I put in a new garden this week, and my landscaper seemed to think my hydrangea would be okay there, even though it gets full sun most of the day. I'm afraid I don't even know what kind of hydrangea I have, so I'm attaching a photo. It's very hot right now, but we've had a lot of rain, so the soil is moist. I watered the hydrangea for a long time yesterday, and it didn't look any better until it had a chance to recover from the heat overnight. Now it's drooping again. It was previously in a shady garden and didn't bloom every year, presumably because it wasn't getting *enough* sun. Now I'm afraid it's getting too much.
Any comments or suggestions?
