Coca-Cola may be the drink of choice for many people, but it is bad news for your plants. In this blog post, we will discuss why Coca-Cola is bad for plants and some alternative fertilizers you can use to give them nutrients instead!

Is Coca-Cola Bad for Plants?

Yes, Coca-Cola is bad for plants. The sugar in the drink is bad for plants because it causes them to become too acidic. Coco-Cola and other sodas contain phosphoric acid, which is bad for plants. The massive amount of sugar in Coca-Cola is also an issue for the plant.

The sugar content of a 12oz serving (355ml) has 39g of sugar in the form of high fructose corn syrup. This sugar is broken down by bacteria into acids such as lactic, acetic, and formic acids when they come into contact with soil microbes. These plant damaging substances will kill off beneficial microorganisms needed within healthy soil, which means fewer nutrients being absorbed through roots causing stunted growth due to lack of nutritional uptake. It also makes plants more susceptible diseases like root rot or fungus because they are unable to have enough nutrients needed to grow healthy roots.

What can you fertilize plants with instead of Coca-Cola?

Instead of fertilizing your plants with Coca-Cola, you can try using used coffee grounds or tea. Reusing your tea and coffee grounds as fertilizer is also a great way to make use of something that would normally be thrown away!

Coffee is a great alternative because it has nitrogen, phosphorus, and potassium which are all needed for plants to grow healthy roots. Plus, coffee contains caffeine that can aid some types of plants’ growth in the long term by stimulating photosynthesis (the process of converting light into energy). It’s also able to make them more resistant against pests like aphids due to its citric acid content acting as an insecticide when sprayed on leaves so they won’t be eaten.

Tea also works really well too since there are high levels of organic acids such have polyphenols with anti-bacterial properties. This makes the soil less susceptible to harmful bacteria but still providing enough nutrients through composting decomposition because it’s not killing off beneficial microorganisms within soils.

You should make sure that the plant you want to fertilize does well in with slightly more acidic soil, as both coffee and tea can lower the pH of the soil.


So the next time you want to fertilize your plants, why not use these alternatives instead of Coca-Cola? It’s better for them and it’ll save money too!
