Re: iris borer
Borers should not be much of a problem if you do a good clean-up of all foliage in the fall after frosts have killed it back and again in spring before temperatures hit 70 degrees. They look like meal worms and eat into the fan and then down to the rhizome. Here's more info from an AIS affiliate site:

I am so glad we do not have to deal with this pest out here.

Re: iris borer
Interesting information Mike, thank you for the information. I have passed this along to DH whom thinks I'm nuts picking up all
the leaves that blow into the yard. Interesting about the burning in the spring. I'm having trouble with slugs this year.

Re: iris borer
Karma - No worries. The borer and it's moth cannot survive on this side of the Rockies. If they could have they would have overrun the west coast iris fields decades ago. We're safe from this pest. Good idea anyway tho as it helps minimize leafspotting.
