This is my Berry White hydrangea. I think they're may be more than one issue here, as there are some yellow leaves, crispy edged leaves, muddled spotty leaves, and perfectly green leaves. Notice they're are some 'rogue' shoots at the top, as well. We have had a fair amount of rain and some really scorching hot, humid days. The hydrangea is on the east side of the house at the south end. It's around 4 years old. Scorched? Fungus? Too much water? Too little? Ugh. I don't know what to do! Thank you!
