last year I bought a beautiful specimen from the supermarket. It was mostly green, with a tinge of pink, and the shape was quite different, being like a two tier mushroom sort of shape. This year it is still in potting mix, but has been repotted to a larger pot and is now pale pink, with a tiny hint of green. How can I get it back to it's original colour. It's too dark to take a good photo now, but I might do that tomorrow. Unfortunately I don't have a good one of it from last year either. darn it! and that's darn, not dam
This statement is definitely not true for most hydrangea. Most of them are white, changing to greenish or pinkish colors when they age. It is only the H. macrophylla and H. serrata that show blue or pink depending on soil conditions. H. paniculata and H. arboescens will not change color with a change in pH.
The change of color between blue and pink does not happen because of a change in pH. If you have soil that contains no aluminum, you will never have blue flowers, no matter what the pH is. It is the aluminum in the soil that makes the flower blue.
Excess phosphorus will also tie up aluminum making it unavailable to plants

And iron that turns them pink - a few rusty nails was my Grandmother's trick. I dosed some of mine with Hydrangea Blue this year, and have some lovely lavenders lol.
this is the colour now, the green bits were the predominant colour last year, ALL season, not just as it was fading, in fact it didn't fade other than to gradually go brown and it was cut off. The amount of green that can be seen this year, is equal to the amount of pink there was last year.
Any suggestions, comments. It's a pretty plant as it is, but I'd like it as it was

If it was my hydrangea i would add some Aluminium sulphate to the soil. Yates is one brand of this product, if you go to Bunnings, mitre10 they should have it. You probably wont get the results you want this year as it is already flowering, but by next year it should have adjusted the pH and aluminium levels more to where you want them.

Thank you dibble, I'll try that. By then it will be big enough totake cuttings off it, so I can play around with it a little
SO! Can anyone tell me why I had four flowering shrubs (hydrangeas) last year, and this year only three of them. The were all young plans, so I don't think it would be that one of them only flowers every second year, or some such reassoning.

Could the one that is not flowering (assuming all leaf growth) have got lots more nitrogen fertiliser than the other 3? Extra nitrogen encourages leaf growth rather than flowers. Potash (pottasium sulphate?) is good for encouraging flowers and fruits on plants.

hydrangeas do best in the shade

I find that the heat of the sun, turns white or green hydrangeas pink. best grown in shade or dappled shade.

Yup, I'd be putting that one in the shade if you want more green.

It gets more shade than the others, but last year was in my covered patio area, and stayed green, will put it there next year.

they are all in pots, repotted with the same mixture at the beginning of the season
