I did that many years before, but stop washing this year.
Yes, I agree washing remove most spores from the suffers of
tubers - this is good for storage, but I suspect that water remove
compounds required for protection tuber too. Washed tubers
need some time to restore protection when they planted in the
spring and have more chances to rot then not washed.
I have only preliminary date about this matter. Next year I am
going to test anti bacteriological properties of water-soluble
compounds extracted from tubers suffer.

It's interesting to know any other way to reduce rotting.

In my "indoor arisaema factory" I store many young tubers in the refriger=ator
at all times of the year, creating the "artificial winter" needed to shor=ten
the time from seed to maturity. I do this entirely in plastic kitchen sto=rage
bags containing slightly damp turface (the smaller the tuber, the more
moisture). I usually don't wash the tubers before storing them. I have ve=ry
little problem with rotting using this method.

I think that Barry Yinger and Andy Wong (Asiatica Nursery) use dry sphagn=um
in ventilated plastic bags for storage, but would hope that they might
confirm or deny this. Sphagnum is said to have antifungal properties, and
might offer the best avenue for avoiding winter rot of stored tubers.
