Re: Siberian irises

[
RE: Question about necessity to plant Siberian Iris divisions immediately.

Last fall, I divided a HUGE (about 4' in diameter) clump of
Siberians.  They also had not bloomed that year.  Some were white,
some Caesars Brother, and some that I think of as 'Caesar's little
brother'; similar to CB, but shorter, less intense color and greener,
less erect foliage.

Some I divided into very small bits of rhizome.  Some I left as larger
clumps, maybe 8" to 12" by 3".  The larger clumps bloomed better this
year.  There were two large clumps, about 12" in diameter, that I just
didn't have the strength to divide and plant.  They sort of sat where
I'd tossed them for several weeks.  I finally turned them roots down
and tossed a little dirt around them before the ground froze.  This
spring, I stuck the entire clumps into the corner of a bed.  They
bloomed great, and proved to be CLB.

Moral: SIs are pretty tough, at least in my experience.  I wouldn't
loose any more sleep over yours.  Get them in some dirt when you can.
Cut back the foliage to 6-8" and water well after you get them in the
ground.

Good luck,
