Tips for Creating a Hydrangea Arrangement Pin
It is because of their stunning blossoms that hydrangeas have become so popular. White, pink, and blue are all possible hues for them, and they can really change color.
According on the pH level of the soil, the color of lacecap and mophead hydrangeas may shift from pink to blue or from blue to pink. If you want your hydrangeas to be pink, you may change the soil conditions in which they grow.
What Causes the Color Change in Hydrangeas?
Hydrangeas will change color depending on the quantity of aluminum present in the soil and the pH level of the soil in which they are grown. This does not occur with white hydrangeas, but it does occur with blue and pink variations of the flower.
When the soil is more acidic, there is an abundance of aluminum available for the plant to use. It is absorbed by the hydrangeas via their roots.
The plants, on the other hand, do not have access to aluminum when the soil is alkaline. Your blue hydrangea may blossom blue one year and pink the next year because your soil is excessively alkaline, and you will have to replace it.
A blue flower will appear on the plant if the soil is acidic. By adjusting the pH levels of your soil, you may modify the color of bigleaf hydrangeas that are pink or blue in hue.
To begin, get a soil analysis.
It is necessary to do a soil test in order to fully understand the health of your hydrangeas. For the most precise results of your pH levels, it is recommended to have a professional test performed.
You may also purchase a pH meter, which will allow you to determine the pH of the soil. Knowing how alkaline or acidic your soil is can allow you to make adjustments to it in order to control the color of your hydrangeas’ flowers.
If you want a professional test done, you may contact your county extension office or one of the local colleges.
How to Conduct a Soil Analysis at Home
Obtain a sample of your soil to begin the process. In order to properly store the soil, you need dig a hole that is four to six inches deep and fill it with it. The soil should be stored in a glass or plastic container.
A teaspoon of dirt is plenty, but you may add a bit more to make it more textured and cohesive. If you wish to test a number of different regions, you may combine them.
Make careful to utilize gardening tools, and break up any clumps with a trowel if they seem to be forming. You should avoid using your hands since they have the potential to alter the pH level of the soil.
Allow your soil to dry completely before placing a little quantity of it into the vial that comes with the test kit. Make certain that it is merely dirt and not rocks or other items before proceeding.
To transfer the soil into the vial, use a little spoon and avoid touching the dirt with your fingers. The vial will have a line on it that will tell you how much dirt you should put in.
You may next open one of the capsules that came with your package and pour the contents of that capsule directly onto the soil. Using the plastic eyedropper, carefully fill the vial with distilled water until it reaches the top of the vial.
Water that has been distilled has no taste or odor; tap water, on the other hand, may contain contaminants.
You may now shake your vial by placing the lid on top of it. Continue to shake it until the dirt and powder are entirely dissolved in the water in the vial, then drain the vial.
Before you verify the color, you should place the vial on the ground and let the earth to settle for 60 seconds. Then, make a comparison between the color you observe and the chart that is printed on the vial.
It is necessary to determine the pH level of your soil before deciding how to make it work for the color of hydrangeas that you want to grow in it.
How to Turn Your Hydrangea into a Pink Hydrangea
If you want your hydrangea to blossom pink, the first step is to make sure that you have bigleaf hydrangea in either the pink or blue kind growing in your garden. After then, you have a number of alternatives.
You should think about testing your soil to find out what pH level it is at right now. It’s a good rule of thumb to say that if your soil’s pH is between 6.0 and 6.2, your flowers will be pink. If your soil’s pH is between 5.5 and 6.5, your blooms will be purple, and if your soil’s pH is 5.5 or lower, your blooms will be blue.
If you want your hydrangeas to blossom pink, you may amend the soil with lime; if you want blue flowers, you can amend the soil with aluminum sulfate. The quantity of fertilizer you need is determined on the nature of your soil.
Of course, if you grow your hydrangeas in a container, you will be able to manage the pH of the soil much more readily, which is important if you want the plant to bloom in a certain color such as pink or blue.
Myths Regarding Hydrangeas
Because hydrangeas may bloom in a variety of hues, there are several urban legends about these plants circulating. Even though you may have heard that they are tough to grow, the truth is that they aren’t difficult at all if you provide them with the proper care and attention.
Myth #1: Hydrangeas need a lot of water because of the “Hydra” in their name. This is one of the most widely repeated fallacies about hydrangeas, and it is true in certain cases. When you break down the meaning of the name, it is simple to see how someone may have established this story in the beginning.
Hydra is derived from the Greek word hudra, which literally means “water.” Angea is derived from the Greek word angeion, which literally translates as pitcher or vessel in English. Some believe it was called this way because it resembles a water pitcher, while others believe it was named this way because the three red stems that carry the seeds like a water vessel.
In any case, it was given this name because of its look rather than because of a high need for water. In order to thrive throughout the growth season, hydrangeas need roughly one inch of water each week (including rainfall).
It is possible to destroy hydrangeas very rapidly if you believe this urban legend and overwater them.

You may have heard that hydrangeas will bloom more profusely if you apply fertilizer to them. Fertilizer replenishes nutrients that have been depleted from the soil, and if there are no deficiencies, the fertilizer will not aid in the blooming of your hydrangeas.
With this fallacy, the most common issue occurs when individuals over-fertilize, which has the reverse effect of what is intended. Even if you end up with gorgeous deep green foliage, you won’t have any blossoms on your plant.
