Why use a homemade bicarbonate fungicide for your plants?

When it comes to fungicides, homemade or natural options will always be better than chemical ones. The latter are usually composed of toxic elements that are harmful to certain microorganisms present in the substrate. Especially when we talk about garden plants and those grown for consumption.

Moreover, if chemicals reach water sources or underground bodies of water, they can cause pollution. Equally, they’re usually much more expensive than the ingredients you need to prepare your homemade mixture.

With bicarbonate, you can create a natural product that acts against pests and fungi.

The first thing to point out is that bicarbonate is a natural antacid with multiple applications. Specifically, it acts against fungi because it prevents the required conditions for their survival. This is despite fungi being able to survive in acidic environments.

Similarly, this natural element acts as a kind of poison against other microorganisms. So, as you can see, it’s highly effective against fungi and pests, benefiting your plants and supporting your efforts to have a healthy and beautiful garden.

Bicarbonate will become your best friend

Fungi and pests feed on your plants, leaving them without energy and nutrients to develop properly. When it comes to fungus, the more it breeds, the stronger it becomes, making it more difficult to eradicate. As such, always make sure you pay close attention to this issue and monitor the situation carefully.

When you identify stains, scabs, wilting and moldy layers on your plants, even if it’s slight, prepare your homemade fungicide based on baking soda or vinegar and put an end to the suffering.
