Merten's Sedge

Merten's Sedge should be watered once or twice a week, depending on the season and soil type. During the growing season, when the plant is actively growing, it should be watered deeply and thoroughly. In order to ensure an adequate water supply, water until the soil is moist but not soggy. The amount of water depends on the size of the pot and the type of soil. If the soil is very sandy, more water may be needed. During the summer months, it should receive an inch of water per week. During the winter and in very hot climates, water less frequently to prevent over-exposure.

Merten's Sedge prefers a moderate amount of direct sunlight, but does not require it to thrive. It can tolerate full sun or partial shade, but does need at least 6 to 8 hours of sunlight each day. It prefers sunny locations in moist soils in full sun or partial shade, but can also tolerate dry soils and even flooding. The best time of day for Merten's Sedge to receive sunlight is during the morning hours, since the sun is low in the sky and not as intense. Additionally, afternoon sunlight may be too hot and may cause the plant to dry out too quickly.

Merten's sedge (Carex mertensii) is a low-growing, evergreen perennial best known for its soft, tufted foliage. It prefers part sun to shade and moist to wet soils and is 1 of the few sedges that will grow in boggy soil. Pruning of Merten's sedge can be done to remove dead or brown foliage. Pruning should be done moderately so as to not damage the plant. It is best to do the pruning early in the spring or late in the fall when the plant is dormant. Mild thinning or shearing is all that is required to keep it looking its best.
