Snowhill Hydrangea Growing and Maintenance Tips
All hydrangea naturally undergo some colour change to their flowers as they age. Adjusting the pH balance of the soil (and the addition of aluminium sulphate) can change the flower colour from pink to blue in some cultivars. Most cultivars thrive in full sun to partial shade as long as they have adequate moisture and a rich, well-drained soil.
