Directions for use
Hydrangeas growing in the presence of iron or aluminium salts will tend to change colour and produce blue flowers. Varieties which are naturally pale pink tend to blue best, the darker pink varieties turning to mauve/blue. Best results are seen with plants growing in acid soil. If the soil is alkaline measurements shown on the packaging need to 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. During growth water weekly with 30g 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 to thirty parts soil. 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, throroughly wetting the soil surface. The colour of other plants can be intensified by treating with Hydrangea Colourant in the same manner.
