Does anybody know of a simple, inexpensive way to turn the colour of hydrangeas to blue please?

It all depends on your soil type. Look at your neighbours see what colour they have, and that is what yours will turn out like - they can change colour over years too, due to change in weather conditions and air pollution that lands on your soil.

but, if you have a load of 1p's or lots of odds and bods of copper piping (the sort a gas fitter would use) bury them under the plant.

you can also, use ericeacous (sp) soil, usually has written on it for azaleas.

they are beast unto them selves hydrangeas.

I know they're pink or blue, depending on the soil type, so why is it that sometimes you see a plant with some of each colour? It doesn't make sense to me.

You need an acid soil for blue hydrangeas and you can buy a ‘blueing agent’ which contains Aluminium sulphate to give the hydrangeas a blue colour if your soil is not acid enough.

Essex Girl, Don't know how you get both colours on the one bush!! Just lucky, i guess!

I think copper sulphate works too.
