Time to divide bearded iris

If your iris are crowded, divide them now. Dig up clumps, cut apart rhizones into divisions with roots and a fan of leaves. Dispose of any damaged or diseased parts. Trim the leaves as you wish for tidiness. Replant about 18" apart at a shallow depth - the same depth as before (unless your clumps were so crowded that they were out of the ground). Water well.
