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.
Although the iris rhizome is planted in a shallow hole, the soil should be loosened to a depth of 10 inches to allow for optimum root growth. Place the rhizome so that it sits barely under the soil, firming the soil around it, and then water it in. Potted iris can be planted in the spring using care to plant at the same soil level as in the pot. Containerized iris are often available in spring at local garden centers.
