Re: yellowing leaves

Where are you?
If the yellowing leaves are yellow/brown, and the others have "frosted"
whitish patches, look for tiny tiny tiny little dark reddish specks....red
spider mites.  If that is what you have, (an occasional summer problem around
here, pain in the ..... neck to control), kelthane (I think that's the name)
works but Green Light switched to a useless neem or pyrethrin stuff a few
years ago; most products are equally useless despite their claims.

  Subject: [iris] yellowing leaves


  Did I see a recent discussion about leaf spot and yellowing leaves?  Today
I
  found several clumps in one of my seedling beds that are afflicted with
leaf
  spot and yellowing leaves.  I've had leaf spot before, but never with
  yellowing leaves.  Some of these clumps are adjacent to each other and some
  are distantly isolated  --  as much as 30 yards distant.  Also, the
affected
  clumps are usually trouble-free.   I'd appreciate any information and
advice.
