Marsh Straw Sedge

Marsh Straw Sedge (Carex hormathodes) likes moist soil and needs to be watered regularly. During the growing season, the soil should remain consistently moist. Water no more than when the top 2 to 3 inches of soil begins to dry out. In hotter, dryer weather, the plant will appreciate being watered every other day or more. In cooler weather, once or twice every week should be adequate. Water deeply, so the soil can absorb enough moisture to keep the plants hydrated. To minimize potential disease problems, water in the morning so that the foliage can dry off before nightfall. In winter, when the plant is dormant, it can tolerate brief dry periods, but an occasional deep soaking is beneficial.

Marsh Straw Sedge (Carex hormathodes) grows in open wetland areas that experience full sun. The plant can tolerate partial shade, but for optimal growth and health it should receive 6 to 8 hours of direct sunlight each day. It is most likely to thrive in areas that have relatively long growing seasons and receive ample amounts of sunshine during the summer and early fall. During the spring and winter, the plant should still receive some direct sunlight, but it may require less intense rays and shorter periods of exposure.

Marsh Straw Sedge (Carex hormathodes) should be pruned just once a year in late spring or early summer when the weather is warm and the plant is actively growing. Pruning should be light and should only include removal of dead and damaged portions of the plant. It is best to avoid cutting too far into the crown or healthy foliage, as this may leave the plant vulnerable to disease or insect damage. Care should also be taken to avoid cutting off any flower spikes, as they are important for seed production.
