However, be careful. take too many leaves right now and during the summer will weaken your plants and affect flowering later.
I had hell black spot on several plants last year and removed a lot of leaves. Those affected plants hardly flowered this year. the remaining hellebores flowered profusely.
I'm aware of which hellebores are susceptible and they are part of a spraying programme. Seaweed spray, Epsom salts and systemic fungicide/ neem oil.
its difficult.....the affected leaves will spread the spores so need to be removed.
Assessing my own hellebores I concluded too that humidity is a factor in developing black spot....keeping hellebore leaves as dry as possible.
