Rick Tasco wrote that the West Coast Irises did well for him when he
lived in Virginia, but that he had borer problems. Kentucky is Iris Borer
Heaven. I have seen the Borer attack any kind of Iris I grow, but they
prefer the Tall Bearded Types. The Iris Borer does not appear to pick and
choose only Irises that originated in one part of the country.
I would like to here more on less toxic measures to control the Iris
borer. Cygon and Lindane are the only two things I know of that will kill
the Borer, but if there is a less toxic chemical, I would like to know of
it. Like Graham in England, I have concerns over the safety of that stuff.
