Large-leaved hydrangeas are stunning flowers with a wide range of hues, including vivid blues, purples, pinks, and white. Despite having their origins in Japan, these blooms thrive in most regions of the world. By altering the pH levels of the soil around the hydrangeas, you can change their color. Hydrangeas may be dyed any color, and all it takes is a little work to make your white hydrangeas appear their finest.
Check the pH of the hydrangea’s surrounding soil. The more acidic it is, the higher the level. Maintain a pH between 6.0 and 6.2.
- Large-leaved hydrangeas are stunning flowers with a wide range of hues, including vivid blues, purples, pinks, and white.
- Check the pH of the hydrangea’s surrounding soil.
Add a slow-releasing, evenly-balanced fertilizer with nitrogen, phosphorus, and potassium. Pick up some quality fertilizer from the supermarket, like 10-10-10.
Make sure the pH level is not too high by testing it once more. No more than 7.0 should be the pH level.
Once in late winter, fertilize the area around the hydrangea. Each 100 square feet of soil should receive 1 kg of fertilizer.

Use a garden hose to water your plants on a regular basis, but watch out not to overwater them or let the water stand on the soil. The plant could wilt and decay if it receives too much water. To safeguard the plant, surround the base with 3 to 5 inches of mulch. Mulch around hydrangeas with compost or finely chopped wood bark.
White hydrangeas often contain no pigment and do not change color. White hydrangeas, however, have the potential to develop blue or pink tips as they age. By applying a balanced fertilizer that is low in phosphorus and maintains the acidity levels low, you can try to prevent it. If the pH levels in the soil need to be adjusted, you might need to fertilize in the spring or summer. Avoid trying to change the pH level too drastically at once because this could kill the plant by drying it out.
Make sure the hydrangea is in a location with cool afternoon shade and morning sun. Flowers may wilt and become brown if the weather is too hot and dry.
If you want to provide shade for a hydrangea, don’t put it under a tree because the tree will probably take the nutrients and hurt the hydrangea.
My white hydrangeas are pink—why?
Blue hydrangeas were detested by my mother-in-law and disparaged as garish trailer park plants. In an attempt to kill the roots, she poured hot grease from her kitchen upon them, but it was ineffective. The blue blooms, which clashed with her magnificent golden euonymus and crimson artificial poinsettias, just kept coming.
Hydrangea Colors Changing She could have changed the color of her hydrangeas to a pink hue that looks much better with red fake poinsettias if she had known the method I’m about to share. She only needed to alter her soil; she didn’t need to change her mindset.
You see, the pH of the soil is indicated by the flower color of the majority of French hydrangeas (Hydrangea macrophylla). Flowers turn blue in soil that is extremely acidic (pH < 6). Flowers turn pink or even scarlet in alkaline soil (pH above 7). Purple or a combination of blue and pink blooms on a single shrub are possible on soil that is neutral or slightly acidic (pH 6 to 7). Remember that choices' sensitivity to pH varies. For instance, "Ami Pasquier" and "Purple Tiers" both maintain their color in all but the most acidic soil.
Do white hydrangeas count? I’m sorry, but they won’t cooperate. Regardless of the pH of the soil, they remain white.

Beautiful double-flowered lacecap variety called “Purple Tiers.” In acidic soil, water lily-shaped blossoms are a rich purple color; in alkaline soil, they are pink.
Making cut-flower hydrangeas It makes sense to want to cut the last French hydrangea blossoms because they are so lovely in the yard and may be displayed on your porch or brought inside. However, when the blossoms wilt an hour after being placed in water, it can drive you crazy. How can this be stopped?
Will a white hydrangea maintain its color?
So, when you purchased blue hydrangeas, what happened? Or did you pick a variety with the most gorgeous magenta petals just to see it change by the next season? While the pH of the soil affects the color of blue and pink hydrangeas, white hydrangeas will remain white regardless of the soil’s composition. Which is good news for those hoping to maintain the beauty of their ivory-toned blossoms. Consequently, their hue will naturally change as the seasons pass; yet, you’ll be better off enjoying this change than fighting it.
Many white hydrangeas have vivid yellow-green buds at the start of their flowering periods, which turn crisp white as the season changes, according to McConnell. Some kinds will dry out to an aged white or warm tan as fall approaches. For a little aesthetic interest in the winter, he advises leaving these blooms on the plant, or incorporating them into dried arrangements or autumn wreaths.
Prepare the Flowers
Although it may seem contradictory to use water to dry flowers, hydrangeas benefit from a gentle desiccation process that keeps their color and shape (even the stems end up sturdier when dried this way).
