Blossoming Questions

I am in Missoula, Montana Zone 4-6. What variety of hydrangea would be best for me to purchase for a pot on my patio that gets plenty of sun?

If I trim my Endless Summer^® hydrangea back to the first bud on last year’s growth, will I get this year’s bloom? Can I just prune back to shape the plant?

Why doesn’t my hydrangea bush get any flowers?

Do next years blossoms come on new or old growth?

Pleeeeease help. SOS…
I need help because my hydrangeas continue to decline. It looks like they are spiraling just down now. I have attached today’s picture. They’ve been in morning sun/pm shade, moist, and last week I did add 1/2 oz of bone meal and 1/2 oz de-acidifier to soil. Thoroughly wet it afterwards. I’m trying not to give up…. help please.

Help! I recently planted two Summer Crush hydrangeas and they are not looking good, I’m worried they are going to die. They started off wilting during the day but would come back at night, now they aren’t coming back at all. I’ve watered them daily for the most part, not drenching them. It does get quite a bit of sun until about 2:30pm. Any help would be appreciated!

I just bought 2 Bloomstruck Hydrangeas. I know the tag says not to prune. However, should I cut off the spent blooms?

Why are my blue blooms turning white?

Do I have to cut off the expired blooms on my Easy Elegance rose bush?

I just bought some BloomStruck Endless Summer hydrangeas. I always thought hydrangeas were blue or pink regards to the soils Ph. Now will the BloomStruck hydrangeas always be a purple color or will they turn blue or pink if I don’t have the correct Ph?
