Jesse,,try to dig as large a planting hole as possible ....break,up that rocky subsoil if you can. Dove took my words....she always does ..ha ha....but yes, the name tells,you it needs water. you probably cannot over water it in summer.
Limelight is a different sort of hydrangea needing slightly less water I think.
rather than splash out on buying more hydrangeas concentrate on that planting hole. Good bulky compost is preferable to too much fertiliser I think.
Good luck Jesse
