Hello Everyone, haven't been on here for a year. I have a very large Bird Nest fern that is turning yellow from the bottom up. I keep the soil evenly moist and try to keep the humidity up around the plant but still the bottom leaves continue to turn yellow, then brown,etc. It is growing from the center and the new growth looks healthy. Could someone please give me an idea what is wrong? I really don't want to lose this baby-so beautiful- Thanks for your help.
