Why are My Blue Hydrangeas Turning Purple

Fact Checked By | Post Updated On:

Have you ever wondered why your blue hydrangeas are turning purple? There are a few reasons why this may be happening. First, it could be due to the pH of your soil.

If the soil is too alkaline, it can cause the flowers to turn purple. You can test the pH of your soil with a simple test kit from your local nursery or garden center. Second, it could be because of the way you’re watering your plants.

If you’re using hard water that contains high levels of minerals, it can also cause the flowers to turn purple. To avoid this, use distilled water or rainwater instead. Finally, if you live in an area with high levels of atmospheric pollution, that could also be causing the flowers to turn purple.

If you have ever wondered why your blue hydrangeas are turning purple, the answer is simple. It is because of a chemical reaction that occurs when aluminum sulfate is added to the soil. This reaction causes the blue hydrangeas to turn purple.

How to change the color of hydrangea flowers.

Why Has My Blue Hydrangea Turned Purple?

If you have a blue hydrangea that has suddenly turned purple, don’t fret! This is actually a fairly common occurrence and there are several possible explanations. One possibility is that your soil is too alkaline.

Hydrangeas prefer slightly acidic soils, so if yours is on the alkaline side, it could be causing the flowers to change color. You can test your soil’s pH level with a home testing kit and amend it accordingly. Another possibility is that the plant isn’t getting enough water.

wilting leaves or dry soil are signs that your plant needs more H2O. Make sure to give it a good soak about once a week (depending on your climate) and keep an eye on the moisture level of the soil. Finally, another reason why your blue hydrangea might be turning purple could be because of too much sun exposure.

These plants do best in partial shade, so if yours is in full sun all day long, it could be causing the flower color to change. Move it to a spot where it will get some afternoon shade and see if that makes a difference.

How Do You Keep Blue Hydrangeas Blue?

There are a few things you can do to keep blue hydrangeas looking blue. One is to use an aluminum sulfate fertilizer. This will help lower the pH of the soil and make it more acidic, which in turn will keep the flowers from turning pink.

Another method is to grow the plants in full sun. The sun helps prevent the flowers from turning pink as well. Finally, you can also add some organic matter to the soil, such as pine needles or compost, which will also help keep the soil acidic and the flowers blue.

How Do I Make My Hydrangeas Blue Again?

If your hydrangeas are not blue, don’t worry! There are a few things you can do to encourage blue blooms. First, make sure you are using a high-quality fertilizer that has plenty of phosphorus.

This element is key in encouraging blue flowers. You can also try adding aluminum sulfate to the soil around your plants. This will acidify the soil and promote blue flowers.

Lastly, make sure you are watering your plants regularly and deeply; hydrangeas need lots of water to thrive. With a little care, you should see beautiful blue blooms on your plants in no time!

Do Blue Hydrangeas Stay Blue?

There are a lot of variables when it comes to the question of whether or not blue hydrangeas will stay blue. The type of soil, the pH level of the soil, and even the amount of sunlight can all affect the flower’s color. In general, however, blue hydrangeas will stay true to their color if they are grown in acidic soil with a pH level below 7.0.

If the soil is neutral or alkaline, however, the flowers may turn pink or purple. To keep your hydrangeas blue, make sure to fertilize them with an acidic fertilizer and water them regularly. You can also add aluminum sulfate to the soil to help lower the pH level and keep the flowers blue.

Blue And Purple Hydrangea Meaning

If you’re looking for a way to show off your true colors, look no further than the blue and purple hydrangea. This bold flower is often associated with royalty and luxury, making it the perfect way to add a touch of elegance to any occasion. But what does the blue and purple hydrangea meaning represent?

Here’s everything you need to know about this striking bloom. The blue and purple hydrangea has long been associated with royalty and luxury. In fact, the word “hydrangea” comes from the Greek words for “water” and “jug”, which is fitting given that these blooms are often used as centerpieces or decorations in lavish settings.

The rich color palette of blue and purple hydrangeas also make them ideal gifts for special occasions like weddings, anniversaries, or birthdays. If you’re looking for a gift that will truly impress, go with a bouquet of blue and purple hydrangeas. While the blue and purple hydrangea meaning is often associated with wealth and prestige, these flowers can also be used to convey other messages.

For example, the deep blue hue of these blossoms can symbolize depth of feeling or sincerity, while lavender hues convey purity or innocence.

Hydrangea Leaves Turning Purple

If you’re noticing that the leaves on your hydrangea are turning purple, don’t worry – this is perfectly normal! Here’s a quick explanation of why this happens: The vast majority of hydrangeas have what’s called an “acidic soil reaction.”

This means that when they take up water through their roots, they also absorb small amounts of aluminum from the soil. And it just so happens that aluminum is what gives hydrangea leaves their beautiful blue or purple coloration! However, if the pH of the soil is too high (meaning it’s more alkaline), then the aluminum isn’t able to be absorbed by the plant.

As a result, you end up with green leaves instead. So if you want to keep those gorgeous purple hues in your hydrangea, make sure to monitor the pH of your soil and keep it slightly acidic – around 5.5 or 6 should do the trick!


If you have blue hydrangeas and they are turning purple, it could be due to a number of reasons. The most common reason is that the pH of the soil is too high. This can be easily fixed by adding some sulfur to the soil.

Another possibility is that the plant is not getting enough sunlight. Make sure to give your hydrangeas at least six hours of direct sunlight each day. Finally, it could also be that the plant is stressed from too much heat or too little water.

If you think this might be the case, try moving the plant to a cooler location or increasing its watering schedule.
