They get plagued with tiny shiny green leaf beetles, they make the holes. you may see them and kill them, but they dont last long and the new leaves in the Spring will come out ok, if you can put up with it for now. You cant split them. each is one plant, nothing to split.
Garden pests are a way of life, if you are willing to share with them, they will go away, probably only to be replaced by another pest!!!
Thats gardening for you. xx
