Baking soda, also known as sodium bicarbonate, is similar to one of the properties of cinnamon due to its ability to inhibit fungal growth in the soil. A small amount of baking soda is fine if you don't use it often, but be careful with the amounts recommended in this video. If used once a month, salts can build up in the plant's soil. Too much sodium can kill your plants.
Do not confuse it with table salt. Epsom salt is magnesium sulfate. Although it has salt in its name, pure Epsom salt does not contain sodium. As in coffee, the magnesium contained in this component is the main beneficial element for plants, while the sulfur (sulfate) is acidic. Many plants prefer slightly acidic soil, but too much of this product can create a pH imbalance that can stunt or kill your plants. I would use Epsom salt sparingly or not at all on potted plants.
To complete the recipe, use club soda as a liquid fertilizer to bind the ingredients together. This carbonated drink contains micronutrients such as potassium and calcium that plants need. It's hard to say whether the trace minerals in club soda are enough to help plants grow, but they won't hurt. Club soda also contains a small amount of sodium, but unlike baking soda, I don't think it's enough to accumulate in the soil.
