Re: Iris Diseases - Goiter

Walter said,:

<< Many times Oregon-grown irises will come with a puffy, thick neck,
 that point where the central leaf joins the rhizome.  In areas of high
 humidity and heat, this neck can act as a cauldron ...and moisture in this
neck can boil and start the rotting process....The person who coined the term
iris 'goiter' always cut the central leaf away from the rhizome upon receipt
of irises from Oregon.  If  the neck is quite puffy, I do the same thing
because I had problems with
 rot starting in the neck on Oregon plants.  I have even received plants
 from Oregon already rotting when I opened the box, and the rot had started
 at the neck.  So, I believe that this is a definite problem. >>

This is interesting. Do we know what creates/causes the "goiter"? I've had
some pretty  peculiar looking rhizomes come in from other places and assumed
it had to do with itensive growing practices. 

As a matter of course unless I can tell they have been out of the gound for a
while I let virtually everything dry out for a couple of weeks before I plant
them, especially if they are going directly into the ground rather than into
pots with growing medium rather than soil. "Adjustment Rot" problems are
lessened for me because they are so grateful for the water when it finally
comes they just sop it up and start off. Most of them. So, do you cut off the
whole center fan at the rhizome, Walter, if there is a "goiter"? I've had
some plants come in with so much increase started in so small an area that I
knew there were going to be problems before it was over. Next time I might
exise a fan or two. Whadayya think?
