Re: CULT: Bacterial Soft Rot


Bacterial soft rot organisms are supposedly everywhere, waiting for a
chance to multiply.  I suspect some form of soil sterilization is the
only way to get rid of it, but even that would be temporary.

If you don't want to sterilize, probably best defense is to improve the
soil in every way you can think of, make it hospitable to things that
eat bacteria and more hospitable to irises so they have a better chance
of resisting attack.

My guess is that the subsoil you used was pretty devoid of life, giving
bacteria a 'safe' place to live without any predators.   But that's just
me making up stuff again <g>
