Star Sedge

Spreading Sedge should be watered deeply and infrequently. During the summer months, it should be watered every 2 to 3 weeks, allowing the soil to dry out between watering. In the winter, water should be reduced significantly or eliminated altogether since the plant does not need additional water during this period. As a general rule, wait until the soil is dry an inch or 2 below the surface before watering. Be sure to water thoroughly until the soil is saturated.

Spreading Sedge (Carex laxiculmis var. copulata) prefers full sun to partial shade. It needs 6 to 8 hours of direct sunlight each day, ideally from morning until mid-afternoon. Too much sun can cause the foliage to yellow or even burn, so it's important to ensure the Sedge isn't too exposed during the hottest part of the day.

Pruning Spreading Sedge (Carex laxiculmis var. copulata) should be done during the spring and summer months after flowers have bloomed and any dead leaves have been removed. Pruning should not be done too aggressively as it can stress the plant and cause it to become less vigorous. Instead, light pruning should be done to maintain the shape of the plant and to encourage branching. Remove dead stems at their base with a pair of sharp shears. Also remove any thin, spindly stems that are taking up too much energy from the plant. Finally, any longer stems can be cut back to a height of 12 inches or so to give the plant a nice bushy look.
