I'll chime in on some of the ones that haven't got too much answer yet.
:3. Is rot contagious?
Yes, to the extent that it will spread from rhizome to rhizome within
a clump, and to nearby clumps if they are close. When rot is detected,
one should remove all the effected rhizomes from the iris bed and
either treat them or discard them, depending on how much they matter
to you.
:4. Can a rhizome ever bloom again? If the answer is no...why?
A single particular rhizome will bloom only once. Increases will bloom
in subsequent seasons. (This is also true of rebloomers; the individual
rhizomes do not rebloom, but the plants increase rapidly enough that
some increases can bloom in the fall and others in the spring.) The
reason this is so is that an iris rhizome is really a modified stem.
The bloomstalk is like the flowerhead of this stem. If you look at
most any plant, you will see that a stem that has bloomed does not
produce new flowers growing from the same spot as last year's faded
ones; rather, the newer, younger stems bloom. An iris clump is one
big plant and each rhizome is like a new branch or stem.
