Title: Hydrangea colour
Post by: Baaaaaaaa on August 22, 2008, 02:04:40
I understand that you can change the colour of a Hydranger by added lime (for red) or by adding an aluminum/iron compound (for blue)


Has anyone tried either of these and how long does it take to have effect ?


How do you change the colour to white ?

Yes you can, it comes in a plastic container with a (of course) blue lid.  I can't remember what it's called, but it does work, you need to use it regularly throughout the season.

When I was a kid people used to bury old bed or bike frames in the soil :)

Strange but true :)

As we never had a garden full of junk, we were told to see the blacksmith and ask him for an old horse shoe to bury under the bush.

You can't.  You need to buy a white variety.  We have an enormous white variety h.paniculata.  It spreadss quite a bit, it you would like a plant.

Well a slight exaggeration. We nicked a horseshoe from the rag and bone mans old nag ;)

We had already flogged him the bedframes and old iron, and anything ese that was not nailed down ;D

I have often thought of submitting a design to Chelsea for a seventies council house garden.  Would not need many props just an old cortina and a mattress




I'll get my coat.

Not sure we're allowed to bury old beds, bike frames or even Cortinas in our allotment.

But I'll check ...








Err well, there's nothing that specifically prevents burying such items , so I guess it must be ok.  :P
