If the flower has turned green then the change in color is not related to the acidity and alkalinity of the soil or the presence of aluminium sulfate which can causes color changes. However it should be noted that a change in soil acidity can cause some hydrangea varieties to change the color of their blooms from blue indicating acidic soil to pink indicating alkaline soil if changes to the soil pH occur.
Hydrangea flowers turn can green in response to less hours of daylight. With fewer hours of sunlight there is less energy for the flower heads to produce the blue, pink or white pigmentation in the blooms. This causes the hydrangea flowers to fade from their original color to green in late Summer. It is thought that it is not necessarily the intensity of the light that turns the flowers green but the shorter day lengths.
This is why at the end of Summer with less hours of light, is when the hydrangea flowers most often turn green whereas at the height or Spring with more hours of daylight the plant has the energy to produce the more colorful pigments in the flowers.
However I must emphasize it is important not to interpret this as advice to place your hydrangea in more intense sun. Hydrangeas are woodland plants that grow naturally under a tree canopy and most varieties do not tolerate full sun as it can scorch the leaves and flowers brown so always plant your hydrangeas in dappled light or morning sun followed by afternoon shade.
It is thought that heat and humidity could also contribute to hydrangea flowers turning green. Hydrangeas turning green appears to be a more prevalent problem in climates that are hot and high in humidity, but the exact reason for this is somewhat mysterious. Hydrangeas are thirsty plants that require the soil to be consistently moist to prevent the leaves and flowers wilting.
If the temperatures are high then the hydrangea can be under stress as the root system cannot draw up moisture quickly enough to replace the moisture loss from the leaves. It is thought that this type of stress combined with the humidity can hasten the hydrangea flowers turning from their original color to a pale green or even brown. Hydrangeas can tolerate some heat and humidity but it is slightly at odds with its natural woodland environment where hydrangea originate, so this may be a reflection of conditions that are different to which they are adapted.
Read my article, how to revive a dying hydrangea. To prevent hydrangea flowers from turning green it is important to replicate the conditions of their native environment with dappled sunlight, watering often to keep the soil moist and to use a well balanced fertilizer in the Spring to ensure the hydrangea has all the nutrients it requires. Even with the best care practices, hydrangeas flowers can still turn green at the end of the season as they age or in reaction to less hours of light resulting in a lower concentration of the color pigments in the flowers.
I've had them for two months and they turned green? Ant advice? Hydrangea blooms do not stay a given color all year round. After a while, the blooms will age and begin a series of color changes that varies from one variety to another. Some pink ones will begin to develop greens then purples or darker shades of pink, etc.
A good trick is to learn which things bloom and when, and then mix them around in your beds as to not have big color voids at any point during the growing season. If your blooms are spent to the point where you no longer enjoy them, cut them off!! Lots of varieties rebloom, and are much more likely to do so if you do that.
I am experiencing green blooms also. I bought a hydrangea with pink blooms. It continued to bloom with pink blooms for a couple years.
I always cut the old spent blooms off. But this year after I cut the old blooms off, it bloomed with green blooms. Wondering why? I miss the more colorful pink blooms. So, in order to try to change it from blooming only green, I am trying this.
Just did it, so no results yet. Anyone had any luck with this? The problem that you describe seems to be premature fading of the blooms. This can be caused by weather issues unusually dry or hot conditions. Or they can go directly from white to brown. During the years that new shrubs have to get established in the garden, they are likely to be more sensitive to moisture and heat issues and this may do this more often than a year old shrub might.
Coffee grounds will have a small amount of nitrogen, little acidity and the egg shells will have some amounts of potassium or calcium. Plus smaller amounts of other minor but good minerals. The "damage" to the blooms has already been done so these ingredients will not be enough to help now..
But, I would leave them grounds and shells there. Just be careful not to add much of them. In the northern states, we are probably heading towards the cold part of the year and you do not want to add lots of nitrogen, since that would keep the plant in "grow" mode just as cold snaps get closer and closer. In the southern areas like mine, low nitrogen or zero nitrogen fertilizers would be fine since the plants tend to go dormant between mid-November and late December.

I'm not sure you will ever see any significant color change using these methods :- First, coffee grounds are not really very acidic - they tend to have a pH that is close to neutral or at the most, only slightly acidic.

You can see green hydrangeas in many floral arrangements and wedding bouquets as they provide a good backdrop for other plants and flowers. Deadheading hydrangeas promotes bigger and more vibrant blooms. If your green hydrangea blooms have wilted, you can go ahead and remove them.
I usually wait for green blooms to fade and only then do I deadhead them. Keeping up a good plant care regimen, looking out for good nutrition and soil acidity are things you can do to minimize the risk of green blooms.
Ultimately, however, you cannot compete with changing light conditions, and despite your best efforts, hydrangeas can still put out green blooms.
Your hydrangea will produce colorful blooms again in a season or two. Until then, you can still propagate your hydrangea plant and enjoy colorful blooms. Your email address will not be published.
