i can't think of one thing that's changed. i keep it at work on my desk. this morning when i came in it was soooooooo horrible!!! i decided i had nothing to lose so i moved it to another desk, closer to a window. I'm wondering if it was too close to a heat vent? it sat in the same spot last winter though. i also gave it some superthrive on friday. how often does it need to be replanted? what kind of soil do i use and how do i do it? sorry for all the questions.....this plant is just so important to me. my boyfriend (at the time) had taken me to the japanese gardens in dallas and then bought me this plant the next week as a surprise. this plant MUST live!!! thank you so much for all your help!
