Moist but well drained

North American wild hydrangea · Hydrangea arborescens
Smooth hydrangea is known for its resilience and low maintenance, making it generally easy to care for. It flourishes in partial to full sun, preferring moist, well-draining soil. Special attention should be given to adequate watering, especially during dry spells, and annual pruning to encourage robust growth and blooms. Fertilization can support healthier flowering but should be applied judiciously to avoid overstimulation.