Using a pair of pruning shears, cut each blossom on the angled side, leaving a stem length of between 12 and 18 inches. Take off every leaf from the stalk.
Place the Cut Flowers in Water
After that, arrange your freshly cut flowers in a vase, fill it about halfway with water, and set it aside in a cool location away from the sun. Keep in mind that hydrangea dry best when given room to “breathe,” so take care not to overcrowd your vase with stems.
Allow the vase’s water to totally dry out. After this procedure, which typically lasts two to three weeks, your hydrangeas should feel dry to the touch and the stems should simply snap off. They are now prepared for use.
Use Your Dried Hydrangeas
Your dried hydrangeas can be displayed in a variety of artistic ways. Although they look lovely on their own in a vase, you can also incorporate them into seasonal wreaths or use them in window boxes with other dried flowers. Getting hitched in the autumn? Even your bridal floral arrangements can incorporate them.
How can Annabelle hydrangeas be kept white?
A lot of people are drawn to hydrangeas because of their vivid and exquisite colors. Several of them even alter their color! It’s no surprise that they’re so well-liked with their enormous blossoms and large, glossy green leaves. Don’t let that deceive you, though; adding a stylish white Hydrangea plant to your yard is just as attractive.
Focus on maintaining the health of your white hydrangeas by giving them the right amount of water, light, and fertilizer. If your white Hydrangea is becoming blue or pink, you definitely don’t have a true white variety because white Hydrangeas don’t change color with soil pH like blue and pink blooms do.
Which hydrangea remains white?
- Psilocybe paniculata In home gardens, white panicle hydrangeas are extremely prevalent. These adaptable plants, known for their distinctive conical flower shape, may flourish in a variety of growth environments. Paniculata varieties frequently show to be able to endure greater sun as well as a variety of soil conditions when it comes to cultivating white hydrangeas. There are many white hydrangeas, but many of them also exhibit pink or green tones. The cultivars “Bobo,” “Limelight,” “Little Lime,” “Great Star,” “Quickfire,” and “Sundae Fraise” all yield white hydrangea blossoms.
- Quercifolia hydrangea
- These plants, often known as oakleaf hydrangeas, are renowned for their protracted pyramid-shaped flower spikes. They are the perfect hydrangea for gardeners in more difficult growing zones because they can endure greater temperatures and drier soil conditions. White varieties of oakleaf hydrangeas include “Gatsby Gal,” “Gatsby Moon,” “Snow King,” and “Alice.”
- Hydrophylla hydrangea
- Hydrangeas known as macrophyllas or mopheads feature extraordinarily big flowers that frequently bloom in a variety of vivid hues. However, there are these kind of pure white hydrangea shrubs. Cultivars like “Fireworks,” “Lanarth White,” and “Blushing Bride” may be the most productive for those growing white hydrangea bushes.
- arborescent hydrangea
- Some of the most well-liked white smooth hydrangeas include “Annabelle,” “Incrediball,” and “Invincibelle Wee White.” These white hydrangeas are known to flourish in shady garden sites and, in the right circ*mstances, may even naturalize.
How can blushing bride hydrangeas remain white?
Place these shrubs in a safe location that receives between two and four hours of direct sunlight each day and has some shade. You should have moist yet well-drained soil that is nutrient-rich. Plants will get root rot if they are planted in a permanently wet environment. But for hydrangeas to thrive, there must be plenty of moisture in the soil.
What white hydrangea is the most gorgeous?
White hydrangeas come in a variety of varieties, each of which need particular care and planting conditions to thrive. The four most typical types are as follows:
Smooth (H. arborescens): The most often used cultivar is “Annabelle.” While southern gardeners should grow smooth hydrangeas in moderate shade, full light is where they flower at their best.
Bigleaf (H. macrophylla): Everyone loves bigleaf hydrangeas, but not everyone can grow them. They are the traditional florist varieties of hydrangea. Bigleaf plants thrive in moist, well-drained soils and partial shade. The majority can survive in Zones 5 or 4, depending on winter protection.
Cone-shaped flowers are produced by panicle hydrangeas (H. paniculata), which are hardy and simple to grow. They thrive in all but the coldest climes and appreciate full sun (Zone 3). Panicles normally bloom in the middle of summer, later than other types. Depending on the variety, heights can range from three to ten feet.
The oakleaf plant (H. quercifolia) has oak-shaped leaves that change into striking hues of burgundy, rust, or orange in the fall. As the weather cools, the white flower heads typically turn pink or tan. This native species’ cultivars, which are typically hardy to Zone 5, thrive on dry soils and full sun to moderate shade.
