After reading this article I'm going to make a better effort at dividing my beardeds right after bloom.

Bud Development in Iris (AIS Bulletin June 1923)
J. Marion Shull

.......bulbs such as Narcissus, Hyacinths and Tulips have their flower buds already formed............waiting only the right conditions.............but it may not be so well known that iris also takes thought of the morrow and provides for the next season's bloom before it goes to rest. ...........may also suggest some difference in our treatment of the Iris in after-summer if we would have abundant bloom the following spring.
.................... may not be devoid of practical bearing if we will bear in mind that August, September and October are the critical months so far as bud formation is concerned: that the growing conditions of this period will determine whether our clumps will be graced with many or few flower stems the following spring. It would certainly indicate that the best time for resetting is very shortly after blooming, or, failing that, not until after the buds have had time to form, with perhaps just time left for roots to take hold of the soil for the winter.

RE: timing on dividing beardeds

Hmmm, this was written in 1923? Maybe this notion has been disproven since then. In the spirit of scientific experimentation, however, I think I'll try to transplant and divide half of my plants just after flowering to see what happens. I'll report back on results.
