Manutec | Hydrangea Blueing 500g

Manutec Hydrangea Blueing Fertiliser promotes healthy growth of Blue Hydrangeas and enhances size and colour of blue flowers.

The fertiliser is rich in nitrogen and potassium.

As soil pH determines sepal colour in hydrangeas, it is most important that pH of the soil or potting media is determined and adjusted prior to the growing period. For plants to produce blue sepals it is important that the soil pH is maintained around slightly acidic pH of 5.5 to 6.0/

pH can be lowered by adding Manutec Sulphur to the media and maintained by the regular use of this solution.
