Just a little blue...........

I adore the large hydrangea bushes here at the chateau. They were planted many years ago by Madame Guerin who lived here. They have always been the most amazing rich pink.......

Until this year when some have a blue tinge.

Why is that?

  1. I'm not an expert, but my grandfather told me (years ago, obviously!) that normally hydrangea change from pink to blue due to there being aluminium in the soil, but if they have been there for some time, as you say yours have, then there are two other possible causes:
    1. you have used a fertilizer that is low in phosphorous and high in potassium, or
    2. you may have had building work carried out nearby, and the concrete and/or plasters used are leeching into the soil
    There is of course one further option, and that is that the Fairies in your garden just prefer them that way! ;)

    1. Hi Len
      There has been so much building here since we moved in that it is very possible. Or....we gravelled the drive around them and that could be it....or there again it may be the fairies

  2. Hi Shirley its to do with the soil this link tells you how to change them

    But then again who knows what those French Fairies get up to? in your garden.
