How can I successfully transplant iris flowers to a new location?

To successfully transplant iris flowers to a new location, dig up the iris rhizomes in the fall after they have finished blooming. Choose a sunny spot with well-drained soil for the new location. Trim the leaves to about 6 inches and replant the rhizomes about 12 inches apart, making sure the roots are spread out and covered with soil. Water the transplanted irises well and continue to water regularly until they are established in their new location.
