The last of the plants that were stored in my garage this winter are the Elephant Ears. Apparently not only will I never need to buy another one of these again in my life, but nobody I know will ever need to either. It seems there's no wrong way to store these and have them survive the winter -- as long as they don't freeze.
Two autumns ago I just left them in the large pots, then dragged the pots out in the spring. This year I left three of them in their large pots, but also stored one bare on a shelf in the garage. Since they're starting to wake up now, it's time to get them out of the garage.
