Hydrangeas tend to go through a slight colour change when transplanted due to adjusting to their new soil when you first bring them home. Hydrangea varieties such as hydrangea macrophylla and serrata can range in colour from pink to blue, with every shade of fuchsia, plum, and violet in between. Blue isn’t a prevalent colour for flowering plants , which makes it pretty desirable to gardeners who want their outdoor area to stand out.
What you may not know is that you could have gorgeous blue hues already hiding in your garden , just waiting to show their true colours. In the right conditions, some species of hydrangeas can display that beloved, sought-after shade. If you have a hydrangea already in your garden and are just dreaming of a sea of blue, you can try changing the colour using a home remedy one gardener has found works for them.
Taking to the Hydrangeas in the UK Facebook page, Sarah Hick shared how she was able to turn her shop-bought pink hydrangeas blue without the need to purchase anything. She wrote: “Absolutely love my blue hydrangea. This year I was told a trick to put coppers [coins] in the soil, last year it turned pink now it’s even more vibrant blue!” Referring to the pictures of the vivid blue hydrangea, Sarah said: “This is a French hydrangea I believe.
Absolutely stunning. “I also have a pink one I recently purchased and it gives the garden a really lovely colour.” However, many gardeners argue that it’s aluminium sulphate that’s needed to change the colour of hydrangeas blue which can be found at almost any garden centre.
Organic materials, such as coffee grounds, egg shells or citrus fruit peels are another, more natural method of making soils more acidic. Simply grind either of the previously mentioned ingredients up and work them into the ground. These changes will happen gradually, so it might take an entire year of doing this consistently for it to reach the right acidity.
