I grow turmeric ginger. They naturally go dormant here in my zone around December. Our coldest night temp does not usually fall below 70F. The stalk and leaves die down then the rhizomes begin growing again I think 3 months later. So, I think it is perfectly okay to store your rhizomes in a cool (not freezing cold), dark place until it is warm enough to plant them again.