There are a variety of reasons why your hydrangeas aren’t flowering as well as you’d want them to, but applying fertilizer when the soil doesn’t need it isn’t the answer.
During the winter months, it is simple to trim hydrangeas and remove the wood that is ready to blossom in the spring. If you trim them back, you will really be cutting away the blossoms, and the plant will not produce flowers as a result.
If your hydrangea plant freezes throughout the winter, it is possible that it may not bloom the following spring. A late spring frost may sometimes hinder the emergence of a flower.
Because your hydrangeas need at least three to four hours of light every day to bloom, make sure that you plant them in the appropriate area. You should avoid applying nitrogen-rich fertilizer to your plants since it encourages leaf growth but not flower production.
Myth #3: Fertilizer may be used to alter the color of hydrangeas’ leaves.
This isn’t correct at all. The color of the bloom is influenced by the pH level of the soil…. In this case, it is determined by whether the hydrangeas’ roots absorb metal or not.
Myth #4: The pH of a hydrangea’s bloom affects the color of the flower.
While certain hydrangeas have the ability to alter the color of their bloom, the majority of them are white, with the color of the bloom changing as the flower matures. If you have blue or pink bigleaf hydrangeas, the color of the flowers might vary depending on the quality of the soil.
Only certain hydrangeas bloom, and their blooming is determined by the pH level and the presence of aluminum. No matter what the pH level of your soil is, if your hydrangeas do not have enough aluminum in their soil, they will not produce blue blossoms.
You must first comprehend what occurs in the soil before you can grasp how the pH level affects it. It is impossible for plants to absorb aluminum molecules from soil that has alkaline conditions because the soil keeps the aluminum molecules together so firmly that the roots of the plant are unable to absorb them.
When the roots are unable to absorb metal, the bloom becomes pink. However, as the soil gets more acidic, the aluminum is released, and the roots are able to absorb the metal.
Because of the presence of metal, hydrangeas may become blue, but if there is just a little amount of aluminum present, the flowers may be purple.
Myth #5: If you add aluminum to the soil, it will turn the blooms blue.
While this may be the case in certain cases, it is not always the case. If you have alkaline soil and then add aluminum to it, the earth will compact and make the metal unavailable to the roots of your hydrangeas, causing them to die.
When your soil has the proper pH level (i.e., it is acidic) but is lacking in the amount of aluminum you need, it is time to add aluminum. This method works best when your hydrangeas are grown in pots and you have complete control over the soil conditions.
Myth #6: Burying a nail in the roots of hydrangeas will cause them to become blue.
Some individuals believe that you may hide a variety of materials beneath hydrangeas, including nails, razor blades, hairpins, and coins, among other things. The difficulty is that unless a few of things happen, there is little likelihood of this plan operating well.
First and foremost, the thing would have to be built entirely of metal or primarily of aluminum. Second, it would have to corrode immediately in order for the aluminum to be released into the soil.
At addition, the pH of the soil would have to be in a favorable range for aluminum to be released. Finally, it should be noted that this method does not truly function.
The pH of the soil should be checked before adding aluminum, and the soil should be checked again after adding aluminum.
What Types of Hydrangeas Have Pink Flowers on Them?
When it comes to finding pink-blooming hydrangeas, you have a few alternatives to choose from. Despite the fact that the majority of hydrangeas bloom in white, there are a few that bloom in pink.
Some of them bloom pink when the soil is alkaline, with a pH more than 7.1, while others bloom pink no matter what the soil pH is, according to the manufacturer.
When grown in alkaline soil, hydrangeas that are classified as mophead hydrangeas have blooms that have the appearance of a mophead and bloom in pink. These plants may reach heights of up to six feet, and there are a few lesser varieties that grow to just three or four feet tall.
Hydrangeas also come in a variant known as the lacecap variety, which is a variation on the bigleaf hydrangea in appearance. When grown in alkaline soil, these plants can produce pink blossoms as a side effect.
Despite the fact that panicle hydrangeas and oakleaf hydrangeas both produce white blooms in the form of a cone, the blossoms of both varieties eventually turn pink. The pH level of the soil has no effect on the growth of this species of hydrangea.
There is one more kind of vine, which is a hybrid called the Roseum, which blooms with pink lacecap flowers at the end of the summer. This kind is also unaffected by the soil’s composition.
When Should I Treat the Soil to Make the Hydrangeas Bloom a Different Color?
The optimum time to treat your soil is in the spring or the autumn, depending on your growing season. If you wish to modify the color of your plants, you should give them adequate time to absorb any metal that is released into the soil throughout the process.
Once you’ve made the necessary adjustments to the soil, it might take anywhere from a few weeks to many months for the color of the flower to really change.
For a more dramatic change in the composition of your soil, you may wish to treat your soil every two to four weeks if you want to see results quickly. It is critical to continue treating the soil since the pH of the soil will ultimately revert to its original level.
Concluding Remarks
The beauty of Hydrangeas when they bloom makes them a popular choice for many people to have as a houseplant. One distinguishing characteristic of bigleaf hydrangeas is that they may bloom in a variety of hues depending on the amount of aluminum present in the soil.
If you want your hydrangeas to bloom differently, you should get your soil analyzed to determine the pH level as well as the amount of aluminum present. Then, make the required modifications to allow them to blossom in shades of pink, blue, or purple, depending on your preference.
