Sorry in advance for asking several questions. Just given a large elephant ear plant as a gift. It has what looks like two, thick separate stalks but could it be one tuber? I live in NYC, so I know the plant cannot be outside in the winter. I am considering planting it in a large aluminum container rather than in the ground so I can bring it indoors for the winter. Do you advise that? Is it possible to keep it indoors and continue to grow? Is it better to cut it down or let the leaves die and store it in my basement, although it can get cold there also? Thank you for your help in advance.
It's possible that the plant is growing from 2 tubers, but probably it's one tuber that's sent up 2 stems.
In your area, you're going to want to keep it in a container, and put it outside during the warm months, and bring it in for the winter. This article has more information: https://www.gardeningknowhow.com/ornamental/bulbs/elephant-ear/growing-elephant-ears-indoors.htm
Fort Worth, TX - Why do I have a yellow leaf on my elephant ear plant?
One yellow leaf doesn't usually mean much other than that the leaf got old. Plant leaves get old and worn out, and don't work very well anymore, so the plant pulls out the materials that are in it for use elsewhere, and let's the leaf go. You might want to dig with a shovel to check the soil moisture, it shouldn't be too dry or too mucky. Here's an article on elephant ears that might be useful to you: https://www.gardeningknowhow.com/ornamental/bulbs/elephant-ear/growing-elephant-ear-plants.htm
I planted them in my gardens and some of them have wilted and turned brown.
There are many species of elephant ear, with differing needs, so the first thing is to make sure yours has the light specified on the plant tag. The next thing is moisture -- elephant ears require moist soil, but even they can be drowned. Too much moisture and too little moisture can result in brown and wilted plants. This article tells you how to determine the moisture in the soil: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/testing-moisture-in-plants.htm

I repositioned the plant from morning sun to no sun at all but some leaves are still burning. I make sure the plant is well saturated.
This article discusses some reasons for leaf burning for you to evaluate. https://www.gardeningknowhow.com/ornamental/bulbs/elephant-ear/elephant-ear-brown-edges.htm
One other thing that isn't mentioned in the article is age of leaves -- if the browning is on the older leaves, that could be the cause.
All of the stems of my large elephant ear plant broke off while moving into house. The central stem is now completely brown and dry. Is it dead or can it be revived?
If the plant had been growing in a pot the whole time, it should send up some new leaves eventually. If you dug it up from the ground, if you brought enough root, it should be able to send up new leaves. Of course the dead, brown parts can't be "revived;" they are dead. The only thing the plant can do is grow new leaves.

I have elephant ears and they are so big - the bulbs are 2 foot long. Can I cut them in half and replant? I store them for the winter. The bulbs are about 10 years old, but they're just so big.
There are many many varieties of elephant ears, in many different sizes. You apparently have a large one, and one that is hardy in your area, which is kind of rare. I'm assuming that this is the first time you've dug the tubers (they are technically tubers rather than bulbs.) You can break off smaller tubers that are emerging from the big main tuber, but the big main tuber should be left as is. Since you've left them in the soil over the winter, you can probably rebury them around 6" deep, then cover with up to 1' chopped up leaves for a mulch. You might want to overwinter some of them in a dark place, following these guidelines: https://www.gardeningknowhow.com/ornamental/bulbs/elephant-ear/storing-elephant-ear-bulbs.htm
Just need to know if my elephant ears and caladiums need to be taken out of the ground in the northwestern part of South Carolina? Or can they be heavily mulched and survive staying outside? Thanks!
Caladium and elephant ears are both tropical plants; the standard warning for temperatures is nothing below 55 - 45F, although sometimes they can withstand a few hours 38 - 32F. Kind of a broad range, because there can be a variation between cultivars and individual plants. In your area, which is sort of on the border, some people would recommend you to dig them up and overwinter indoors, others would say you can keep them outdoors under heavy mulch. If you have enough plants, you could try both approaches, just to see what happens. If you bring in the caladiums, treat them the same as the elephant ears.
