Blossoming Questions

If the flowers are drooping to the ground, should I prop them up with supports?
My hydrangea blossoms are very large and are turning brownish and dropping some petals. Should I cut off the blossoms to encourage new blooms? Otherwise the plants appear healthy.
Is there any pruning to be done after the flowers die off?
Watering tips please!
Hi, I bought two ES twist n shout plants from Real Canadian Super store. Grown in similar conditions. One plant is blooming nicely and the other is not blooming at all. Wondering why.
Love hydrangeas but having a terrible time getting my shrubs to bloom They haven’t produced blooms in a few years I also bought some new ones this year and have them in containers I snipped the blooms off them when they faded and now the plants haven’t rebloomed. Would deadheading affect their ability to rebloom? I am considering leaving them in containers since I have had poor luck with my planted shrubs Any tips for containers? I desperately need some blooms!
Would you recommend deadheading grape lollipop garden phlox before pruning in fall? If so how would you deadhead the plant? Also what are your recommendations on how to prune the plant for the fall?
How and when do you prune hydrangeas?
Website says to fertilize in early spring or summer so does that mean you only fertilize one time? But it also says follow instructions on label, which mine says feed every 14 days. I bought the Scots company garden pro water soluble miracid acid loving plant food. So do I only do this once or do I feed every 14 days?
My Endless summers are doing well but have branches sticking up that don’t have leaves or buds. Should I cut these branches?
