Insects on my hellebores
I have mature hellebores in a semi-shady spot. The ground underneath them has some leaf mold from the winter. I was trimming off the old leaves a few days ago and noticed what I think is a huge aphid infestation. There are sticky , shiny areas on the leaves, small white specs on the leaves and columns of white things on the stems. Some small greenish insects were on my t-shirt. This has never happened before (the plants are 5-6 years old, maybe older). I still have the flowers on the plants, most turning into seed pods now. How should I treat the plants?
From your description , it appears that you may have aphids.Removing the older leaves is a good idea in the culture of growing helleborus. No need to treat the plants at this time, the beneficial insects should keep them in check.
