Thanks for the question.  Here are some general care tips to help you.

Hydrangea care

Location: The ideal spot for a hydrangea is in morning sun and some afternoon shade. Filtered sun also will work. Flower count declines over the years in deep shade, and eventually your plant may not bloom. Oakleaf hydrangeas may be more sun-tolerant.

Soil: Hydrangeas perform best in a well-draining soil rich in organic matter. Avoid planting in highly sandy or heavy clay soils. Amend either soil type with compost to improve texture, soil retention and/or drainage.

Nutrients: Fertilize hydrangeas during the early to middle growing season. Use a slow-release or organic fertilizer.

Water: Keep soil moist, especially during summer. Make sure the soil drains. Mulch to conserve soil moisture.

No blooms? Hydrangeas may flower poorly or not at all in complete shade. Improper pruning also results in no blooms. Avoid late-winter pruning when traditional mopheads and oakleafs are setting buds on old wood. Prune after the shrubs flower.
