Hello. My hydrangea is struggling with brown flowers and unhealthy leaves. At first I thought maybe it was bugs, so I sprinkled some sevin dust all around and on it. It hasn't helped any! So here I am, desperately seeking advice...

Can anyone suggest how I should go about saving it?

Thanks in advance!

This is at least Cercospora leaf spot, a fungal disease. There may be other diseases (fungal or not) present as well.

You need to spray a systemic fungicide such as tebuconazole as soon as possible. Follow the directions on the bottle and re-spray in a week.

Don't rely on surface fungicides like neem oil as the fungicide needs to enter and be absorbed by the entire plant the way only a systemic can do.
Keep going!
