Complete Care Guide
Bigleaf Hydrangea requires moderate care to thrive. Plant it in a location with morning sun and afternoon shade to protect its delicate blooms from harsh sunlight. The soil should be well-drained and rich in organic matter to retain moisture without becoming waterlogged. Regular watering is essential, especially during dry spells, to keep the soil consistently moist but not soggy. Mulching around the base helps conserve moisture and regulate soil temperature. Fertilize in early spring with a balanced, slow-release fertilizer to encourage healthy growth and abundant flowering. Prune after flowering to remove spent blooms and shape the shrub; avoid heavy pruning in late fall or winter as it blooms on old wood. Protect the plant from deer and rabbits, as it is occasionally damaged by these animals. In colder zones, provide winter protection by applying mulch around the root zone to prevent frost damage. With proper care, Bigleaf Hydrangea will reward gardeners with vibrant blooms and lush foliage throughout the growing season.
