Hello, I came home from vacation a few days ago and discovered two plants in my yard had all the leaves on one stem/branch turn completely black. The rest of the plant appears to be fine at the moment. Sorry, I don't know the specific names of the plants. They're just the hedge and the bush to me. I've also noticed my mulberry tree has a few black leaves here and there, but a whole bunch of spotty ones that could possibly be turning. When I took a closer look yesterday I found several Stink Bugs on the Mulberry tree. I've never seen them on the tree before, but I've also never looked before either. As a side note, probably not relevant, but my lawn was destroyed by grubs last fall. We sprayed the lawn with nematodes in the spring. Can anybody explain what is going on and what I need to do to make sure this doesn't spread. I live in Toronto if that is relevant at all.
