Why are My Blue Hydrangeas Turning Green

Fact Checked By | Post Updated On:

Hydrangeas are a popular flowering shrub known for their large, showy blooms. The most common variety is the mophead hydrangea, which has round blue or purple flowers. But sometimes, these blue hydrangeas can turn green.

There are a few reasons why this might happen.

When it comes to flowers, there are few that can match the beauty of blue hydrangeas. Unfortunately, these stunning blooms sometimes turn green – and it’s not always clear why. There are a few possible explanations for why your blue hydrangeas might be turning green.

One possibility is that the pH of your soil is too high. If the soil is too alkaline, it can cause the flowers to change color. You can test the pH of your soil with a simple at-home test kit (available at most gardening stores).

Another possibility is that you’re overwatering the plants. Too much water can cause the blooms to fade in color. Make sure you’re only watering when the soil is dry to the touch; otherwise, you might be drowning your plants!

Finally, if you live in an area with high temperatures, that could also be causing your hydrangeas to turn green. The heat causes the flowers to open up too quickly, which bleaches out their color. If this is the case, try moving your plants to a shady spot or providing them with some extra protection from the sun (like a sun umbrella).

Whatever the reason for your green hydrangeas, don’t despair – they’re still beautiful! And with a little troubleshooting, you should be able to get those gorgeous blue blooms back in no time.

How Do You Get Hydrangeas to Stay Blue?

Most hydrangeas will stay blue if they are grown in acidic soil. You can lower the pH of your soil by adding sulfur, aluminum sulfate or iron sulfate. If your soil is already quite acidic, you may not need to add anything.

If you want to be sure your hydrangeas stay blue, you can also buy a pre-mixed fertilizer for acid-loving plants at your local nursery or garden center.

Why Do Blue Hydrangeas Lose Their Color?

Hydrangeas are one of the most popular flowers in the world. They come in a variety of colors, including blue. But why do blue hydrangeas lose their color?

The answer has to do with the chemistry of hydration. Blue hydrangeas contain a pigment called delphinidin, which is what gives them their blue color. When delphinidin comes into contact with water, it turns red.

This is why your blue hydrangeas may turn pink or red if you water them too much. So if you want to keep your blue hydrangeas looking blue, make sure you don’t overwater them!

What Do You Do When a Pink Hydrangea Turns Green?

If your pink hydrangea turns green, don’t worry! This is a common issue and it’s usually easy to fix. First, check the soil pH levels.

Pink hydrangeas need acidic soil to maintain their color, so if the pH levels are too high, the flowers will turn green. You can lower the pH by adding sulfur or aluminum sulfate to the soil. Just be sure to follow the directions on the package carefully so you don’t damage your plant.

If the soil pH isn’t the problem, then it’s likely that your plant isn’t getting enough sunlight. Pink hydrangeas need at least 6 hours of direct sun per day to stay pink. If possible, move your plant to a sunnier spot and see if that does the trick.

If you still can’t get your hydrangea to turn pink, you can always try painting it! Just use pink latex paint or food coloring diluted with water and paint the blooms as desired.

How Do You Keep White Hydrangeas from Turning Green?

There are a few things you can do to keep your white hydrangeas from turning green. First, make sure that they are getting enough sunlight. If they are in too much shade, they will start to turn green.

Second, make sure that they are getting enough water. Hydrangeas need a lot of water, so make sure that you are watering them regularly. Third, apply an acidic fertilizer to the soil around the plants.

This will help to keep the soil pH low, which will prevent the hydrangeas from turning green. Finally, prune the plants regularly to promote new growth.

Should I Cut off Green Hydrangea Blooms

If you’re wondering whether or not to cut off green hydrangea blooms, the answer is yes! Cutting off the blooms will encourage the plant to produce more flowers. Here’s how to do it:

1. Using sharp pruning shears, cut the stem of the bloom just below the flower head. 2. Make sure to cut at an angle so that excess water can drain easily from the stem. 3. Repeat this process for all of the green blooms on your plant.

4. Once you’ve removed all of the blooms, give your plant a good watering and fertilize it according to label directions. With a little extra care, you can enjoy an abundance of beautiful hydrangea blossoms all season long!

Why are My Pink Hydrangeas Turning Brown

If your hydrangeas are turning brown, it is likely due to a lack of water. Hydrangeas need 1-2 inches of water per week, and even more during hot, dry periods. Browning can also be caused by too much sun or wind exposure.

Be sure to provide your hydrangeas with plenty of water and shelter from the elements to prevent browning.

Why are My Endless Summer Hydrangea Blooms Green

Endless Summer hydrangeas are a type of hydrangea that bloom continuously throughout the summer. They are known for their large, showy flowers and their ability to tolerate hot, humid weather. However, sometimes their blooms may turn green instead of the usual blue or pink.

There are several reasons why this may happen: 1. The plant is not getting enough sunlight – Endless Summer hydrangeas need at least 6 hours of direct sunlight per day in order to produce vibrant blooms. If your plant is in too much shade, the blooms will likely be pale and greenish in color.

2. The soil pH is too high – Hydrangeas prefer slightly acidic soil with a pH between 5.5 and 6.5. If the soil pH is higher than that, it can cause the blooms to turn green. 3. You’re using too much fertilizer – It’s important not to over-fertilize your Endless Summer hydrangea as this can also lead to green blooms.

Stick to a light fertilizer application every few weeks during the growing season and avoid using any fertilizer at all during the winter months when the plant is dormant. 4. There’s something wrong with the water supply – If you’re using tap water to water your plants, it could contain high levels of chlorine or other minerals which can cause the blooms to turn greenish in color.


If your blue hydrangeas are turning green, it’s most likely due to too much iron in the soil. Iron is essential for plant growth, but too much of it can cause leaves to turn yellow or brown. If you think your soil might be too high in iron, you can try adding aluminum sulfate to the soil around your hydrangeas.

This will lower the pH of the soil and make it more acidic, which will help prevent the leaves from turning green.
