Blossoming Questions

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?
I purchased a JetStream Hydrangea. I want to set up a water irrigation system. How often should it be watered, how many times a week and for how long? It is planted in central South Carolina.

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.
I have 2 rose bushes that I need to plant. I live in Colorado and have a north facing front and south facing back. Where is the best place to plant them and how?
On the west side of my house there is about a 6ft wide path between my house and the fence. We are putting in a 4ft wide interlock walkway and there will be a foot and a half space between the house to the interlock that will be soil and we’d like to plant something. Zone 5. Is this enough room to put any type of hydrangea? I love the colors.
I’ve had my hydrangea for 4 years and no blooms. It looks healthy not sure what I’m doing wrong.
How come my hydrangea doesn’t flower?
