Cylindric sedge is an upright perennial weed that can reach heights of 20". It is a very common weed in sandy and moist habitats. The seedhead is comprised of several spikelets. Each spikelet consists of a long stalk with an oblong cluster of seeds perched on the end. Cylindric sedge and globe sedge seedheads are very similar in appearance. However, globe sedge seedheads are round, whereas cylindric sedge seedheads are oblong.
Sedges are weeds that resemble grasses but unlike grasses, sedges have three-sided or triangular stems. It is important to properly distinguish sedges from grasses because management is totally different. As a general rule, sedges are more of a problem in warmer climates than cooler climates. Proper identification and an understanding of the biology of sedges are necessary for effective management. Sedges are plants that thrive in wet or poorly drained soils but can survive in areas that are not wet. Because of frequent irrigation in highly maintained turf, sedges often thrive in the turfgrass environment. Sedges often become established in wet areas and spread to other areas that are not poorly drained or wet areas. Therefore, it is important to recognize areas where sedges can become established and prevent spread of these sedge species to other areas of the golf course or landscape.
