Re: CULT: digging/dividing times


With bloom season nearing its end (the last 2 TBs, COME WHAT MAY and CAROLINA HONEY, will have folded by tomorrow morning, only a couple Siberians have a flower or 2 to bloom, and just spurias have profuse numbers of flowers remaining) my thoughts turn to the question of digging/dividing/replanting.  My basic question is, "What's really the optimum time, relative to bloom season, for this to take place?"  Under this basic inquiry, a couple subquestions.  (1) I used to do this for my bearded iris as soon as I could find the time after bloom season.  Then I read WORLD OF IRIS, and saw that no less an authority than Ben Hager advised 6-8 weeks after floom as optimum.  Ever since then I have been trying to follow, more or less, that advice of an obvious expert, but I can't notice any better or less success than my old way of the unlearned.   (2)Should i. brevicaulis be treated the same as the bearded iris in this regard?  If not, when should I dig them?  I have never dug this be!
 fore, having had it only a few years, but now it's clearly time.  (3)What about spuria?  I haven't dug these before, either, and the signals I have had are as mixed as those coming from my bearded experiences.  What's optimum time there?
    I know the answer has to be in relationship to bloom season, whatever that may be for you, because we live in such different climatic zones, but I'd be very interested in any expertise/experience you can give.
