|Late summer (August) is usually the best time to dig and divide iris. Dig up the clumps with a garden spade and separate the rhizomes. Then break away the ends of the rhizome and replant them, discarding the old center of the rhizome. Before replanting you can cut the fan of foliage down to 4" or more (for ease in handling). Dig a shallow trench and lay each rhizome in the trench, spaced about 6" apart, with the ends pointing in the direction you want new growth. Cover with an inch or two of soil and water the bed well. Next spring your renovated iris bed should bloom with great enthusiasm!