Are white hydrangeas shade-loving?
In contrast, hydrangeas are a plant. Most thrive better in mild shade than in full sun, and they flower for months as opposed to just a few short weeks.
Hydrangeas enjoy water, as their name suggests. They thrive in clay and damp soils, but some of them seem to be able to adapt to considerably drier environments, especially if they are not exposed to intense sunlight. They are therefore most suited for growing in the mild shade of deciduous trees, where the soil is likely to be rich in organic matter from leaf fall.
The most practical Hydrangea paniculata cultivars bloom from mid-summer through to October, depending on the variety. Conical flower heads come in a variety of shapes and sizes, from robust panicles of sizable sterile florets to lacy mingles of tiny beaded fertile flowers. Throughout the winter, both can still be beautiful as they transform into parchment. Late winter pruning encourages robust, upright shoots; each year, trim down to a solid structure.
When planted with dark evergreens like Viburnum davidii and Aucuba japonica ‘Rozannie,’ Hydrangea paniculata is especially beneficial. Use a variegated Euonymus fortunei ‘Emerald Gaiety’ as an underplant. Perfect for adding color to a dark bed or border.
One of the most well-known hydrangeas is Hydrangea arborescens ‘Annabelle’. In the latter half of summer, it’s impossible to ignore the enormous, sponge-like white flowerheads and soft green foliage. It looks great with silvery miscanthus and dark sarcococcas beneath white-barked birches. Plant it where it can rely on the support of neighboring plants because the weight of the flowerheads can cause the stems to sag and flop. Although there are differing views on how severe to prune, there is little question that it needs to be trimmed down in the late winter to a few centimeters from the ground level. Excellent on chalk and wonderful for filling a shadowy corner.
The architectural foliage of the oak-leaved hydrangea, Hydrangea quercifolia, is nearly as prized as its floral blooms. It is never among the most well-liked because of its habit, which may be somewhat awkward. The foliage in the fall develops deep colours in areas where it receives a sufficient amount of sunlight. The foliage are a rich green color in the shade. Similar to Hydrangea paniculata flower heads, although frequently more pendant. One of the most impressive varieties is Hydrangea quercifolia “Snowflake,” which has enormous sprays of double, creamy-white flowers.
The less common Hydrangea macrophylla has coarser stems and smaller leaves than the Hydrangea serrata.
The former has huge leaves and blooms, but the latter has little, delicate lacecap flower heads that appear to be more drought resistant than the bigger growing variants.
One well-known variety of free-flowering hydrangea serrata is called “Bluebird.” The delicate blooms are gentian blue in acidic soil and mauve-pink in alkaline soil. From late summer on, the leaf is flushed with plum purple, even in the shade.
Numerous Hydrangea macrophylla cultivars with pink and red flowers will “blue” in acidic soil. If your soil has a higher pH, you can cultivate blue blossoms by planting them in a pot of ericaceous compost and regularly spraying them with hydrangea colorant. Although the purple-pink blossoms are equally lovely, for some reason blue hydrangeas are always more sought-after.
There are two different blossom shapes in hydrangea macrophylla variants. Some plants are referred to as mopheads; these are the ones with enormous, sterile florets in their bold, massive heads. The lace-cap hydrangeas are the other species. These feature heads with tiny, fertile florets that are encircled by bigger, sterile florets. Pollinators are drawn to the lacecaps more. The gorgeous lacecap hydrangea Hydrangea macrophylla ‘Zorro’ has black stems and blooms that become vibrant blue in acidic soil, even in partial shade.
Varieties of Hydrangea macrophylla with white flowers never change color in response to soil type.
However, they may turn pink or even deep blue when exposed to the light or when the weather is bad. One of the best white mophead hydrangeas is Hydrangea macrophylla ‘Madame Emile Moulliere, which when grown in the sun has reddish tinges along the edges of the florets; in contrast, when planted in the shade, the flowers are completely white.
Secrets of success
Even while some of these hydrangea cultivars can withstand drought better over time, newly planted plants still require frequent watering to thrive.
Despite being very resilient, hydrangeas are susceptible to frost damage as the spring season begins. Avoid placing them in areas where this might be a problem. In general, Hydrangea paniculata is more resilient to spring frosts.
Every year, fertilize hydrangeas using a slow-release fertilizer meant for flowering plants. Potash-rich fertilizers aid in hardening the growth and promoting blossom production.
