RE: Verticillium wilt

I know the prognosis for Pelargoniums is zero, zip.  Mine have acquired it
a couple of times when I retrieved hybrids I'd earlier tossed in the
weedbed.  Cutting the first visibly affected stem is useless because the
wilt has already entered the bloodstream....er, vascular circulation of the
plant.  (So now I never second guess a discard.)  Yes, it is in the soil.
Tomatoes can  get it which is why many are bred with specific resistance.
There must be a lot of info. on the web.
