Is Carbonated Water Good For Plants?

You might be surprised to learn that carbonated water can benefit your plants. Gardeners who enjoy experimenting with non-traditional plant care methods may discover that carbonated water can provide the nutrients their plants need in place of more conventional methods of plant nutrition delivery, such as fertilizers and sprays. There are, however, some disadvantages to adding carbonated water that you should know about.

What Benefits Does Carbonated Water Have For Plants?

Though it is commonly believed that plants only absorb CO2 through their leaves, research has shown that this is not the case. Studies show plants can use carbon dioxide (CO2) in carbonated water as a carbon source. Some research has found that compared to control plants watered with plain water, plants watered with carbonated water have higher magnesium, calcium, and zinc levels in their leaves.

Carbonated water accelerated plant growth by more than two times. According to a widely cited study from 2002 by researchers at the University of Colorado Boulder, it resulted in healthier green hues for ten days. Baby Tears were used in the study (Soleirolia soleirolii). Also, some research has found that carbonated water slows growth, while others have found no effect.

Carbonated water can provide mineral benefits to your plants, depending on the type and source. Sparkling water’s increased acidity compared to plain water may boost nutrient availability in the soil and the mineral content of the water itself.

Additional potassium, phosphorus, and sulfur can be found in some carbonated water sources. In addition to the magnesium and calcium naturally present in mineral water, the addition of carbonation makes it ideal for plants. However, carbonated water is not cheap, especially when compared to municipal water or rainwater.

Conditions Suitable For Watering Plants With Carbonated Water

Under specific circumstances, you can speed up plant growth by using carbonated water. You need, for instance, a plant variety that isn’t overly fragile and thrives in carbonated water. If you’re concerned about the side effects of carbonated water, it’s best to limit your usage or alternate between carbonated and regular water.

Only plants that do reasonably well in alkaline soil should be watered with carbonated water. For acid-loving plants, a sharp rise in pH levels can be extremely harmful because it inhibits the ability of their roots to take in water and nutrients. To lessen these effects, try alternating between flat water and carbonated water.

Gardeners who enjoy experimenting with non-traditional plant care methods may discover that carbonated water can provide the nutrients their plants need in place of more conventional methods of plant nutrition delivery, such as fertilizers and sprays. The macronutrients in carbonated water are essential for a plant’s continued growth.

Benefits Of Using Carbonated Water On Plants

Carbon is an essential part of photosynthesis, so it plays a significant role in plant development. Plants can grow larger and more quickly in high-carbon environments and become more resistant to drought. The increased drought resistance is because plants exposed to higher CO2 concentrations don’t need to open their stomata to absorb the gas.

This way, the plant will get by with less water because less will be exposed to evaporation. For a week, plants watered with carbonated water will mature more rapidly than their counterparts watered conventionally.

Carbonated water’s varied nutrient composition is responsible for the rapid development and improved appearance of the plant’s leaves and stalks. Plants irrigated with carbonated water also appear healthier, with greener leaves and stalks.

Why Should You Use Carbonated Water On Plants?

Scientists from the University of Colorado found that carbonated water has macronutrients that plants need to thrive. Minerals such as potassium, oxygen, hydrogen, sulfur, and sodium can be found in carbonated water.  The carbonated water helped the plants grow more than twice as big as those in regular water. Solubilized nutrients are more readily available to the plant and less likely to be lost to runoff.

Carbonated water’s main perk is that it’s packed with micronutrients. Oxygen, potassium, carbon, phosphorus, and sodium are all examples of macronutrients that can be found in carbonated water.

All of these things are crucial for the development of vegetation. When diluted in carbonated water and poured over your plants’ roots, these nutrients are quickly absorbed by the plant and stimulate rapid growth. The macronutrient particles found in carbonated water are the main reason for its usefulness.

Drawbacks Of Carbonated Water

While carbonated water can help your plants reach their maximum height more quickly, one major drawback is that your plant may not remain healthy for as long as it would have if allowed to grow at its own pace using regular fertilizer, water, and nutrient solutions.

In other words, you might have a tall, healthy, green plant sooner, but it won’t last as long if you don’t water it regularly. Another potential problem is that carbonated water can raise soil pH and leach calcium, neither of which is good for the plant.

Instructions For Using Carbonated Water With Plants

Before using carbonated water, dilute it with water at 50 percent. While watering, the carbonated water needs to trickle slowly into the soil to promote healthy plant growth. This way, the plant will have plenty of time to absorb the nutrients and carbon dioxide. As cold water can shock plant roots and stunt plant growth, bring the solution up to room temperature.

Using carbonated water at the plant’s base is best and not on the leaves. Also, note that giving your plant a weekly regimen of carbonated water can have many positive effects on its health. Carbonated water’s supplemental carbon dioxide and nutrient load help plants flourish when it’s growing season.


The macronutrients in carbonated water are essential for a plant’s continued growth. These elements, which the plant’s roots can take in and use, are crucial to the plant’s development and growth. Plants that have been watered with carbonated water have the potential to grow more than twice as quickly and develop greener hues that are more vibrant.
