Planting & Care

Annabelle Hydrangea shrubs grow best in well-drained soil with morning sun and afternoon shade, especially in warmer regions. Dig a hole about twice as wide as the root ball and plant at the same depth it was growing in the container. Water regularly during the first growing season to help establish a strong root system. Because this hydrangea blooms on new growth, light winter pruning helps maintain shape while encouraging abundant blooms the following season.
