Re: CULT: plague/rot

She had grown some irises, but was an expert in plant pathology (PhD)
rather than irises.  She seemed to have done a lot of research on the
subject tho.  However, my dwindling memory capacity may be a factor here
<g>.  I think it can start anywhere on the plant it gets a toe-hold, in
other words, anywhere there is an injury or weakened defenses, as long
as conditions are warm and humid - our air can be as wet as some soil
<g>

Seems like we had a thread on this last year as my irises were rotting,
& at first I didn't notice the smell.  Bill Shear (I think) posted
something about carbohydrate availability and stench - less carbo in the
leaves, so not as much stink until it gets into the rhizome (that
starchy stem <g>).  Once it got into the rhizomes, you could smell it a
mile away (yes I exaggerate).  Am I remembering this right?

Jeff asked:
                <Whenever bacterial soft rot has occurred in my garden
it has always started
                 in the leaf or stem bases where they join the rhizome,
not at the leaf
                 tips. Was your "expert" a person who was actually
experienced growing
                 irises herself?
