• I’ve got a climbing hydrangea, the flowers are white. If I muck about with the ph of the soil and add some colourant could I get it to change colour?

  • Probably not.

    The blue ones should be able to be shifted to pink. But I'm pretty sure white ones are white.

    I'm gutted our climbing hydrangea died when I planted it. So odd. I should have just left it in its ugly shop pot.
