It did not affect the spring bloom at all.  There were plenty of stalks and
flowers.  I suspect that by October the plants have pretty much matured to
bloom-sized rhizomes.  But I don't really know that for sure.

While it's only been 1 year, I think it's compelling evidence.  Out of
hundreds of clumps of irises, there were no borers, with no chemicals.
That just can't be a fluke.
