Tin can in a pot...

Is it really true, as a friend just told me, that if I want to keep my new hydrangea blue it will be enough to bury a tin can in the pot below the roots?

Iron helps hydrangea keep thier blue flower. My dad used to push rusty nails into the soil but I can see that the tin can would have the same effect.

yep, rusty nails will do the job.

Had no tins so hunted round for something rusty and found a long piece of metal which, usefully bent and stuck in the pot, is now also supporting the floppy giant hydrangea heads :-)

make sre its an iron can and not an aluminium one or it wont work. use a magnet if it sticks to the can it is iron. if not it is aluminium.
