Watch as Better Homes and Gardens shows you how to divide bearded iris plants! Late summer or early fall are the best times for dividing irises. Dig up and divide irises when a clump gets crowded every three to five years. With a garden fork, lift a section of iris rhizomes out of the ground. Separate individual iris rhizomes with a garden knife. Keep only the healthy ones. Cut the healthy rhizome leaves back to four to six inches. To plant irises, dig a shallow hole, then set the rhizome with the leaf fan pointing up. Cover the iris rhizome in soil. Keep these gardening tips in mind when dividing iris plants in your home garden!
