Spot damage leaves

“Bought some fire light hydrangea last year that seem to have some sort of issue going on. Not sure if it is disease, fungus or insect related. I will upload photos, was hoping you could provide thoughts on what is going on and how to treat it. Any advice you can provide would be greatly appreciated!”

This is damage from the four-lined plant bug. Lots of people mistake it for disease since it’s so spotty looking, but it is indeed an insect. Lots more info here: I would recommend looking at the plants in the morning when the insects will be present but slow and hand-picking any that you see. Look for both the yellow adults and red nymphs…just saw the red guys on my mint yesterday, in fact.
