bird’s nest fern
A month ago while on vacation, my granddaughter watered my plants. I noticed after about 2 weeks some of the leaves were turning brown. I called and ask her if she had watered them, she said yes and also fertilized them. She said she fertilized them with fish fertilizer. Could this be what is wrong with them? If so, what can I do? It looks like they are dying. Please help if you can. Thank You.
