Best Answer: Cut off dead blossoms and dead bloom stalks when the iris has stopped blossoming, but don't cut back the leaves until they begin to turn brown in the fall. The leaves are needed to produce next year's blooms. When you do cut, leave a fan shape about six inches long.
Iris should be divided in the late summer after they have stored energy in their rhizomes all summer. If you wait too long into the fall to replant the rhizomes, the roots may not have enough time to establish before the ground freezes and the plants will be subject to frost heaving.
