• Ineffectiveness of hydrangea colourant

    Last year I used hydrangea colourant to turn my deep pink mophead
    hydrangea blue. I diluted it in accordance with the instructions and
    applied it once a week from early May to early July. To my
    disappointment the flowers turned out mauve-purple rather than blue.

    I tried again this year in the belief it would take another season to
    make the soil acidic. But this summer the flowers were actually pinker
    than last year!

    Where did I go wrong? The only thing I can think of is that I didn't
    fork around the roots before applying the colourant.
