Pest Details

Long's Sedge
Long's Sedge


Native to North America, where it is found throughout the states east of the Mississippi River and west to Texas and Oklahoma. It also is found in Hawaii.


A perennial reproducing from seeds and spreading with rhizomes. Common along moist roadsides and disturbed areas.


Mature plants may form thick clumps of numerous stems, which are very long and thin, terminating with the flower spikes. Leaves are sparse, and arise from the base and the lower stems, and they are flat but weak, and tend to droop. The oval flower spikes may occur singly or as several along the end of the stem. They are a compact spike of many dozen flowers and have a covering of hairs that give them a soft appearance and texture.

Characteristicts Important to Control:

Control of excessive moisture in turf will help to discourage the growth of most sedges, including the various Kyllinga species. For sedges that reproduce only from seeds control with pre-emergent herbicides can be effective. Post-emergence control in turf will require a selective herbicide which targets the sedges specifically. In non-turf settings a systemic, non-selective herbicide will be effective.
