Re: disinfecting beardless iris

 

I've used bleach on beardless iris. LAs and spuria do just fine. Others may be more sensitive to the bleach. You can limit any damage by following the bleach with a diluted vinegar rinse to inactivate the bleach.

Subject: [iris-species] disinfecting beardless iris

 
I'm looking for experience and advice disinfecting beardless iris.
Bearded iris rhizomes are quite tolerant of a 10% bleach solution; a
bath of 10 or 15 minutes followed by a thorough rinse does a nice job of
killing any pathogens on the surface. I've done this a few times with
beardless iris, but am wondering how safe this is in general. Are there
types of iris, perhaps ones with sensitive roots, where this will
seriously damage the plants.
