Thanks. I don't have photos of them, but basically large portions of leaves like half the leaf or more on a lot of leaves appear to be chewed off from the edges but also long sections of leaf btwn the veins turn brown and develop lots of holes. I treated with Sluggo last year, general insecticide, neem oil, and a light peroxide solution. The peroxide damaged the leaves too much but they survived. The front of the house faces West, and the hostas are in the garden adjacent to the house which extends about 5 feet from the house. There are 4 or 5 hostas w/ green and white striped leaves and they get about 4 feet wide and 3 feet tall, pretty big. They've been growing larger every year. I think some of the damage is prob due to excessive sun since they get direct sun a good portion of the day unfortunately. But I didn't plant them they were here when I moved in. After I did all the treatments listed there was improvement (lasted longer into the season) but I still got similar damage so I am suspecting nematodes from some research. There are no shoots yet so I am eager to try the ammonia drench if I can just figure out how to do it.
