  refrigerating tubers
From: Lester Kallus lkallus at earthlink.net> on 1969.12.31 at 16:00:00(10865)
Last March, I came home from a trip to find that a konjac had sent an inflorescence up in my basement, the spike had shot through the space between the shelf system and was in the process of trying to open up. Another tuber,fortunately, remained in hibernation until it was warm enough to put the plant outside.

There's no cool area of my house- the basement is heated. Consequently, to keep Canna rhizomes and carnivorous plants alive over the winter, I've purchased a refrigerator for my basement.

Now the question is: What would be the ideal temperature to keep the tubers in hiberation but not induce any temprature-related injury? I assume the Canna would do best around 45 degrees F (7 C). Would that be OK for kojac?

One of the atroviridis is also trying very hard to send up a spike. Would it survive in that same refrigerator or shall I give up and allow it to grow?

Hi Les,
My konjac's do just fine in my basement with temps in the low 50's
(F) and a friend of mine keeps his in a root cellar at even lower
temps, probably closer to 45F. As long as they are kept away from
any dampness, they should be fine. Don't know if this applies to any
other species.

I find the flowering stalk to be 'less resistant' to being held dormant
by cold on konjac and if it wants to go it goes. I would not risk
stopping it by going any colder than 44 or so. I once stored a big
konjac in a refrigerator at 38F dry and it received enough cold injury
to have the tuber rot. Remember that the flower stalk must preceed the
leaf and if you are to get the leaf out in time to renew the tuber
stalling the flowering until late spring would not result in good
vegetative growth unless you have a greenhouse or live down south.

I wonder what the minimum temp for storing Konjac is .. I store them at an average temp of about 50F.. but I know it can dip down to about 46-44F ... so will this be a problem ?
