If water is good for plants, maybe other liquids can be beneficial as well. For example, what does pouring soda pop on plants do? Are there any beneficial effects of soda on plant growth? If so, is there a difference between the effects of diet soda and regular soda pop when used as fertilizer? Read on to learn more about pouring soda on plants.
Soda Pop as Fertilizer
Sugary soda pops are not the most ideal choices for use as fertilizer. Just like salt, sugar prevents plants from absorbing the water -- not what we're looking for.
However, plain carbonated water introduced for a short period of time does encourage plant growth over the use of tap water. Club soda or carbonated water contain the macronutrients carbon, oxygen, hydrogen, phosphorous, potassium sulfur, and sodium that are essential for healthy plant growth. The absorption of these nutrients encourages more rapid growth in the plant.
Therefore, pouring soda on plants, such as Classic Coca Cola, is inadvisable. co*ke has a jaw dropping 3.38 grams of sugar per ounce, which would certainly kill the plant, as it would be unable to absorb water or nutrients.
Other varieties of co*ke such as co*ke Zero, Coca Cola C2 and co*ke Black have little to no sugar, but neither do they seem to have any added benefits over tap water, and they are significantly more costly than tap water.
Sprite has almost as much sugar as Coca Cola and is, therefore, not useful as a soda pop fertilizer. It is, however, useful to lengthen the life of cut plants and flowers. I've heard 7-Up works just as well to increase the life for cut flowers in vases.
Effects of Soda on Plant Growth
Basically, the conclusion is that sugary sodas do not aid in a plant's development, and in fact can retard the absorption of nutrients and water, resulting in death. Diet sodas may be helpful in stimulating plant growth since the lack of sugar will allow the water molecules to easily move to the roots.

However, the effects of diet soda and plants are generally negligible over tap water and far more costly. Club soda does seem to have some benefits due to its high concentration of nutrients favored for plant growth. A
lso, its lack of sugar allows the plant to absorb them into its root system. While water is really the best choice for plants, carbonated club soda will certainly not harm your plants and may even result in larger, healthier, and more vividly green specimens.
FAQs
Soda Pop as Fertilizer
What happens when you pour soda on plants? ›
And although we're clear that plants need sugar to grow, it's not the LaCroix kind of sugar they are looking for. Flavored sodas could easily damage plant roots, breaking their immune systems down and leaving them prone to disease and death.
What soda can help improve the growth of plants? ›
A recent study was done and it was found that during a 10 day period plants watered with club soda grew an average of 157% where plants in the same growing conditions grew only 56% that is 3X more growth!
What does Coca-Cola do for plants? ›
Coca-Cola does not cause for plants to grow taller and grow more leaves. In the end Coca-Cola is very bad for plants and causes for them to dry up faster, die quicker, grow smaller and not to grow as many leaves. My experiment showed that Coca-Cola is not good for plant growth.
Is club soda really good for plants? ›
Club soda or carbonated water contain the macronutrients carbon, oxygen, hydrogen, phosphorous, potassium sulfur, and sodium that are essential for healthy plant growth. The absorption of these nutrients encourages more rapid growth in the plant.
Can I sprinkle baking soda on my plants? ›
When applied to plant leaves and stems, baking soda does slow or stop the growth of fungi. However, the benefits are fleeting at best. Studies have shown that while baking soda impacts the growth of fungal spores, the spores and actively growing fungi are not killed.
Is coffee good for plants? ›
Don't just pour it down the drain — you can use it to fertilize your plants, both indoor and outdoor. Coffee grounds (and brewed coffee) are a source of nitrogen for plants, producing healthy green growth and strong stems. Coffee also contains calcium and magnesium — both of which are beneficial to plant health.
Is beer good for plants? ›
It sounds like it might be a good idea in theory (i.e., a good source of food (carbohydrates) for plants and microorganisms in the soil and minerals to promote better plant growth), but it doesn't work out that way. Beer doesn't help plants and, in fact, it can be detrimental.
Can I put sugar in my plants? ›
Only Use Sugar Water for Cut Flowers
Unlike plant roots, the stems of cut flowers can absorb the sugar, which revives their carbohydrates. Sugar sends the flowers the false signal that the plant is alive and well and should continue blooming. This effect is merely temporary and eventually the flowers die.
Is milk good for plants? ›
Milk, like fertilizer, can aid in your flower's growth by contributing to soil health and its overall vigor, but the beverage is not a replacement for watering with fresh water.
You want to use plain carbonated water only, ideally sparkling mineral water if budget allows. Don't use Tonic water ether. Although it is a form of carbonated water, it also contains quinine and added sugar. Sugar can cause reverse osmosis, making a plant lose water and eventually die.
Is vinegar good for plants? ›
Vinegar as a fertilizer: Nope, doesn't work. Acetic acid only contains carbon hydrogen and oxygen – stuff the plant can get from the air. The other things that may be in vinegar could be good for a plant – but it seems an expensive method of applying an unknown amount of nutrition.
Is cinnamon good for plants? ›
This versatile spice can be used to help root cuttings, to prevent fungus from killing small seedlings, and even for keeping pests away from your home. Once you learn how to use cinnamon powder for plant health, you'll think twice about grabbing harsh chemicals for your gardening needs.
Do soda crystals damage plants? ›
In addition to killing plants, washing soda is also great for cleaning dirt, moss and algae from paving slabs.
Is soda good for indoor plants? ›
Plants can still get these nutrients from the soil when you water them with plain water, but club soda is like supercharged water. The nutrients go straight into the roots and are quickly absorbed. This doesn't mean you should water your plants exclusively with club soda, because that could be too much of a good thing.
Does sugar water help dying plants? ›
Also, soil that is saturated with a sugar solution can attract harmful micro-organisms that can affect the plant's health. There is no scientific evidence that feeding plants sugar water is conducive to plant health. On the contrary, it can harm your plants and even kill them.
