The colour of hydrangeas is affected by the pH of the soil - soils with a low pH (up to about 5.5) are acidic soils and will produce blue or purple flowers. Soils with a high pH (above 5.5) are more alkaline and flowers tend to become pink as the pH increases.
Many modern Hydrangeas are bred to be more inclined to either blue or pink, but in my experience they usually eventually revert to the above 'rule'.
Yes, hydrangeas prefer acidic soil with a pH level between 5.5 and 6.5. Acidic soil helps hydrangeas absorb nutrients effectively and promotes healthy growth and vibrant blooms. It is beneficial to amend the soil with organic matter or use acidic fertilizers to maintain the proper pH level for hydrangeas.
