Blossoming Questions

I planted 5 hydrangeas and two have green wood beneath the soil, two have each one green leaf sprout. My fifth shows no sign of life! I did not cut wood down as they are only 12 inches as these were new plants – I do not see anything happening on the old wood. The buds are hard and dark brown (look dead) – they get morning sun until about 1 pm then are in the shade for the rest of the day – soil is moist but not wet and I’ve added fertilizer—is this normal for June? What else can I do to make them thrive?
Do I add acidic soil like a normal hydrangea?
I bought five hydrangeas two are doing excellent well maybe even 3. One of them is doing pretty good it’s got a bud that doesn’t seem to be doing anything but my problem is the fifth one has gone from a nice size green foliage to a little scraggly thing with new leaves but the original leaves were dying and damaged so I removed them I have included a picture can someone please tell me what I’m doing wrong and what is wrong with my plants?
How many months of the year in moderate temperature Northern CA do The Original and BloomStruck hydrangeas bloom?
How do I trim to make them bloom more?

I planted my Endless Summer Hydrangea about 2 weeks ago and it did really well for the first week and now it’s becoming less and less healthy.
 When I planted the hydrangea the tag said it would tolerate full or partial sun, so I planted it an area that receives full sun for about 10 hours a day. I also put a small amount of the fertilizer into the hole. I have watered it well daily since i planted it. The leaves and blooms are turning purplish and then brown and dry. I trimmed the dead leaves and blooms off very carefully and it’s continuously declining.
I’m thinking I should transplant it to an area with more shade and am wondering if this would be ok to do if it’s done at a time of day that is not sunny and hot.
My Endless Summer hydrangea ‘The Original’ is placed in a location where it gets a lot of sun and by 6-7pm gets shade. How much sunlight can they handle?
Where are these hydrangeas sold? Can they be ordered on line?
I have a Hydrangea this is it’s 2nd year in a container, last year it had beautiful flowers, this year, its just getting taller no buds yet. From the top of the pot to the top of the plant it is about 30″ tall very full. What can I do to help it or should I have done something earlier? I did just give it plant food. Granulars and watered it.
About 3 weeks ago I planted summer crush hydrangeas in zone 5 in NE. Per you site and the tag it claims these plants can have full sun in zones 4-9. I planted these facing east and given the sun rise I believe they are getting about 8 hours of sun. Since it’s gotten a little warmer I’ve been noticing them drooping a little come the end of the sun time. They seem to re bound after they are in the shade and or I water, but I’m concerned since it will only get hotter here. Is this just b/c their are newly planted or should I be concerned I planted them in too much sun? Also, how much should I be watering them? Thanks
