This is my peace lily Mary, I have had her for nearly 2 years. She is sentimental to me because I received her after the passing of my dear grandma who she is named after. For at least the past 2 months she has not been looking good. Black edged, weak leaves and droopy. I thought I may have overwatered so I waited for drooping to water. And even though I have not watered her in a week the soil is still damp. I have fertilized and trimmed off the black edges but they still come back. I find even after watering the stems have a bend in them. I have her near a window with indirect sun. Maybe repotting? What can I do? Please help!
