Hydrangea Colourant

If you are looking to change your pink hydrangeas blue, then Hydrangea Colourant is ideal.

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.

Best results are obtained with plants growing in acid soil, but if your soil is alkaline the proportions should be doubled.

• 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.

Always keep out of reach of children and wear protective gloves and eye protection where possible during use.

Sizes available:

• 250g

• 500g

Hydrangeas growing in the presence of iron or aluminium salts will tend to change colour and produce blue flowers. Varieties naturally pale pink tend to blue best, the darker pink varieties turning to mauve/ blue. Best results are obtained with plants growing in acid soil. If the soil is alkaline the following proportions should be doubled.

Pot or container grown hydrangeas

Mix Hydrangea Colourant with the soil when potting in the proportion of one part to thirty parts of potting soil e.g. 250g in 7.5 litres. During growth water weekly with 30g Colourant per 5 litres of water. Hydrangea Colourant is most readily dissolved first in a little hot water.

Outdoor grown hydrangeas

On planting, mix Hydrangea Colourant with soil in which the root system will develop, in the proportion of one part Colourant to thirty parts soil e.g. 250g in 7.5 litres. Subsequently, water weekly during the growing season at a rate of 30g per 5 litres of water. Apply to the area of soil covered by the bush itself, thoroughly wetting the soil surface. The colour of other plants can be intensified by treating with Hydrangea Colourant in the same manner.
