We moved to a new house 18mths ago and the first summer the white hydrangeas were beautifully white, this last summer they have been more green. They had a good prune. What to I need to do to do to maintain the white colour?

Hi Hayley, apply sulphate of potash 2-3 times per year (now until late spring) and the colour should change back to white. Thanks, the Palmers team
