Re: Spring Rot?

Thanks Ellen, and Pat Too!
We're getting a good 'Nor-Easter here. . . we now have a foot and a half of snow.  Good thing we have a 6 foot snowblower!
I'll be watching the iris as soon as the snow gets off. Come to think of it, it was smelly, and it killed my more expensive one. . . Yaquina Blue, established already one year.  I think I have about 20 plants with severe enough rot to keep them from blooming this year. . .maybe more.  
I don't think that they were ready to bloom.  There was still frost in the ground, and the crocus aren't even up yet.  The new increases were only 2 cm tall. :-)
Thanks for your help. . .I'll keep you posted on how the comet and chlorox works.

Hello Bo,

I am in Zone 3 and I never trim bearded iris...some do around
here but I tend to be too sloppy with my trimming and find that
I do a lot of tearing of the stalk which seems to say, "Hello
rot, have a seat on one of my newest $40 or $50 rhizomes". (Rot
seems to leave the $5 bargain TBs alone...) 

>>> Do I have some strange bacteria in my soil that hasn't been
there before? <<<

Dunno but I always have at least a small bit of rot in the
spring but it is not the smelly kind. Mine is from the moisture
of the melting snow and the incessant rain in April-May.

>>> I put bleach solution on, as well as Comet. . . does this
really work? <<<

Comet works the best for me...true, you do shake some of the
powder on the soil around the rhizome which I have told myself
is good for the garden. Besides, I am not good at painting
anything. :-)

>>> now we have 6 inches of fresh snow. . . it looks like it'll
be here for at least a week! <<<

I hear you....we still have snow....I also tell myself that this
is good for the garden, too. 

>>> I hope someone can help me. :-} <<<

If your irises are covered with snow and you have 'Cometted'
them, you have done what is advised in very cold climates. I
would really doubt that you had any signs of bud formation in
your rhizomes 'but' you are another zone warmer than us. We are
still frozen..and muddy in the dogs' area of the property.
Lovely spring = half snow/ half mud. Ain't it grand?
