Rigid Sedge

Carex tetanica

Rigid Sedge, or Carex tetanica, is a small clumping perennial plant native to North America. It grows in moist, open environments, often along the edges of streams or lakes. Its two to four-inch narrow leaves have a bristle-like feel, and its stiff, round stems typically reach up to three feet in height. Its female and male flowers appear in separate clusters at the top of the plant. Rigid Sedge requires full sunlight and moist, well-drained soil and will tolerate seasonal flooding. It is a great addition to any garden as it adds texture and interest while also providing habitat for wildlife.

watering

Rigid Sedge should be watered about once a week during the growing season. The best time to water is in the morning, allowing the sun to dry the plant and keep its foliage from getting too wet. During dry weather, Rigid Sedge may require extra water, and during cold winter months, it should be watered only when the soil is completely dry. It's also recommended to avoid overhead watering and to apply water at the plant’s base to keep foliage dry. When watering, use a slow and steady stream of lukewarm water to ensure its roots are hydrated evenly.

sunlight

Rigid Sedge (Carex tetanica) is an ornamental grass that prefers full sun exposure. Though it can tolerate some shade, it grows best in an area where it receives at least 4 hours of direct sunlight per day. During the height of summer, the ideal amount of sun for Rigid Sedge is around 6 to 8 hours of bright light per day. In the winter, the plant should receive 3 to 4 hours of sunlight per day. Prolonged exposure to scorching sun can cause the plant to be stressed, resulting in burned or browning leaves. For this reason, it is best to position the plant in part shade with some protection from strong, mid-day sun.

pruning

Rigid Sedge (Carex tetanica) should be pruned in late spring when the new growth has developed. Prune the old foliage back to the ground and remove any dead or damaged tips. This species should also be pruned back during the summer to encourage bushier growth. When doing pruning at this time, it is important to remove the top growth only, not the flowering stems. This species should not receive heavy pruning as it forms a very dense habit. Pruning should be minimal to encourage the natural openness of the foliage.
