The sepals are naturally green and as they age the pigments of white, pink, or blue will overpower the green which is what causes your hydrangea blossom to change colours and eventually fade to green with time. Some gardeners argue that your colour is controlled by the amount of aluminium you have in your soil such that high amounts of aluminium give you blue flowers while low amounts give you pink flowers. That only accounts for part of the story. The other part is that your green hydrangea flowers will change colours once they are exposed to longer days of light.
Light gives your plant the power it needs to change colour. In fact, that colour might last for weeks at a time and then suddenly your hydrangea turns to green again as the days start to shorten.
To make flowers purple, reduce the additive amounts by about half. Additive quantities may vary according to hydrangea variety. When lavender hydrangeas start to take on a green tint and the petals begin to dry, they are ready for drying for indoor arrangements.
This may be a good option for gardeners who don't like the look of the green flowerheads on the shrubs. To dry the hydrangeas, cut the flowerheads along with 8 to 10 inches of stalk, remove any leaves and hang upside down in a cool place for a few weeks. The flowerheads can then be arranged and displayed. Some hydrangeas routinely produce green blooms because of their variety.
The blooms usually start out white, then turn green and end in white as they age. 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 Your email address will not be published.
