Agree that they will grow in any exposure, but if you want the really big leaves, mostly shade is best, IME (a few miles north of AL/FL border.) I moved this bulb this spring from a much more sunny location where it had been for a few years and it's making leaves about 10x bigger than before. (The babies bulbs that were with it were also put in more shady locations and are all much bigger than the mama ever was in too much sun.) I also have a mini-compost pile at the base of it, and put mostly greens there, like watermelon rinds and other kitchen scraps that "melt" quickly in the heat. Next to it is a 5-gallon bucket with a slit in the bottom. I fill up the bucket and it takes a couple hours to drip out, which I try to do just before the sun hits it, so it has ample moisture during that time, about 90 minutes of direct sun. Otherwise, the leaves fall over. After they do that, they might or might not stand back up so I put a tomato cage around it. The newest leaf on this plant is about 6 ft. tall and about 3 ft. long, which is about 8" longer than the last leaf. Constantly losing a leaf is common but happens more slowly if there is ample moisture and plenty of organic matter in the soil. I usually leave the dying leaf connected but bend it back to rot near the bulb. Unfortunately, I don't usually have rain water for it, but start by dumping the water from the bucket our dog uses for his water bowl (which came from the hose the day before,) then fill the rest with the hose. With splashing and the dripping that happens before the bucket is full, I estimate it, and the other plants sharing the root space, are using about 6 gallons of water per day, some of which is probably taken by a large oak tree nearby. Just an ordinary Colocasia esculenta I got from Lowe's about 10 years ago. The leaf that is leaning out didn't seem like it would bend into the tomato cage without breaking and since it was the oldest (going to yellow and die soon,) I didn't make any effort to cage that one:

trim the worst leaves off leave the best 1 or 2..lots of light warmth and no water till it puts out a new leaf. if you keep putting the water to it you will get rot since it has very little leaf to take any energy and use the water.

WOW, what big ears you got. sorry, couldn't resist. wont they die back in a few wks? In the meantime you could just remove a few leaves. If you dig them out you will loose lots of leaves anyway.

I don't think you can hurt them. I yank them up, breaking the bulbs/rhizomes, whatever, throw them in the back forty because my chipper/shredder gets totally constipated if I feed it elephant ears. I have to flip them over every few weeks as they begin to root and grow. You can't kill them unless you really work at it.
