Q.elephant ears
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.
