Pests on Hostas
I have recently found groupings of very small blackish either bugs or eggs on the leaves and/or in the lower curl of the leaves as the leaves come out of the ground. Also, the flower portion that was just coming up is covered in them. I have cut the affected pieces off the plants. What are these and how do I get rid of them? Please help. I live in Calgary, Alberta, Canada.
My first thought was that was you are seeing is slug poo. Have you seen any there? Slugs love hostas and there are various treatments for them. Here is a good link.
