Care Guide
Watering
Keep the soil consistently moist. Hydrangeas need about 2.5 cm of water per week. Water deeply at the base to encourage deep root growth.

Soil and Fertilizer
Provide rich, well-draining organic soil. Apply a balanced slow-release fertilizer in early spring.
Pruning
Prune immediately after flowering in late summer for old-wood bloomers, or in early spring for new-wood varieties.
Propagation Methods
