Tips for Achieving Blue Blooms

The intensity of blue in hydrangea blooms depends largely on your soil’s pH. For the best blue shades, amend your soil with aluminium sulfate and maintain acidity with organic mulches like pine needles or peat moss. Regular feeding and watering throughout the growing season also ensure lush growth and vivid colour.
