Easily grown in moist to wet soils, including standing water to 4′ deep, in full sun locations. Tolerates light shade, but best in full sun. Notwithstanding its preference for abundant moisture, soft rush will perform surprisingly well in average garden soils as long as they receive consistent irrigation. Clumps are often slow to establish, but once established will spread by creeping rhizomes. Soft rush may be grown in tubs or containers sunk in the mud to control unwanted rhizome spread. Plants will also naturalize by self-seeding.
