My lilly from Dad's funeral kept getting worse and worse. I set her outside on a nice sunny day thinking it might help. I later learned that I had scorched and traumatized her putting her outside for the day. Leafs all die and I thought she was a goner. Stopped watering the pot for nearly a month before a tiny point came out of the soil. I started watering again and low and behold, a leaf should be opening this week. Never give up!
