don't know exactly how cold it has to be. My guess is in the 50F range or
In the north, we lifted tubers like Glads, etc. and stored them nearly
dry for the winter. The same will work
in the South for Arisaema storing them in the refrigerator. But, what we
really need is a good
study with a range of storage temperatures and times including control
