Diffuse dying hellebore in our front and back yard

Question: Over the last month our hellebore plants (over 50 of them and we cut them to ground last fall and new growth was initially bright green and flowering as usual) have blackened and shriveled up on each and every plant.  Flowers as well.  I don't see any insects on plants.

Please let me know if you can diagnose problem and if any suggestions to improve their health.
Thank you. KJ

response: I haven't heard back yet about our hellebore plants.  Is there another way to connect?  My main question is should we destroy these plants, roots and all? or is there a treatment to restore their health?  Any feedback would be appreciated.     Sincerely, Kathleen J  On 05/26/2024 3:29 PM PDT Ask Extension <<personal data hidden>> wrote:        Dear Kathleen, Thank you for using Ask Extension.

response: My apologies. I just received your question. We are dealing with some administration problems in the system recently.  I suspect Hellebore Black Death virus.
