How to Identify and Treat Hellebore DiseasesWhile hellebores typically have a reputation for being trouble free, they can occasionally fall prey to disease.

In this guide, we’ll cover how to diagnose an infection on your plants and take the appropriate action to prevent the disease from spreading.
Here’s the lineup:
1. Black DeathHellebores may be prone to infection by a fairly recently discovered and dreadful viral pathogen, the Helleborus net necrosis virus (HeNNV), that causes a disease known as the black death.
You should be highly alarmed if you see black blotches and streaks on the surface of the leaves or flower bracts of mature plants. There is a good chance that your plants are infected with the virus that causes black death.
Other signs of infection include stunted growth, brown or black leaf veins, or dark spots on the bracts and petioles.
As the name “black death” suggests, there is little hope for saving your plants if they are infected. You’ll need to dig them up and dispose of them in the trash to try and contain the infection.
Experts believe that this disease is spread by aphids, so you may want to treat any uninfected plants with an insecticide to keep these pests at bay.
Additionally, be sure to disinfect your pruning shears and any tools that you used on and around the infected plants.
The only bright side is that this disease is typically more of a problem in plant nurseries
