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. -- "I go online sometimes, but...everyone's spelling is really bad, and...it's depressing" |

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 Margaret "Ian Cundell" schreef in bericht ...

Colouring blue 'drangeas
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. Earnest "Margaret Paige" wrote in message ...

Earnest 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. Dave. |

Earnest 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. -- Chris E-mail: christopher[dot]hogg[at]virgin[dot]net |

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! Victoria |

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. Earnest |
