Hydrangeas from blue to pink - what do I need to get them to change to lavender/pink.?

Answer 1

My hydrangeas are supposed to be blue. It is called, Nikko Blue, but they are getting pink flowers because of the soil they are in. If the soil is sweet, means alkaline, the flower will be pink and if the soil is acidic, the flower will be blue. Try adding a small amount of lime(Be careful when you do it. Wear gloves and don't inhale it.). Maybe your hydrangeas will become pink. I can't guarantee the lavendar/pink color, though. I don't think you can control that much.

Answer 2

You can alter the color of your hydrangeas by changing the pH of the soil surrounding them. Alkaline soil will make the flowers pinker; acid soil will make them bluer. But if you want a pink hydrangea, you should buy a variety which was bred to be pink. Tampering with the soil pH to accommodate one plant in the garden could have repercussions for the entire garden.

the links on the left are great reading, too....

getting the soil just right to get lavender will be tough... you'll see a few blooms in a year that will show lavender color, but they'll want to go one way or the other, mostly.... it's a fine experiment, tho.... and, it's easier to 'play' with a plant in a container than in the soil..... maybe get another to play with?...
