Choose firm rhizomes that have both roots and a leaf fan. Discard (and do not compost) rhizomes that seem squishy or limp, as they may be rotten or diseased. This is a good time to remove spent foliage and larger, older leaves that may cause your plant to tip over before it establishes new roots. Do leave most of the foliage. You can break off the rhizomes by hand, or use a sharp knife to make the cut cleaner.
Bearded irises appreciate a limed soil, so provide this if necessary. [5] X Research source
