Hi Margaret,
When to divide seems to be highly dependent on the cultivar. While for cold
zones like ours, many people favour spring planting, some cultivars really
sulk when divided in the spring. However these seem to be in the minority.
Planting in the spring seems to give the plants a better chance to
acclimatise. But if you are buying from someone in your own area, I suspect
that the difference in performance may not be noticeable.
I prefer to divide soon after bloom. But I have been known to dig up clumps
just as the leaves emerge.

Boy did I learn a lot reading the "what are appropriate divisions"
notes! Thank you everyone. It was especially interesting because I've
dug and divided some this year that had been neglected for years and
many were "stacked" like root sandwiches and I didn't know how to treat
them. My usual way of "dividing" is to do the pie wedge routine and let
the sides move into the newly enriched soil. What I take out is often a
root sandwich mess, and always the little (I've never seen a "large"
siberian rhizome, what constitutes "large?"), rhizomes are connected to
each other.
This fall one of the "pied" clumps appeared to be dying, or one half of
it did and I chalked it up to the drought. When I dug to see what I
could save I discovered a large rock that was working its way up from
who knows where was about 2" below the dying section. I dug it out and
enriched the soil and replanted what seemed viable and have crossed my
fingers and hope I wasn't too late in the season.
Someone in the "what are good commercial divisions" notes mentioned
dividing in July. Tracy DiSabato-Aust, the Well Tended Perennial Garden
author (great book if you haven't seen it), says she divides siberians
whenever it suits her! I've been told, and have experienced, that
spring is best in New England, but many of you clearly do it in summer
or fall, even late fall. So, in addition to what makes a good
commercial division/shipment, I'd like to know WHEN is a good commercial
division?
And what does one do with the root "sandwiches"?
