Re: Re: CULT: ORGANIC SOLUTIONS/cygon/Iris Borer Deterrent

Laetitia,

I don't use any chemicals at all to control iris borers which abound in my
area too.  But since I started religiously cleaning my iris beds in the fall
after the first hard freeze, the borer problem has all but disappeared.  I
remove all the dead iris leaves, all the leaves that have fallen from the
trees and then cut my iris down to within 3 or 4 inches from the ground.  I
do not compost the debris but rather bag it or burn it if possible. This
year out of hundreds and hundreds of iris plants I saw two that were hit by
borers.  Like Mike, I'm a believer!  And I also agree that this cleanup has
to be done with all the iris beds in order to reap the benefits.

That leads me to believe they lay their eggs right inside the rhizome
leaves, dead or alive.Has anyone noticed a difference if they cut down their
leaves, and if you cut, how short do you cut them?
