Spread 2-inches of mulch over the iris bed after trimming, if these are first year plants or if your area experience winter freezing. Irises don't require water or fertilization after you cut them back because the rhizomes go dormant until spring.
Place the rhizome firmly on top of the mound and let the roots fall down the mound. Cover the roots with soil so the rhizome is just slightly exposed. Do not plant the rhizome too deep or it may rot. Generally iris are planted 18-24 inches apart in groups of three to seven sections of one variety. Usually the rhizomes are planted so the leaf fans face in one direction.
