Blossoming Questions

Thinking of putting some beautiful hydrangeas in my home in Zone 7a. Do they need full sun or part?
I planted 2 Easy Elegance® roses this spring, but I’ve seen no signs of new growth. They are in full sun, and I have tried to keep them well watered. Would cutting them back a bit prompt new growth?
I am wondering how fast the Linebacker Distylium grows. I am full sun, zone 7a. I am having trouble finding it’s growth rate online
Purchased First Editions Vanilla Strawberry hydrangea tree almost 2 weeks ago. Planted it on the ground, full sun (morning)area. Now, the bottom leaves are turning yellow. I make sure that soil doesn’t get dry. What to do?
About a week ago I planted one midnight magic crape myrtle and one lunar magic crape myrtle in my backyard. They get full sunlight, I’ve watered twice but the leaves are starting to wilt, they look like they are dying. Is there anything specific I can do to prevent them from dying
The Summer Crush label says full sun but videos say not full sun. Can they be full sun?

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.
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
