Hi all,
I split and transplanted a Hydrangea two years ago, it did not
flower last year, but does have flower buds forming this year.

Is there anything I can dress the ground around them to get blue
flowers please?

Mick.

You need to get the soil below pH 7.0

A very easy way is water it daily with a very weak acid solution. A
bottle of vinegar in 5 gallons of water is about the right strength.
If you drink lots of real coffee always put the used grounds on the
soil.
