To keep hydrangeas pink naturally, you’ll need to adjust the pH of the soil that the plants are planted in. Aim for a slightly acidic soil pH between 5. 0 and 6. 0 for the best results. To test your soil pH and adjust it accordingly, you can purchase a soil testing kit from any local garden center.
A good rule of thumb is to add 1/3 part of elemental sulfur for every one gallon of soil in the area where the plant is planted. This can be done by purchasing a pre-mixed soil amendment from a garden center, or by purchasing elemental sulfur separately.
If the soil pH is already slightly acidic (between 5. 0 & 6. 0), then you may have enough sulfur present and you won’t need to make any changes. You can also add a controlled-release fertilizer to the plant at the beginning of each growing season to ensure its health.
Once the soil pH is at the desired level and the proper nutrients are provided, your hydrangeas should be able to maintain a pink hue naturally.

What can I add to my hydrangeas to make them pink?
If you want to make your hydrangeas pink, one solution is to add an aluminum sulfate solution to the soil around the base of the plants. Aluminum sulfate can be purchased at most garden centers and is usually mixed with water at a rate of 1 teaspoon of aluminum sulfate per gallon of water.
The aluminum sulfate not only lowers the pH of soil, which makes it more acid, but it also increases the amount of aluminum ions available for uptake by the hydrangeas. Hydrangeas take up the aluminum ions and replace some of the hydrogen in the petals with the aluminum ions, resulting in a pink flower.
Additionally, adding fertilizer that is high in phosphorus and nitrogen, such as bone meal or blood meal, can also help encourage the blooms to come in a more vibrant shade of pink.
Will Epsom salts make hydrangeas pink?
Yes, Epsom salts can make hydrangeas pink. The magnesium sulfate found in the salts helps to reduce the acid level in the soil and increases the soil’s alkalinity. This, in turn, produces a more alkaline environment that encourages the hydrangeas to bloom in pink tones.
For success, sprinkle one tablespoon of the salts near the base of the flowers every two weeks during the growing season. Make sure the salts make direct contact with the soil and that there are no obstacles in front of them, as this will prevent them from absorbing correctly into the soil.
Will vinegar turn hydrangeas pink?
No, vinegar will not turn your hydrangeas pink. Vinegar has an acidity level that is considered too low to affect the color of your flowers. It is a common misconception that vinegar can alter the color of flowers, but this is inaccurate.
In order for your hydrangeas to turn pink, you must make adjustments to the pH level of the soil to achieve an alkaline environment. To do this, you can incorporate garden lime or use a solution of 1 cup of alum dissolved in 1 gallon of water.
Alum can make the flowers turn from blue to pink by lowering the soil pH to around 5. 5. The addition of aluminum sulfate in the soil will also result in pink hydrangeas.
Will baking soda change the color of hydrangeas?
No, baking soda will not change the color of hydrangeas. Hydrangeas produce their beautiful blooms in a variety of shades naturally and the color is determined by the soil, not baking soda. Adding baking soda to the soil around hydrangeas won’t change the color, although it can help balance the pH level and make the plants more tolerant to acidic soils.
Although baking soda has no direct effect on color, too much of it can cause hydrangeas to become chlorine-laden and look severely withered. You should also be careful not to over-fertilize hydrangeas, as this can cause them to produce flowers that lack the satisfactory color they would normally produce.
For those looking to change the color of their hydrangeas, doing so is possible by altering the pH level of the soil around the plants. A slightly higher pH can encourage blue flowers, whereas a slightly lower pH can promote pink or red-colored blooms.
What color does Epsom salt turn hydrangeas?
Epsom salt can be used to change the color of hydrangeas, but the type of color produced depends on what type of soil your hydrangeas are planted in. If your hydrangeas are planted in alkaline soil, adding Epsom salt can turn hydrangeas to a shade of pink; however, if planted in acidic soil, the color of your hydrangeas should turn to a deep blue.
Gently work the salt into the soil around your hydrangeas, making sure to not go overboard as this could cause damage to your plants. Epsom salt should also be reapplied every year throughout the growing season to maintain the coloring.
If you wish to adjust the shade of color, simply change the amount of Epsom salt you add to the soil. It may take up to a few months for the color change to be seen, so be patient.
How do you make pink hydrangeas with baking soda?
Making pink hydrangeas with baking soda is fairly simple. To begin, you will need a container or vase full of fresh hydrangeas, baking soda, and some water. First, dissolve the baking soda in a few cups of warm water.
Fill the vase or container with that baking soda solution, making sure that all the stems of the hydrangeas are submerged. Then, leave the flowers in the mixture for at least 8 hours. After 8 hours, remove the flowers and replace the solution with fresh water.
