It is a well-known fact that Dahlia tubers has to be stored in a frost free environment. Has anybody information about the actual temerature, which kills the tubers ?. Rumors says they are able to survive a few degrees of freezing.

Tubers are able to survive a few degrees above freezing, but it's best to keep them between 40-50 degress for most of the storage period.......I use an indoor/outdoor thermometer and place the outdoor temperature sensor in the tuber box so I always have an acurate temperature
in the storage box....it's worked for me for several years now. DB

I don't know about temperatures exactly, but I do know you mustn't place your container of tubers directly on a cold floor, even if the room temperature stays at 45-50. This year, I cut, dipped in fungicide, dried and then wrapped each tuber in saran, (as has worked great in the past.) then piled the tubers in a plastic tub and put it in the basement. A few weeks ago, I found the entire bottom layer of tubers in the container had rotted. I am glad I wrapped them all up, the rot was contained and the others are fine!

caz, May I ask what fungicide you dipped in? Into which you dipped? LOL I am convinced I have skin reactions to sulphur dust, very reliable for me, but I can't do this rash/ itchy patch thing twice a year as I have this year. It coinicides with dusting in October/November and is just now recurring after unwrapping all tubers and dealing with leftover dust. Major drag.

I'd really like to hear your alternative and how you use it.
Thanks!
