Bearded Iris hybrids
B Spencer (Mon, 10 Nov 2014 05:21:45 PST)

The rule is to divide and replant after flowering. I have had some bearded
irises in various parts of my zone 5 Great Lakes region with hot humid
summers and alternately periods of drought and excessive wetness in summer
for 42 years without any coddling. Tough little plants. There were
instances when rhizomes made it through the winter on top of the ground
where I left some and forgot about them. The only things that would do them
in would be EXCESSIVE moisture in winter and iris borers. If you plant in
slightly raised beds, you can get rid of of the moisture problem. Borers are
a problem nowadays since all systemic insecticides have been banned by our
leftist government in Ontario for a home gardener ( tones and tones of the
same stuff dumped on our farm fields is OK. How is that for hypocrisy?)
They need to be planted very shallow with some of the rhizome exposed.
That said, they are very forgiving plants. As the other members mentioned,
even the dried up ones from the box store or the ones that mail order
nurseries insist on sending at the end of September will make it with some
more care, perhaps planted in pots for the first winter and kept in a cold
greenhouse?

Brian,

Where I live in summer dry southern Oregon I have had the most success
making divisions in late summer before the rains come and initiate new
growth. Not sure when that would be for you.
