A couple of months ago I was given a maidenhair fern. Due to neglect, I believe I have a problem. The leaves have all turned brown. It was left in the wind one day and copped a flogging. It may have also been over watered, as I was doing it and so was my son. I have now moved it indoors into the lounge which gets the eastern morning sun. What can I do to restore it to health and how do I look after it from here?
