What Could Have Killed All My Ferns And Hostas?

Question

I have 5 shaded flower beds at the edge of the woods. I live in southern Ohio. I grow mostly hostas and ferns. Daffodils come up in the spring. This year the daffodils came up but not a single fern or hosta in 2 1/2 beds. What could have killed them all? I don’t fertilize them. I do have mulch put down every year, but this is the first in 20 years that nothing has come up.

And they were healthy last fall? Was it a wet winter that might have caused root rot? These articles should help:
