CareAnnual maintenance consists of cutting the old growth down in early spring before new growth starts. Reed grass grows out from the center, and after a few years, you may discover a hole-in-the-doughnut effect. When this happens, dig the plant up and divide it. Preferred time for dividing is in spring.
