Using Baking Soda to Solve Common Plant Issues Naturally
Combat Fungal Infections on Plants Using a Baking Soda Spray
Diseases caused by fungi, such as black spots and powdery mildew, can affect a wide variety of plants, although tomatoes and roses are particularly susceptible. By altering the pH of the leaves, baking soda creates an environment that is unfavorable for the growth of fungal spores. A straightforward spray can effectively prevent and treat infections caused by these spores.
To prepare it, mix together one tablespoon of baking soda and one gallon of water from the container. Include a few drops of liquid dish soap in the solution to improve its ability to adhere to the leaves. After giving it a little stir to prevent an excessive amount of foaming, transfer it to a spray bottle when you want to make application more convenient.
The mixture should be applied early in the morning on a dry day to ensure that the leaves dry before the sun goes down. Coat the affected leaves thoroughly on both sides, paying special care to any areas that are white or dark in color. Repeat the process every seven to ten days until the symptoms disappear to prevent the accumulation of soil alkalinity.
The adoption of this method is ideal for organic farming because it has a lower influence on the surrounding environment. Test the solution on a small part of the plant first, as begonias and other delicate species may react badly. Keep a watch out for any signs of leaf withering or burning on the plants, and adjust the concentration as required.
