I keep it moist almost all the time, besides here it rains a lot, but now the trees around it are decidous so they don't have a lot of leaves and the sun is getting to my fern a lot more, but it has two other ferns at his sides and they are doing good, so is not the sun. I was looking very closely to the trunk of the fern and it looks like dry and many of the leaves are brown and yellow and are looking drier than usual, normally they look very alive and healthy. I love them and I'm very worried because I red that usually when they get infected is devastating. Please help me. Thank you.
