cross-section, they have a slightly triangular stem base with “v” shaped leaves. Nutsedge is produced from seed, or spread by underground stems, or rhizomes, that will form new plants. They spread underground through creeping tubers that move horizontally and develop sprouts.
Nutsedge can spread rapidly where there is little or no competition. If you notice plants, the only way to properly remove them is to completely dig them out or employ a selective herbicide. Because of their underground sprout development, merely pulling them out will not stop further sprouts; it will only delay their onset.

Nutsedge typically thrives in damp regions or areas with improper irrigation. Controlling nutsedge in the long term, relies on remedying these problems. Improper irrigation can be a result leaking sprinkler systems or poor drainage. Aeration and over-seeding can greatly help reduce soil moisture and provide a healthy density of grass. A thick lawn is always your best initial defense against weed or unwanted plant development.
