Hello Garden Gurus! Could you please help me identify what's happening to my pieris? I planted it last spring and it ended up being somewhat overwhelmed by nearby perennials. Now that those are all died-down, I noticed that many of the leaves have brown tips tinged in red. Here are some images. When I look with a magnifying glass I can see what looks like really, really small white fly carcasses. Might just be dust. Any suggestions are appreciated. Thanks.
