Q.Blue hydrangea blooms turning white/green/brown
I bought a blue hydrangea that I think is Endless Summer (I don’t remember what the tag said), the blooms are turning a brownish color. The leaves are fine and green, though the bush had some sun damage on one bunch of blooms when I bought it, but now the rest are starting to tuen green-brown. I try to keep the soil moist and know it may need some nutrients, I’m just not sure how to fix it. How can I get it vibrant and blue again?

It looks to me that the blooms are simply fading, the fate of all flower blossoms. The good news is that Endless Summer is a repeat bloomer; when the flowers are no longer attractive, cut them off. Here is a good growing guide including pH info: http://www.endlesssummerblooms.com/design-and-grow/planting-and-care
