How long can I expect the flowers to last?
On a shrub the flowers will last throughout the summer into late fall. Some varieties, the flowers will dry on the plants and can be left for winter interest.

How can i tell if my shrub is dead. I have a couple of bushes, one which is a hydrangea bush. The leaves are green but the flowers are brown and brittle. I also have a "little devil" shrub and it is wilting , is brittle and appears to be dying . Are they diseased?
If branches snap or break off, they are dead.
Live branches will bend.
You can also scratch the bark to see if it is alive.

Why are my hydrangea's wilting and drying up? They came on strong and straight this spring but have since began wilting and drying up.
Pull back the mulch and check the moisture levels on the soil.
This looks like it could be due to either lack of water or poorly draining soil and root rot.
Mulch is good to help with moisture control and keeping the plants cool, but it should be back about 6 inches from the base of the plant.
I would trim away the dead plant material and review the care information in the link below. Make the watering corrections and see how the plant responds.
