Red Hydrangea

I love really blue hydrangeas .
You can add dilute vinegar to the soil to turn it acidic , but don't splash it on the leaves . It will damage them .
Or buy some colourant on line for about £6 .

We used to call it blueing powder .
Reminds me of the blue bags in the wash !

we bought a blue hydrangea last year and this first year for flowers it is red, am disappointed.
sorry, I have nothing useful to add about them though, our other pink ones have to thrive on their own which they seem to do.

Mine is the same colour as Maw's and was in a huge container but, after 10 years of huge flowers each summer, it was getting decidedly pot bound and so, last autumn I emptied it, gave it a good pruning back and potted it into an even bigger container. I've got loads of healthy growth this summer but not one single flower. I'm hoping for a better performance next year.

I wish I hadn’t seen that ? it’s been an awful year for mine.
One actually bloody died.

Gosh Maw - your hydrangeas are magnificent !

Mine are about 35 years old and planted out in the garden .
They came from another house so I'm not sure of their true age .
I had to move them about two years ago as they were frying in the hot sun .
I noticed that the garden had definitely warmed up .

I don't really do anything fancy with them - just water .
We have used a colourant to enhance their blueness before ..

Next years blooms may be sacrificed if you prune this year. If you are attempting to completely reshape the bush it might be worth it, otherwise I normally only prune about one third a year usually in the spring.
I would most certainly pot on in good quality compost, preferably loam. If you have a blue variety you need an ericacious compost and to keep the acidity up.

In my experience hydrangeas love water and sun.

I have never dealt with red hydrangeas but there will be lots of information on line.

I’m afraid I totally neglect mine, leaving the heads on to protect from frost and sloshing a bucket of kitchen floor washing water over them when I remember
It would be nice to know what I should be doing ??
