I've only had the Elephant Ears for two years in big pots on my deck. I dragged them inside in front of sliding doors, watered (too) well, and left for the winter! One visit in Feb. this year and I watered again. The leaves die. I cut everything back when I return and water. I drag the huge pot back outside when its warm, and feed it. I skim off and add new potting soil. The first year I over-watered and had a bulb rot.I will see how they did when I go back in June. I leave a huge geranium too. Last year it came back but it was watered a couple of times. A coleus that was down to two stems revived into a Huge plant on the deck! It's always worth a shot to winter over. I have a rose in the cool basement that I had cut back. It had lanky stems and a rose in February ! No sunlight, no heat! Ya never know! Cut it back again and it came back beautifully outside.
