Dividing iris requires a few simple steps:
1. Select a large clump in which there is little vegetative growth at the center of the plant. Use a pitchfork or broadfork if you have one, as you are less likely to damage the plant by slicing through the rhizomes. Dig down several inches and lift the entire plant (or as much as you can get at once) out of the ground.

4. Plant the rhizomes in well-worked garden soil. Dig a hole and spread the roots well within it, then back-fill the hole, covering the rhizomes about halfway up with soil (about half the rhizome should be sitting on the surface of the soil when you are done). Water in well to help the soil settle, then add more soil and firm in well if necessary. Space the rhizome pieces at least 6 inches apart.
|Whether you are planting your rhizomes in a pot or in soil, water them well.|
