Bearded Iris hybrids

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 
Zone 5 Ontario

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.
