Blossoming Questions

Where is the best place to plant my endless summer. I’m thinking east or south? And little more detail like 6-8 hours of morning sun?
Where on the endless summer stem do I cut the blooms when I want to use in vases or because the bloom is spent and needs to be removed?
I purchased 1 Summer Crush which came with lots of old dead sticks. After 3 weeks of planting, I can see some new leaves growing out but very tiny. I just cut al dead sticks, I’m not sure it can grow bigger and bloom in the first year? I just feel it’s not growing.
How do I prune once the flowers turn brown during summer?
My endless summer hydrangea is looking a little bit wilted. Some of the flower buds are bending down. I felt the soil and it is moist. We had a thunderstorm last night with strong wind for about 1-2 hours. Could that be the reason why? Is there anything I should do at this point? Thank you and any insight is appreciated:)

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?
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
How can I get my hydrangea plant to grow larger? Every year the plant died back and new growth are coming from the base when summer arrives. All the branches left from previous are all dead and did not have any new growth, and pruning did not seems to help.
Where can I find the purple lace endless summer hydrangea I really want one.
