I have several hydrangeas in large pots on my shaded patio(Nikko Blue, Blushing Bride, Burning Embers, and Big Daddy). I bought all of them in May or so from either HD or Lowes. I wonder if they are getting enough sun as they are not blooming much. There is some morning sun and then periodic filtered sun later in the day (through very tall trees). When I brought the Nikko home it had one bloom, which has come and gone, but no more. However, the Nikko seems to wilt quite a bit, but perks up after I water it everyday. Does it need both more sun and more water? The others are Blushing Bride (one small bloom with no wilting) and one Glowing Embers (one small bloom and no wilting) and Big Daddy with no new blooms either. These do not seem to need as much water, but do they need more sun to bloom more?

The Nikko gets Miracle Grow for Acid Loving Plants and the others get just regular MG.

I live in Charleston, SC and it is brutally hot and humid here at times. I have a Forever and Ever Double Pink in more sun and it has bloomed better. Should any of the 4 that are on the shaded patio be moved to a sunnier spot?

The plants appear healthy. They just do not have many blooms. Because I just got them in May, I have no idea about previous pruning. Please help as I want beautiful blooms! Someone suggested a bloom booster type of Miracle Grow to force more blooms, but I don't know what that would do to the color of my Nikko blue. Any gardners familiar with the heat and humidity of Charleston, SC as well as hydrangeas in pots? I need help with getting them to bloom more. Thanks! nattycat :)
