Answer: Hydrangeas tend to droop if exposed to hot afternoon sunshine so try moving yours to a location that gets morning sun and afternoon shade. Daily watering might be excessive, even in the heat. Try this: immerse each pot in a larger container of water and let it sit for about 10 minutes. Then take it out and let it drain. This will force air pockets out of the soil which is common in potted plants. Then when the top of the soil begins to dry out, water each one thoroughly. Wait until the top of the soil begins to dry out before watering again.
Best wishes with your hydrangeas!
