Colouring blue 'drangeas
 

I have a hydrangea which I am fairly certain is supposed to be blue.

What is the best time of year to apply colourant you can buy in garden
centres (or Miracid) ? Now or in late winter/ spring? I'm guessing it
will got to waste if I use it now.

Cheers.

Hallo

I've always heard that you need to do it now as the hydrangea makes its new
flowers or buds or whatever in the autumn

I saw some hydrangeas in western Cornwall that were turquoise and a few pale
green ones, could that be due to the copper / tin in the area? I have never
seen them those colours before.

I've seen these coloured varieties in garden centres and it seems that that's
just the colour they are. They may change their colouring somewhat though if
they have the wrong conditions, but it's not something I have personal
experience of.

Possible I suppose, but I think unlikely. Although as you say, copper
and tin were extensively mined in Cornwall in the past, the deposits
were quite localised and large areas of the county are nowhere near
mining. I'd be more inclined to think it was the variety. A topic for
some interesting experiments though, although bear in mind that I
believe copper tends to be toxic to plants above a pretty low
concentration. Most of the waste tips on the copper mines are still
barren after 100 years or more, although they do contain a cocktail of
poisons.

We have one down the road from us: it's an eery sort of place - all red
sand with straggling birch trees and occasional heather. Nothing grows
in the stream running through it. Quite different from the dense oak
woodland along the rest of the valley, all of it grown up since the
mining stopped.

I only have one hydrangea: was pink, now blue though judicious
application of rusty nails. Turns a weird sort of purple, then greenish
as the flowers age. Don't think there is much copper in the soil
directly here though: the mine under us was for arsenic, and a long,
long way down.

They used to mine round here for gold long ago, then later copper, then
arsenic. Now our only local mine is a gravel quarry - and apparently
they are running out of gravel!

Surely, we must be at the end of the mining, when the gravel runs out!

Sounds like it!

Thank you all for your opinions, might be worth an experiment with a very
small quantity as Chris suggested, just to see if anything happens.
