Answer: Hi John,

Yates recently released a liquid correction range of which Aluminium Sulfate is one. It can be applied to your hyrangeas to produce and deepen blue coloured flowers. You will need to apply this product every 3 – 4 weeks. This product will help with reducing soil pH, and at the same time supply the aluminium necessary for blue flowers.

You will find this product at your local hardware store or nursery.
