Answer: If it bloomed before but hasn't bloomed since you moved it, I don't think your hydrangea is getting enough sunshine. It needs at least 4 hours of morning sun in order to bloom well. You might consider moving it to a sunnier spot. Hydrangeas bloom on new shoots which develop on old wood. It's too late in the season for it to bloom, but you can try cutting it back now so there will be lots of old wood for new shoots to develop on next spring. Don't fertilize your plant - too much nitrogen fertilizer can result in lots of lush, green growth but at the expense of flowers.
Best wishes with your hydrangea.
