How to Treat Plant Fungus with Baking Soda

Fungal issues are one of the most persistent problems that a plant can develop. While more common for outside plants, houseplants can also be subjected to fungal organisms that can damage or kill them. Often a pest infestation can weaken a houseplant and result in an infection.

If your plant has started showing signs of unusual spotting or has growths that are different colors than the plant, it probably has a fungus.

There are a variety of ways to treat fungal problems in outside plants such as fungicides. But, harsh sprays that contain chemicals aren’t the ideal way to treat plant problems inside your home.

There are ways to treat most plant issues that are completely safe for you, your children and pets. And, to treat fungus, baking soda is one of the safest.

Baking soda is a gentle and effective way to prevent fungus and to kill some forms of fungus that are established in your indoor and outdoor plants. Research has also proven that it can be highly effective in treating powdery mildew and some strains of black spot. But, best of all it is completely non-toxic. It’s also something that you probably already have on hand.

Baking Soda Spray Solution

You can make a baking soda spray by adding one teaspoon of baking soda to one quart of water.

Adding a few drops of mild detergent or insecticidal soap will help the baking soda solution stick to the leaves and stems. Just make sure that you don’t use a harsh detergent.

Baking Soda

Spray the entire plant from top to bottom making sure that you get underneath the leaves as well and allow the plant to dry.

If the fungus is really bad you may need to repeat the application again. You can even double the amount of baking soda to create a stronger solution. The process can be repeated when needed as a preventive treatment or if you see any more signs of fungus.

If after repeated applications you can get the fungus under control, then you may need to consider an alternative treatment.
