My elephant ear bulbs have emerged from the ground and the top of the bulb can be seen. Do I need to replant them deeper or do something else? I live in Memphis, Tennessee.
Tubers are planted 2 to 3 inches deep. Do not disturb the plants now, but rather you could lift the plants in the fall and replant.

Can elephant ears take direct sun?
It can depend on your growing zone. A cooler climate and you can plant in a more full sun location. If you live in a warm climate you will need to plant in a partial sun location.

How can they be treated to get rid of the bugs?
Most pests can be treated with Neem Oil.
Neem Oil is organic and safe for people, pets and bees!

I live in Austin, Tx where we have very mild winter. I have two elephant ear plants in front yard. Not looking great but still green. What should I do? Cut the leaves back or dig bulbs out cut off and replant??
I would leave the bulbs in for this season. You can cut half of the larger leaves off and leave the rest on the bulb. When the new leaves grow you can then prune away the remaining older leaves if they decline.

I have stored my elephant ear in the garage the last 2 winters. This year it appears to be rotting. I can easily pull out one of the trunks and the top of each trunk has mold on it, and is very spongy. There are a couple shoots coming up, but do not look healthy.
Spongy and soft bulbs should be disposed of. They are not viable bulbs.
Temperature fluctuations are the likely cause.

Why does my plant elephant ear goes to a side? It's not the first time that happens
Finding a very bright but indirect location for your plant is important.
You can rotate the plant weekly to make sure it receives even light.
Proper feeding and humidity will also help strengthen the plant.

I live near Tulsa, OK, and before winter I dug up my elephant ear tubers to store for winter. The tubers were very wet and somewhat mushy. I removed the outer layers and left them out on paper sacks in my garage for the winter. They became molded but are dried out. Should I attempt to plant these molded tubers in my flower gardens this spring or trash them and start over? They grew extremely large and were very productive and healthy last season.
I think you should plant them. Other gardeners have reported that elephant ear bulbs are very hardy and have come back after all kinds of poor treatment. There are no guarantees, but you might as well try.
