I have dug up and disposed of a large clump of older Irises and of course when I did I found signs of Iris Bores. here's my question, what do I need to do to the SOIL where the irises were planted that would make it safe to replant more Irises? I read here on this forum to pour dishwater on the spot but I don't understand what is in dishwater (beside soap)that may be effective or why not just mix up big buckets of soapy water and use that for treatment? This fall I intend to use the blowtorch treatment and next spring I will use Merit earlier. I used it this spring but I must have waited too long for it to be effective Thanks for any information |

| what does the soil have to do with the bug??? would not you just treat for the bug at the appropriate time of year? ken |

| Never heard of treating the soil? But I'm a newbie. My mom always just lifted the plant, squished the borer, dipped the corm in sulfer powder and replanted. Her Iris are stunning! |
