Sedges generally appear in water soaked or slow draining areas in turf. They are hard to get rid of because they produce underground nutlets that produce new sedge plants. When you try to hand pull the sedges the plant pulls out of the ground, but leaves the underground nutlet to form a new sedge.

Sedge control involves management practices that encourage the most favorable conditions for the desired plant species (your grass) that will make it the most competitive it can be. Maintaining a dense stand of turf that is well drained and not overwatered will reduce sedge problems. The existence of sedges in a stand of turfgrass indicates a lack of turf health and vigor, the existence of voids, and the indication that too much water is present.
