Q: What is causing my hydrangea leaves to get these spots?

A: That is unwelcome Cercospora leaf spot, which is a fungus brought on by leaves staying wet, either from too much rain or overhead watering, and this heat & humidity isn’t helping! Some leaves will brown and fall, and that can’t be avoided. But the good news, your hydrangea is going to be okay. As with diseased leaves on other plants too, it’s always good practice to remove them from around the base of the plant as soon as they fall.
