A lot of people love the look of hydrangeas, but are concerned when their leaves start to turn purple. There are a few things that can cause this, but don’t worry – it’s usually not a sign that your plant is sick. Here are a few potential reasons why your hydrangea leaves might be turning purple:
- The weather is cooling off. As the weather starts to cool down in the fall, the chlorophyll in the leaves starts to break down. This can cause the leaves to turn purple, red, or brown.
- The soil is too alkaline. If the soil is too alkaline, it can cause the leaves to turn purple. You can test the soil with a pH test kit to see if it’s too alkaline. If it is, you can add some sulfur to the soil to lower the pH.
- The plant is getting too much sun. If the plant is getting too much sun, the leaves can turn purple. This is more likely to happen if the plant is in a sunny spot during the summer months. You can try moving the plant to a shadier spot to see if the leaves start to turn blue again.
- The plant is stressed. Sometimes, stress can cause the leaves to turn purple. This can be from things like drought, pests, or disease. If you think this might be the case, check the plant for signs of stress and try to address the problem.
- It’s a genetic trait. Some hydrangeas are bred to have purple leaves. So, if your plant has purple leaves, it might just be because that’s the way it’s supposed to look.
It’s natural for hydrangea leaves to turn purple as the weather cools down in the fall, but some people want to keep their plants looking green.

What causes hydrangea leaves to turn purple
It’s the time of year when gardeners start to notice hydrangea leaves turning purple. So what causes this phenomenon and is it something to worry about? Let’s explore the answers to these questions.
The most common reason for hydrangea leaves turning purple is an excess of aluminum in the soil. This can be caused by using fertilizers that are high in aluminum, or by acid rain which leaches the aluminum from the soil.
If you have recently changed your fertilizer or if there has been a change in your local climate, this may be the cause of your plant’s discoloration.
However, it is important to note that not all cases of purple leaves are due to too much aluminum. In some varieties of hydrangeas, the leaves are naturally purple or red. So if you’re not sure what variety you have, this may be the explanation for your plant’s color change.
In most cases, there is no need to worry about your hydrangea’s leaves turning purple. However, if you think that too much aluminum might be the cause, you can try to correct the problem by adding lime to your soil. This will help to neutralize the acidity and raise the pH level, making it less likely for aluminum to be leached from the soil.
Of course, if you’re unsure of what’s causing your plant’s leaves to turn purple, it’s always a good idea to consult with a local nursery or an expert on the subject. They will be able to give you specific advice based on your individual plant and situation.
So there you have it, a few possible explanations for why your hydrangea’s leaves might be turning purple. In most cases, there is no cause for concern, but if you think that aluminum might be the culprit, you can take steps to correct the problem. As always, if you’re unsure of what’s going on with your plant, it’s best to consult with a professional.
