Rot Prevention

From: "WEAVER,BILL (HP-USA,ex3)" bill_weaver at hp.com> on 2001.12.17 at 22:29:15(7934) Okay, maybe I stirred up a hornets nest here. What I was trying to do was find a way to insure that my dormant tubers come back next year. I store my dormant plants under the bench still potted up in their pots. I do not disturb them to re-pot until I see signs of growth. During the time they are dormant I find it a good idea to keep them very slightly moist so that they don't desiccate during their dormancy. I was just wondering if it might be a better idea to use hydrogen peroxide instead of water as the moistening agent during dormancy.

Basically, he waters the plant on its regular schedule, but for three waterings he uses hydrogen peroxide. His reasoning was that apparently plants (at least orchids) produce a weak hydrogen peroxide solution at the interface between leaf and stem when the plant is dropping a diseased leaf. His reasoning being that if the plant produces it inside, it should have no problem with it being applied on the outside. Long story, short question. Does anybody have any idea if this procedure might help combat rot in dormant potted amorphophallus tubers? Bill Weaver bill_weaver@hp.com
