Blossoming Questions

I have 3 of the Original Endless Summer hydrangeas planted. 2 of the plants have blooms that have turned brown and completely dried out. Should I prune these off and how should I do that?

I have Summer Crush hydrangea that is 24-36 inches. When it first flowers, they turned out a nice pink, just a month they changed like something is wrong. Any suggestions?

When I cut off a bloom where should I make the cut on the stem?

Should my Easy Elegance shrub be pruned in the fall?

Why do my blooms look burnt?

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.

When and what is the best way to remove Hydrangea blooms once they are turning brown, or cycled through their color?

Is there any pruning to be done after the flowers die off?

Should I cut off dried up blooms to promote more flowers?

I live in Maryland (Zone 6) its mid July and my blooms are fading, is this just the natural progression of life or will my plants re-bloom. They are getting the proper amount of water and I just lightly fertilized. Anything else I can do?
