Re: Re: Iris Borer Dete

Laetitia,

I am no expert but I in zone 7 have raised a few Iris.  Well I read some were to mulch iris, so I put leaves around them.  Oh what a mess come spring.  I had never seen a borer to speak of until I did this.  I had so many of them. YUK!  I have put mulch between them, never leaves, not over them, and had a whole lot less problem with these borers.  I don't put mulch directly on them here but maybe you have to in cold areas.  Please avoid leaves.

  Well, I was desperate, having actually seen borers totally KILL iris 
  that had been blooming only a month before, and I bought the stuff 
  (before I read these posts). I don't want to use poisons (ie CYgon) 
  if I can help it.
  I have squeezed iris fans, and the b's  don't die.
  I have operated on rhizomes; plucked borers out with an eyebrow 
  tweezer, made sure they had gone on to the great beyond, and still,
  other borers came back that very night and drilled new holes UNDER 
  the rhizomes.
  So you see, I'm desperate AND angry.
  I will report back next spring on what happens with this stuff...I 
  do not intend to use any other poisons; but I will remedy one very 
  bad mistake I made: I let lots of leaves and weeds grow around the 
  iris, and lay there thru the fall, winter and spring.
  Thought it would make a nice 'natural' mulch. (yeah, right!)
  I plan to wait till maybe early December, when I'm sure those b's 
  have laid their vile eggs, then give everything a haircut AND blow 
  dry, and cover the whole thing with cedar chips.
  I dare one borer to show its ugly red head!
  Laetitia
