sword ferns turning mottled and brown

Asked May 19, 2016, 4:54 PM EDT

I have dozens of sword ferns I have planted over the last 20 years. I am familiar with the browning of the old foliage each year but this year even some of the new is turning brown and mottled along with over 50% of some of the rest of the foliage on some plants. It would be terrible for me to lose them so I hope you'll have an answer. This is the first year I have seen this kind of damage. I will send a photo in another email from my phone. Thanks Lori Hendrick MG class of 1996
