How to Change Hydrangea Color

As you can see from the questions asked and answered above, there are many different ways that you can change the coloring of a hydrangea.

But when it comes down to it, what really makes the flowers change colors? Is it the sun, the additions, or just a stroke of good luck?

Actually, it has to do with the pH balance of the soil in and around the flowers.

Start by Testing Your Soil’s PH

Use a test kit to test the PH of your soil.

If you have soil that has a pH balance of 5.5, you’re going to find that your hydrangeas bloom in the color of blue and you will get purple with a PH of 5.5 to 6.5.

However, once you have soil with a pH balance of 7.0, you’ll start to see them bloom in bright reds and pinks!

And the good news? You have the ability to control the pH balance of the soil by adding in different things to change the coloring.

How to Change Hydrangea Color to Pink

Make hydrangeas pink

To change hydrangea color from blue to pink, you will need to reduce the aluminum content of the soil to make it alkaline.

The best way to achieve that is by using garden lime to increase the PH of the soil. Use 1/2 cup of garden lime for every 10 square feet.

You will need to apply the garden lime every 3-4 weeks throughout the growing season to keep the hydrangeas blooming pink.

How to Turn Hydrangeas Blue

Turn hydrangeas blue

If you have pink hydrangeas (due to alkaline soil) and want to turn it blue, the simplest way to do that is by making the soil acidic, which requires increasing the aluminum content of the soil.

You can achieve this by adding aluminum sulfate, compost, coffee grounds and pine needles to the soil.

Note that the soil isn’t going to turn acidic overnight. So your hydrangeas are not going to turn blue overnight. It is a gradual process and can take up to a year to see your hydrangea turn blue.

You need to continue adding aluminum sulfate to the soil throughout the growing season to keep your hydrangea blue. Add 4 tbs of aluminum sulfate to 1 gallon of water and soak around the plant’s base every 2-4 weeks.

How to Change the Color of Hydrangeas to Purple

Why are my hydrangea flowers turning brown?

If you notice that your flowers are turning brown, this isn’t a color that you should want!

In fact, brown blooms on your hydrangea plant is an indicator that you’re needing to give them more water. This is a sign that they’re wilting and need to be given a boost.

What does an overwatered hydrangea look like?

This is where it gets tricky. If you underwater OR overwater, you’re going to notice that the leaves are turning brown.

This means that you’ll have to really pay attention to your plant and the soil surrounding your plant so that you know what action you need to take.

Just because you see brown leaves doesn’t mean that your plants are lacking water. It could actually mean that they have too much water instead!
