Hudson bay sedge occurs naturally in habitats like forest understories and rocky areas, where it grows in natural shade. It prefers partial sun but can tolerate full sun or full shade, reflecting its versatility and hardiness.

Hudson Bay sedge does best in cold areas and at high altitudes. It prefers cool temperatures, good airflow, and a moist environment. In summer, steps should be taken to keep it cool because it is highly sensitive to heat and can easily die. Dry conditions can also be damaging. In winter, no special cold protection is necessary, but maintaining soil moisture is important.

Hudson bay sedge needs extra nutrients to encourage healthy new growth. In spring, placing compost around the base of the plant will effectively supply the required nourishment. Fertilizing supports vigorous growth and helps the plant resist diseases and pests.
