Q.Potted elephant ear plant
A friend recently gave me their unwanted elephant ear plant. It is in a very large pot and since it’s getting colder I decided to bring it inside and placed it near the biggest window that gets lots of sunlight. Immediately the leaves started turning brittle, brown and eventually died. What should I do now? Should I cut the plant down, dig it up and store for winter? Will it grow back next spring if I put it back in the pot?

Even with the sunny window, the plant will still be getting less sun indoors than outdoors, and this causes many plants to lose their leaves when brought indoors. Digging and storing the bulbs over the winter is the best option. They should grow back just fine next year:
