I live in new jersey and the soil has a sand base which does not retain water well. How much water should be given to the plants and where should they be planted sunny side of the house or partial shade?

Sandy soil can be a boon to gardeners, but you're right - it doesn't hold moisture well, so regular watering will be necessary. Hydrangeas are usually happy with one deep soaking per week; two if the weather is really hot. For best flowering give your hydrangea about 4 hours of morning sunshine but shelter from hot afternoon sun. While hydrangeas will tolerate afternoon sunshine the leaves tend to wilt in the summer. They usually recover overnight, but the wilting is unattractive so I avoid the problem by planting my hydrangeas in areas with morning sun and filtered afternoon shade. Best wishes with your hydrangea!
