Which hellebores should have their old leaves chopped to the ground and which should not? At what time of year should they have their old leaves removed? Should it be done only if their leaves appear infected with black patches, and not if the leaves bear no evident infection? And should all hellebores be treated the same way, or are there some type which should never have their leaves trimmed right down (I am thinking particularly of 'Feotidisima' and 'Argutifolius')?
This plant in the photo is a red flowered orientalis type and quite young. Its leaves do look just slightly blackish all over.
