An annual weed in cooler climates, or sometimes a perennial in warmer areas. Reproduction is from seeds, and plants also spread by underground roots. This is a weed of many habitats, including turf, landscape, and roadsides.
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.
