What Makes Hydrangeas Different Colors – To get hydrangea flowers purple, start by getting the soil pH to a slightly acidic level between about 5.0 and 6.0. Make sure the plant gets adequate amounts of important minerals like aluminum as well as direct morning sunlight and plenty of water.
Making hydrangeas purple is not as difficult as it may seem. With the right soil pH, fertilizer, and type of care, you can easily transform your hydrangea flowers from pink to a beautiful shade of purple.
What Makes Hydrangeas Different Colors
Soil pH plays an important role in determining flower color for bigleaf and mountain hydrangeas. The ideal soil pH range for these flowers to turn a deep shade of purple is between 5.0-6.0 on the acidity scale (7.0 is neutral). If your soil’s acidity is outside this range, you can use sulfur or aluminum sulphate (or garden lime to bring it up) to lower it before planting your bushes or applying any fertilizer treatments. Are.
How To Change Hydrangea Flower Color
Once you’ve established the right soil pH level to produce deep shades of purple flowers, adding some fertilizer can help promote even more vibrant colors in your flowers. Look for products specifically formulated for flowering plants. But keep in mind that excessive use of fertilizer can cause more harm than good. For example, adding too much phosphorus when growing hydrangeas can make it difficult for them to absorb the aluminum needed to bring out the blue color.
, This shrub produces large clusters of flowers that can range from pink to blue depending on the pH level of the soil. In acidic soil with a pH less than 6, the flowers will be pink; If the soil is more alkaline with a higher pH level, they will be blue. However, it is possible to achieve certain shades of purple by adjusting both the acidity and alkalinity levels in your soil.
, These plants produce flattened clusters of small flowers that are surrounded by larger flowers around their edges. The color range of these plants includes blue, pink and purple as well as white or cream colored flowers, depending on the variety you choose. The most popular mountain hydrangea is called ‘Tough Stuff’.
The color of your hydrangea flowers can be affected by the pH of the soil. Soil pH measures how acidic or alkaline (basic) your soil is. The scale runs from 0 to 14 with 7 being neutral. Lower numbers indicate greater acidity while higher numbers indicate greater alkalinity. Different plants prefer different levels of soil pH for optimal growth and flower production. Generally, a range of around 5.0 to 6.0 in terms of pH level can encourage purple flowers.
Hydrangea Color Change
The color of hydrangea flowers depends on the amount of aluminum available in the soil. The amount of aluminum available depends not only on whether aluminum ions are present in the soil matrix but also on whether the chemical conditions of the soil are such that the aluminum is available to be absorbed by the plant.
In acidic soils (with low pH), aluminum ions are released into the ground, making them easier to absorb by plant roots. This causes hydrangeas to produce blue flowers instead of pink flowers. That said, it can be difficult to obtain a blue-violet color even in acidic soils if there is too much phosphorus available, as it reacts with and prevents the absorption of aluminum to some extent.
On the other hand, if your soil is alkaline (high pH), there will be less aluminum available for absorption, so your hydrangeas will likely take on a pinkish-violet color. Even if there is enough aluminum in the soil, the plant will have trouble absorbing it at high pH.
Fertilizing your hydrangeas is an important part of keeping them healthy and vibrant. Proper fertilization can help promote the growth of purple flowers, making it a great way to add color to your garden.
Types Of Hydrangeas
The best time to fertilize hydrangeas is early spring before new growth begins. This will give the plants enough time to absorb the fertilizer nutrients before flowering. It’s also important to remember that you should only add fertilizer when the soil is moist; If it is too dry, the plant will not be able to absorb the fertilizer properly.
Depending on what type of fertilizer you use, you may need to apply it more than once during the growing season. If a slow-release fertilizer is being used, one application per year should be sufficient for most types of hydrangea bushes. However, if using granular fertilizer, two applications may be necessary – once in early spring and again in mid-summer when flowers begin to form but before the buds have fully bloomed.
Hydrangeas require regular watering in dry climates. Too little water can cause withered leaves and discolored flowers, while too much water can cause roots to rot. Aim to drink about 1 inch of water per week, either from rainfall or irrigation. If you’re unsure how much your plants are getting each week, use a rain gauge or soil moisture meter as a guide.
To promote healthy growth and vibrant purple flowers, hydrangeas should be fertilized once each month during their growing season with an all-purpose fertilizer that contains some phosphorus (the middle number on the label). Avoid over-fertilizing as this can cause weak stems, mineral imbalance and poor flowering.

If your hydrangeas are blue but you want them to be purple, consider adding some garden lime to make the soil less acidic. If your hydrangeas are pink but you want them to be purple, consider adding some aluminum sulfate to make the soil a little more acidic.
Pruning helps keep hydrangeas neat and tidy, as well as promotes better air circulation around the plant which reduces the risk of disease. Prune after flowering by removing any dead wood or pruning branches outward from the center of the bush to a bud. This will help encourage more flower buds to bloom the following year.
Mulch helps retain moisture in the soil, which is important for keeping hydrangea roots cool during the hot summer months when temperatures rise above 90 degrees Fahrenheit (32 Celsius). Use an organic mulch such as shredded bark or compost at least 3 inches thick around your plants, but avoid piling it on top of their stems as this can cause them to rot due to lack of air circulation.
Bigleaf hydrangeas prefer partial shade so they don’t get scorched by direct sunlight throughout the day during the peak hours of summer, especially if you live in a hot climate where temperatures can exceed 100 degrees Fahrenheit (38 Celsius). Aim for 4-6 hours of indirect light each day; If possible, try to plant near trees that provide a little shade without completely blocking sun exposure for most parts of the day.
Why Are Hydrangeas Different Colors?
No, coffee grounds will not turn hydrangeas purple. Coffee grounds are not highly acidic. They can be beneficial to some plants, especially after fertilizing, but they do not have the ability to change the color of hydrangeas.
To dye hydrangeas purple, you need to use a solution of flower food. Start by mixing 1 teaspoon white vinegar and 2 tablespoons sugar in 1 quart warm water. Then, add a few drops of blue or purple food coloring to the mixture. Finally, pour the solution into the vase containing your freshly cut hydrangeas and let them sit for at least 24 hours before displaying them. The longer they remain in the solution, the brighter their color will become. This is always a surprise for gardeners. You buy a plant with blue flowers and later discover that the flowers are now pink. Why does this happen and what can you do about it?
Hydrangeas are a very popular garden plant. They are a perennial shrub that comes in a variety of colors, from white, to pink and lavender, to the highly prized blue flowers.
The mop head or lacecap varieties, as well as some paniculata varieties, are some that change color depending on the composition of your soil.

The color of hydrangea flowers is affected by the acidity or alkalinity of the soil in which they are growing.
How To Change Hydrangea Flowers From Pink To Blue (or Vice Versa)
The easy answer to your question why hydrangea turns blue is: high acidity = blue flowers, while low acidity (or more alkaline soil) = pink flowers.
This is one reason why hydrangeas planted under pine trees often have blue flowers, as pine needles are acidic.
Generally, acidic soil has a pH of less than 5.5 – 6. If you use a planting mix formulated for acid-loving plants, so the soil pH is low to begin with, you will get blue or lavender-blue flowers. Colour.
Alkaline soils with a pH above 7.0 produce pink and red flowers. The pH range is between
