Others may have had luck letting Alocasia/Colocasia sleep all winter and they come back the following year but that has not been my experience.
I bring them inside before the frost kills all the leaves and keep them in my laundry room half alive. I do not remove them from their pots.
They usually grow one leaf and another one dies but as long as I can keep them almost alive they live to grow quick the following summer. I just sprinkle a little water on top of the soil to keep the soil from drying out completely. That is about a glass of water once a month.
