Sun Sedge

Coastal Sand Sedge requires very little water, and should be watered only when the soil is completely dry. It's important to check the soil before watering to prevent overwatering, which can cause root rot. During the growing season, water once every 7 to 10 days and during the winter only water as needed. Apply water slowly and deeply so it can penetrate the soil. For younger plants, water every 3 to 5 days until established.

Coastal Sand Sedge (Carex incurviformis) is a moderately shade-tolerant species that grows best when exposed to light levels between 30 and 50 percent. This semi-shade condition provides the plant with enough sunshine to adequately support growth, while avoiding the harsh conditions of full sun. During the spring and summer months, Coastal Sand Sedge should receive 8 to 10 hours of direct sunlight each day, spread out evenly over the day. In the autumn and winter months, 4 to 6 hours of direct sunlight per day is sufficient.

Coastal Sand Sedge should be pruned in March or early April each year. Pruning should be light, and only remove dead stems, as the plant is a perennial and its growth habit is clumping. Pruning should not exceed 10-20% of the plant, and any dead stems should be cut down close to the ground. When finished pruning, the plant will have a neat, good-looking shape, and it will promote vigorous growth and flowering in the summer and spring.
