Prickly Bog Sedge

Prickly Bog Sedge requires moist soil conditions and should be kept consistently damp. Water the plant during the summer months, enough to keep the soil moist but not too wet. Ideally, water the plant once a week, but frequency of watering may vary depending on your environment, such as heat and air circulation. Water from the base of the plant but avoid getting the foliage wet. During the winter, keep the soil just barely moist. Do not overwater or allow the soil to become soggy.

Prickly Bog Sedge grows best in full sun to partial shade. It prefers direct sunlight for 4-6 hours each day and will tolerate some shade. To get the best growth, it is best to keep its location consistent each day.

Prickly Bog Sedge (Carex atlantica) should be pruned annually for best results. Pruning should begin in late winter or early spring when the plant is in its dormant stage. Cut back stems to the base of the plant by trimming them with hand pruners or shears. This will encourage new growth that will bring a denser, more vigorous plant. After the dormant pruning, additional pruning may be necessary throughout the growing season to help shape and groom the foliage. Remove spent flowers and seed heads to encourage regrowth and help maintain an attractive form. Removing any dead, damaged, or diseased foliage should also be done to promote healthy growth.
