Hydrangea need acidic soil, below ph6. If the soil is alkaline (ph above 7) then the flowers will turn pink. Don't expect this to happen quickly. It may take an entire season.

Does baking soda in the soil keep hydrangeas blue?
No, it will make them pink; baking soda is alkaline, so the pH will increase. If you want to make them blue, you should put rusty nails in the soil. In an acidic soil (pH near 6), you'll get blue flowers.
What colour do hydrangeas start off as?
It depends on the variety of Hydrangea although soil acidity or alkalinity will alter the shading and colour. Generally, acidic soil produces blue or lavender-blue hydrangeas and alkaline soil produces pinks and reds.
Will coffee grounds keep hydrangeas blue?
No, coffee grounds do not keep hydrangeas blue on their own.Specifically, the blue blooms on the hydrangea are the result of the plant being able to take aluminum from the soil into the roots. Aluminum has to be in soluble form for plant root intake. A soil that is too dry impedes adequate aluminum intake and therefore proper blue blossoming. Coffee grounds work to retain moisture in soil.
