1. Kill Aphids and Mealybugs

To kill aphids and other pests, you will need a bottle of diet coke as the sugar in normal coke would end up attracting ants that promote aphids and mealybug infestation. If you don’t have ant problem then you can use the normal coca-cola too.

Transfer the coke into a spray bottle and use it immediately on the pests before the tingling froth produced by carbon dioxide in the drink goes away. Also, spray a good quantity till you drench them completely to make it work its magic fast.

It can sound surprising but it is beneficial for Gardenias and Azaleas, more specifically. Pouring a small amount like 15-20 ml of Coca-Cola once in a while around the base of these plants can deliver helpful nutrients to the plants, resulting in better flowers!

It can also be a good lawn fertilizer, promoting the growth of grass, thanks to the CO2 content and plants love it! As soda drinks also have traces of potassium, carbon, hydrogen, oxygen, phosphorus, sulfur, and sodium, they contribute to the overall growth of the foliage.

Mix 1 part of coke with three parts of water and use it on the lawn.

3. For Composting

You may find it unusual, but you can use Coke as an ingredient in your compost pile. Coke’s mildly acidic nature will help break down organic matter, while its sweetness helps attract micro-organisms that aid in the composting process.

  1. My outdoor plants were plagued with mealybugs for years and I tried toxic sprays, washing the leaves with soapy water, and squashing them individually and never could get rid of them. But I put a light cola, without any sugar, in a spray bottle and I sprayed my plants till they were wet, and I have no more mealybugs. I have not seen another one since just one treatment. And this cola has not damaged any plant. It is a miracle treatment for me.
