I had some several years ago that weren't doing good - too many tree roots around them. I pitched them in the woods. Lo & behold they just showed their heads so I dug them up & put them back in the shade garden. I don't think you can kill hostas!
Hostas are hardy. Had some over a sewer line that had to be dug up. The workers really didn't care about my plants. I thought they were goners, but now I think I have more than I had before. Just coming up in different places. My great big dark blue-green ones, though, are struggling.
