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.
Unlike many other perennials, iris rarely require a serious trimming. Pruning back the leaves before transplanting is a necessity to avoid damaging them. Minor trimming, especially before the winter months, also improves the look of the plant and helps prevent diseases from affecting your iris plants.
