I read somewhere I should cut my elephant ear plant down to approx. 6 inches for the winter if there is several days below 20 degrees. So I did. Now spring 2014 is in and looking at the base of the plant is green but the outer layer around the base there is a hard brown/black layer, and some parts are soft and wet. So I pulled the hard brown/black layer parts off and scraped the soft layer parts off. The top of the plant is very wet. What should I do now?
