If you have pink macrophylla hydrageas this soil amendment will help to turn the flowers blue. Hydragea macrophyllas change colour depending on the soil pH. When the soil is acidic the flowers will turn pink, if the soil is alkaline the flowers will turn blue. This amendment is meant to keep a vibrant blue.
