    It's been a really dry summer. Hydrangea need lots of water and newly planted ones need even more. If they are in too bright of sun, there water needs will also be higher. Make sure they are not in direct, bright light and for the next 1-2 months they will need water weekly to help them get established and find their own water with their root system.

    It sounds like you have sooty mold. This article should help: https://www.gardeningknowhow.com/plant-problems/disease/how-to-get-rid-of-sooty-mold.htm

    This is a fungus caused by pests. I would treat the plant with neem oil. It is effective against the pests responsible as well as the sooty mold. Here is more information that may help you:

    Generally, wilting of hydrangea is caused by a watering issue. It may be overwatered. Check the soil and make sure that it is damp, but not soaked. It should have adequate drainage.

    It could be either black spot or sooty mold. Both are treatable and, in most cases, not fatal to the plants. These articles will help:

    I don't know why it doesn't bloom but I have four hydrangeas and they bloom every year. Every fall I cut mine back about 2 feet from the ground. One is a blue/purple, one is pale pink and the other two are a medium to darker pink. Obviously where they are planted has a lot to do with the colour of the flowers however, my blue/purple and darker pink ones are planted next to one another with a wooden fence between them. I would try planting it by itself away from plants with spreading roots. My blue/purple one gets very little sun and the other three get mostly afternoon sun.

    Typically, in hydrangea, this is caused by a watering issue. Since it's newly planted, there may be gaps in the soil around the root ball that is drying out the roots. I would tamp down the soil around the plant. I would also recommend upping the watering. In addition, it could be suffering from shock. This article will help with that: https://www.gardeningknowhow.com/plant-problems/environmental/learn-how-to-avoid-and-repair-transplant-shock-in-plants.htm
