If this is true, that explains why we have never had 'smelly'
rot. We are too cold. Finally, a benefit for our climate plus we
have never seen an iris borer in our gardens. Has to be the
extreme cold - there is no other explanation that I can come up
with for lack of Erwinia c. or the dreaded borer. 

Not complaining in New Hampshire,

snow is melting. Early spring here means late April.)
