How To Divide Iris: A Step By Step With Photos

How long has it been since you last divided your irises? If you don’t remember or worse, have never divided them since initially planting, then odds are it’s time. Other indicators that you may need to divide your irises include few or no blooms, and a large mass of rhizomes that are tightly grown together with little or no spacing. The general rule of thumb is to divide every three to four years according to the American Iris Society.
