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.
This will make it easier to see when you are breaking the clumps apart. The next step in dividing iris plants is to divide the iris rhizomes. Each iris rhizome should be divided into pieces that are 3 to 4 inches long and have at least one fan of leaves on the rhizome. Do not remove the roots from the rhizomes.he first sign that your iris need divided will be decreased blooming. Overcrowded iris rhizomes will produce fewer flowers than uncrowded iris rhizomes. If you have noticed that your iris are blooming less than they have, you may need to transplant the iris in your garden.
