I live in Zone 5, South Bend, IN. My dogwood leaves turned brown and fell off late this summer. I didn't notice any creatures or fungus on them. Can I do anything to save it and how do it stop some of the others from having the same problem? Switching to my Hosta problem. This summer I had little holes in my leaves about the size of a pencil eraser-looked like shot gun pellet holes. Are those from slugs and if so the Snail & Slug killer didn't do anything to get rid of them. What can I do? And now to the miserable little green worm-like creatures that come out every spring and totally chew up my "Goldy Locks" ground cover-practically down to the roots. There are hundreds of them and besides being disgusting they eat their way thruough a 3'x4' garden in one day, leaving a miserable ground cover for months. Thanks & God bless you, Susan Busk
