Q.elephant ears leaves yellowing then browning
Why are elephant ears leaves yellowing then browning and dying? I bought the elephant ear plant for total sun area. Transplanted it in a larger pot and placed in the sun. Now the leaves (one at a time, seemingly) started yellowing, browning and finally dying.

The first thing I would recommend is double-checking that the specific needs of the elephant ear plant are being met by reviewing the following articles:
