Every year my hydrangeas go into this fast dying phase. They look beautiful and healthy for a month or so and then quickly die. What can I do to keep my plant from looking like this every year. Is it the soil or is it some type of bug? Any help is greatly appreciated. Thank you.
This appears to be a fungal infection. Usually this will resolve itself over winter, but if this is persistent, then you might look at treatment options.
The treatment that I find most broad spectrum, and safe will be the use of dolomitic lime and wettable sulfur together. This will kill off the infection as well as recondition the soil back to a proper pH, and condition.

I have two hydrangea bushes. The blue one is healthy and huge. I know it is the variety that grows on old wood. My pink one is much smaller and although it has wonderful green leaves, it doesn't bloom. They are planted on the ese so sun should not be a problem. I put coffee grounds under the blue one and it produces very blue flowers. What can I do about the pink one?
You can try putting some dolomitic lime, and a fertilizer heavy in phosphorus and potassium down. These will help promote blooming. There is the probability that the smaller one is a big leaf hydrangea. If this is the case, then you may see blooms, or you may never see them again. It will be completely up to the plant! This is common, and hard to avoid.

How to care for hydrangeas in the fall & winter
There is no special care necessary. Pruning technic and time for hydrangea depends on what type you have. See linked article. If you don't still have the plant tag, refrain from pruning for one year and observe your plant. You need to establish if it blooms on stems formed this year or on new ones that sprout next year. Some of the newer varieties like Endless Summer bloom both on old wood and new wood. If you wish, remove the spent blooms but not the entire stem. Come spring, these dead-looking stems spring to life and it is easy to prune too much and accidentally remove next year's blooms. With all perennials, it is important to water them if autumn or early winter are dry and soil becomes dry. Roots need moisture and a plant that has dried out is much more susceptible to winter kill. Mulch the rootball and crown with several inches of chopped leaves or straw and pull it back from the crown early next spring.

Our hydrangea's leaves have turned brown/black. Is this normal? Have just moved into our house and never had hydrangea's. I am not sure about care for them.
Hydrangeas love water, but excessive irrigation or wet foliage injures plants. Insufficient water causes leaves to turn black or brown. ... Prolonged moisture on foliage creates a breeding ground for disease pathogens, which leave black leaves.

O my hydrangeas, which bloomed prolifically this year, now look like this period they all had some fungal leaf damage , too. Should they D cut back now ,And if , How far ?
Hydrangea pruning differs on the plant variety.
Since it is not clear what type of fungus that you are dealing with it is difficult for me to help you determine a treatment method.
Since you treated with a fungicide, you should likely wait out the results and health of the plants during this growing season.
