My 3-year-old hydrangeas produced many blooms in mid-June. They are nicely formed in the morning, but by noon they are very droopy with the individual flower petals separating. They do this even after being watered in the morning. I have fed with Muracid in fall and early spring and then added aluminum sulfate to get blue flowers. Is there another feeding vehicle to make hardier blossoms? Thanks, R

You may want to try increasing their water. They may need 2 waterings a day, instead of 1 or the one in the morning needs to be longer, especially if the temps have been high.
Hydrangea are meant to be shade or part shade plants. If yours is out in full sun, it is going to need more water support to keep from wilting halfway through the day.
If you still feel that water is not the issue, check the roots. It is possible that it has root rot, which is affecting its ability to take water up and thus it wilts like it is not getting enough water.
