Keeping Blue Hydrangea, Blue
If you are looking to keep your Hydrangeas blue or even ones that have turned pink already then the Hydrangea colourant is what you need.
Hydrangeas that grow where iron or aluminium salts are present tend to change colour and produce blue flowers. Depending on the variety, pale pink hydrangeas will turn blue best with darker pink varieties turning to mauve or blue.
• Used for both pot grown hydrangeas and those grown outdoors
• Readily dissolved in a little hot water
• Mixed with soil for best results
For both potted hydrangeas and those grown outside, simply mix Hydrangea Colourant with the soil in which the root system will develop.
After establishment, dilute the Hydrangea Colourant as directed and water weekly during growth.
