I’ve heard that you can change the colors of hydrangeas by using baking soda. Do you know about this?
If you can lower or raise the acidity of your soil by adding things to your soil you can try to change the color of your hydrangeas. Here's some info for you!
It's the pH balance. Baking Soda and coffee grounds are two of the items that can effect the color of your flowers. The article posted by Gk is a really good one.
Hi Betsy: My neighbour uses coffee grounds to change the colour of hers. Good luck
Here's another article to research how to have blue hydrangeas. Wishing you the best.
Hello! The pH of the soil that determines the flower color—specifically, whether or not the hydrangeas are taking up aluminum from the soil. If the flowers are pink, the plant is getting aluminum. If they’re blue, it isn’t.
You can control the color by altering the pH.
Soil testing can determine your pH.
Acidic soil, with a pH lower than 6.0, yields bluish hydrangea blooms. Alkaline soil, with a pH above 7.0, promotes pinks and reds.
pH between 6 and 7, the blooms turn purple or bluish-pink.
To lower your soil pH, add garden sulfur or aluminum sulfate to your soil.
To raise the soil pH, use ground lime.
Hydrangeas are some of my favorite flowering shrubs—- best of luck with your gardening adventures!
Here is a very informative link for you on Hydrangeas and their colors:
Generally speaking, acidic soil, with a pH lower than 6.0, yields blue or lavender-blue hydrangea blooms. Alkaline soil, with a pH above 7.0, promotes pinks and reds. With a pH between 6 and 7, the blooms turn purple or bluish-pink. To lower your pH, add garden sulfur or aluminum sulfate to your soil.
You can change the pH of the soil. More acidic soils will be blue blooms - 6.5 or higher will give you pink blooms. If you add baking soda, you will make it more basic. If you want pink blossoms, then add it. Otherwise get an acidic fertilizer at a garden store for blue blooms.
Yes you put the baking soda around the base of the plant
