Hellebore Feotidisima sooty mould ...
Hi There, I have a Hellebore Feotidisima which is about a year old. It is doing very nicely and I think pretty happy. But I have noticed recently some grubby, rather 'sooty' looking markings on it. I have also observed a mild infestation of aphids. So I reckon this is 'sooty mould' fungus and not the 'blackspot fungus'. Can anyone tell me whether it is potentially harmful to the plant, and whether there is anything I need to do to treat it? Or should I just leave it? I have a feeling this problem is more common on this hellebore variety that on other varieties.
Best wishes, Jonathan H.
