Blossoming Questions

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 bought a crabapple tree about two weeks ago and it has still to show any new growth. How long does it take to show any and how do I know it is actually healthy?
How do I dead head your roses? We just planted 3 of them. Thank you.
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 five Sapphire Surf Bluebeard plants, recently purchased and planted, are not greening fast. There appears to be dry or dead branches on many. The local retailer advised me to cut them down and allow them to grow new branches.
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?
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.
Should Easy Elegance roses have a trellis to climb?
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
