This compound, so common in our kitchens, hides qualities that go far beyond its culinary applications. In other words, just like in the kitchen, bicarbonate proves to be a harmonizing tool, offering a simple and ecological method for maintaining plants.
One of the biggest challenges in growing plants is managing fungal diseases. Baking soda is a hero in this regard, thanks to its ability creating adverse conditions for the development of fungi.
The secret lies in its alkaline nature, which when applied to plants in a diluted solution (one teaspoon per liter of water), raises the pH of the leaf surface. So, this makes the environment inhospitable to invaders, protecting the plants and preventing you from having to resort to chemical fungicides.
It is not only against fungi that sodium bicarbonate shows its effectiveness. In other words, in the fight against pests such as aphids, mealybugs, flies and various larvae, it can also be extremely useful. A solution that mixes baking soda, vegetable oil and a little mild soap can act as a natural repellent. After all, it creates a physical and chemical barrier against these small invaders.
The application of this mixture must be done with caution, avoiding exaggerations that could harm the plant. However, in the right measure, it becomes an excellent option for keeping your garden pest-free without harming the environment.
Finally, the issue of soil pH is essential for plant health. Some specimens, especially those that bloom with vibrant colors, prefer slightly alkaline soil. Therefore, if the soil in your garden is too acidic, sodium bicarbonate can be used to adjust the pH, raising it in a gentle and controlled way.
By doing this, you will not only be favoring the plants that prefer these conditions, but also avoiding the excessive availability of heavy metals that can be toxic to plants.