Over the next 24-48 hours, the blooms should start to change colors, until their turn a shade of pink. To keep the color vibrant, change the water and replenish the baking soda solution as necessary.
Why are my hydrangeas not turning pink?
It is possible that your hydrangeas are not turning pink for a variety of reasons, but the most likely reason is that the soil your plants are in is not acidic enough. Hydrangeas require slightly acidic soil, typically with a pH of 5.
0 to 6. 5, in order to turn pink. If the soil is too alkaline, then your hydrangeas won’t be able to take up the aluminum ions necessary to produce the pink coloration and your blooms will likely stay blue.
To address this issue and encourage your hydrangeas to turn pink, you can add aluminum sulfate to the soil in the spring at a rate of one tablespoon per nine square feet of flower bed. Additionally, adding a generous layer of mulch around the base of your plants can help to maintain the appropriate soil acidity.
It is important to regularly check the soil pH throughout the year, as weather changes can affect soil acidity.
How do you apply Epsom salt to hydrangeas?
To apply Epsom salt to hydrangeas, start by purchasing Epsom salt from your local garden or home improvement store. Then, make sure your hydrangeas are consistently watered—they should not be wilting or overly dry.
For established plants, you can dilute 1 tablespoon of Epsom salt in 1 gallon of water, or for young plants or seedlings, you can use a much weaker solution with only 1 teaspoon of Epsom salt in 1 gallon of water.
Begin applying the Epsom salt solution to your hydrangeas about once a month during the growing season, making sure to keep the solution away from the leaves and in the soil around the base of the plant.
With regular use of Epsom salt, you will help promote blooming, more vibrant colors, and increased hardness and vigor in your hydrangeas.
Can I use white vinegar on hydrangeas?
Yes, you can use white vinegar on hydrangeas! Applying white vinegar to your hydrangeas is an effective and safe way to adjust the pH level of your soil to support the health of the plant. White vinegar is acidic, so adding it to the soil helps to create conditions more favorable for your blooms.
To use, mix one part white vinegar to five parts water and pour it around the base of the hydrangea. This should be done every three months, but be sure to avoid getting any of the vinegar solution on the leaves.
It may also help to check the soil’s pH levels before applying the vinegar solution, as too much acidic soil could hurt your hydrangea’s health.
What fertilizer makes hydrangeas pink?
The type of fertilizer needed depends on the soil in which the hydrangeas are planted. Generally, gardeners should use a fertilizer that has a slightly high nitrogen and a slightly acidifying fertilizer that has aluminum sulfate or ammonium sulfate.
Additionally, a fertilizer that is high in phosphorous, such as a bloom booster fertilizer, epsom salts, or Miracid, can help make hydrangeas pink. If the soil’s PH is on the more alkaline side, limestone or lime can be used to acidify the soil, helping turn the flowers pink.
Using other natural amendment such as acidifying compost and fertilizer with iron sulfate can also help turn hydrangeas pink. The most important thing to do when fertilizing hydrangeas is to follow the manufacturer’s instructions for timing, amount, and rate of application.
Can I just sprinkle Epsom salt on plants?
Yes, you can sprinkle Epsom salt on plants. Epsom salt is rich in magnesium sulfate, which is an essential mineral for plant growth. When sprinkled on the soil, it helps plants absorb important nutrients such as nitrogen and phosphorus.
It also helps to improve root growth and can give plants an extra boost of energy. It’s important to note, however, that Epsom salt should only be used in moderation. Over-application could burn plants, resulting in yellowing of leaves and stunted growth.
Additionally, the salts can affect the pH of the soil, which may not be beneficial for all plants. The best course of action is to consult a soil professional for advice on how much Epsom salt to use on a specific type of plant.
What plants don’t like Epsom salt?
Generally speaking, most plants do not need Epsom salt added to their soil, and some plants may even be sensitive to it. For those plants that do benefit from the use of Epsom salt, too much can cause harm, so the key is to be sure not to overuse it.
That being said, there are a few plants that should not be exposed to Epsom salt. These include some varieties of azaleas, rhododendrons, and ferns. These plants may develop leaves that are yellow, brown, or spotted if exposed to too much Epsom salt.
Similarly, some vegetables, especially tomato and pepper plants, may develop small discolored spots on the leaves when Epsom salt is overused.
In addition, some succulent plants such as cacti and aloes can be particularly sensitive and may suffer dehydration due to the high levels of salt in the soil. For these plants, too much Epsom salt can cause their cells to become filled with water and burst, leading to leaves that appear to have popped open.
It is important to be aware of the plants that can be sensitive to the use of Epsom salt when using it to fertilize and amend the soil. By understanding which plants can be affected by too much salt, gardeners can make sure to properly monitor their use and take steps to protect the plants from potential damage.
