Caring for Feather Reed Grass:
The cultivated varieties tend to be sterile and set no seeds that could cause them to spread aggressively. They are also clump forming, rather than spreading by rhizomes. They will eventually need to be divided, generally every 3-5 years, to prevent them from dying out in the center. Divide in the fall or early spring. Gardeners in cold climates will have better luck dividing in the early spring.
