In cold climates, clumps die to the ground in winter. Plants will also naturalize by self-seeding. Soft rush may be grown in tubs or containers sunk in the mud to control unwanted rhizome spread. Clumps are often slow to establish, but once established will spread by creeping rhizomes. Warm season grasses will tend to bloom in mid to late summer.ĭespite a preference for abundant moisture, soft rush will perform surprisingly well in average garden soils as long as they receive consistent irrigation.

To make the recipe work using larger plants, you will need to choose a pot that is larger than our suggested size or use fewer plants of each variety in the recipe.
