There are several ways to eliminate mold on plant soil. Some of these methods include using baking soda, potassium bicarbonate, cinnamon, and transplanting. For a quick and easy solution, try one of the methods below. A homemade remedy may also be necessary, so be sure to follow the instructions carefully. To get rid of mold, use a combination of these methods, or combine several of them. Your plant will thank you!

Baking soda

Using baking soda to get rid of mold on plant soil is an eco-friendly alternative to commercial fungicides. Not only is it cheap, but it is also more effective against many common plant diseases. It also works to maintain the pH level of the soil, deters insects, and enhances the taste of certain fruits and vegetables. In addition, baking soda also keeps the leaves and blooms of many plants fresh.

Another way to use baking soda to treat plant diseases is to mix it with water and apply it to the affected area. By sprinkling it on the plant, this natural solution reduces powdery mildew fungus on the leaves and minimizes the severity of fungal disease in plants. Baking soda can also be applied to potatoes, tomatoes, eggplant, chayote, and cabbage. To treat plant diseases with baking soda, simply add a few tablespoons to the water and spray the affected area. If the spray results in lowered flower quality, or leaf damage, reduce the amount of baking soda in the solution.

Although the use of baking soda to get rid of mold on plant soil can work, it should not be used on hot days or on plants that are already heavily infected. Aside from being a mildew killer, baking soda can also cause corrosion on metals. Baking soda should never be applied to plants if the weather is too hot. It could burn the leaves and cause damage to them.

Potassium bicarbonate

When you’re looking for an effective way to get rid of mold on plant soil, you’ll want to use a safe and natural fungicide such as potassium bicarbonate. This chemical can kill spores on contact and raise the pH level above 8.3, a level that is not conducive to fungal growth. To make your own solution, mix one part of potassium bicarbonate with three parts water. You can then spray the mixture onto your plants.

In an experiment with commercial gooseberry plants, researchers used potassium bicarbonate to reduce the incidence of powdery mildew. They conducted a randomized block design with four replicates and five plants in each. Observations were made on three central plants in each replicate, and spraying was done using a Solo knapsack sprayer with a 1mm hollow cone nozzle. The treatments were applied until runoff occurred.

Using potassium bicarbonate to get rid of mold on your plant soil will prevent the growth of new spores. The chemical has antifungal properties and is effective against many kinds of fungal diseases. It’s not as effective as conventional fungicides, but it can be a very effective solution. You can purchase potassium bicarbonate on Amazon, eBay, Alibaba, Walmart, and other online stores.


A natural anti-fungal, cinnamon inhibits the growth of mold and bacteria. Not only does cinnamon smell delicious, it will also prevent future mold infestations. Sprinkle cinnamon on the plant soil using a bottle with a hole in the lid or use it to add flavor to your seeds. Do not use a large dose, since you don’t want to burn your plants. It is best to test the solution on a small portion of the plant first.

For better results, apply a powdered cinnamon to the soil of plants. Sprinkle a little cinnamon on your plants’ soil and watch the problem disappear. Cinnamon contains natural fungicidal properties and works like sulfur. You can even use it as a rooting hormone for stem cuttings. This will double the growth rate of your plants and prevent them from rotting. However, it is not recommended for plants in plastic containers, since they can retain moisture.

Another natural anti-fungal is cinnamon powder. It can be purchased without breaking the bank and can be sprinkled on the soil in your plant pots. To apply the solution, mix half a cup of cinnamon powder with a quart of water. Sprinkle the mixture on the soil’s surface or spread it on the plants’ internal walls. Then, leave it in the sun for two days, allowing the cinnamon to do its magic.


The best way to prevent mold from growing on plant soil when transplanting is to use fresh, organic soil. You can purchase commercial potting soil or make your own using compost. Although you cannot prevent mold completely, you can reduce the risk of having moldy soil in your transplanting project by using fresh soil and avoiding any type of water that can sit on the soil. Here are some helpful tips:

Using an organic fungicide is another option. This solution is made from baking soda and half a teaspoon of liquid soap. You can also add horticultural oil to make the mixture stick to the mold. Once the mixture is applied, make sure to let the soil dry completely before watering the plant again. If the problem persists, isolate the plant for a few weeks until the soil conditions are right.

After thoroughly cleaning the plant soil, you can start the transplanting process. First, remove the top layer of dirt and the moldy soil from the pot. You can also try spraying the leaves of the plant with water and wiping them with a paper towel. Afterward, repot the plant. For best results, use organic soil for potted plants. After this, keep it in sunlight for a while until the soil dries.

Natural fungicides

There are several natural fungicides that can be used for a variety of plant diseases. Using Liquid Copper Fungicide (also known as CuSO4) can help combat the diseases on both garden and indoor plants. It can be applied to the infected soil or plant roots by simply mixing a half teaspoon in a liter of water. Make sure the soil is thoroughly wetted, since the solution needs to be effective in killing the fungus. Alternatively, you can use citric acid or lemon juice.

You can also use cinnamon powder. This substance will kill mold spores because of its larvicidal, insecticidal, and antifungal properties. Another natural fungicide is neem oil solution. It works to treat all kinds of infestations, including sooty mold. Use this mixture at a rate recommended by the manufacturer. Always read the label for recommended usage rates.

Baking soda is another natural fungicide you can use to get rid of mold and fungus from plant soil. This product has an alkaline pH and kills spores on contact. The solution can be applied directly to affected areas, including the soil beneath plants. Unlike chemical fungicides, baking soda does not have adverse effects on the health of humans or pets.

Organic matter in the soil

The white fluffy stuff on your plant soil is a harmless saprophytic fungus. This growth can occur because of poor soil drainage, too much water, contaminated potting soil, or a lack of sunlight. White mold spores are the most common symptom, and the problem is often easy to solve. You should remove all dead leaves and branches from your plants, as well as any organic debris, to create a healthy growing environment.

White mold is the least harmful of the three main types of fungus that can infect your plants. It typically only affects plants that are older and more resistant to disease. Unlike black mold, white mold can survive for a few days longer. However, mold spores are harmful to your health and can agitate allergies. It may also cause your plants to feel claustrophobic.

When it comes to removing mold on plant soil, the most common culprits are insufficient ventilation and high humidity. These conditions favor the growth of mold and other types of fungal growth. The best way to combat this problem is to learn more about different types of mold and how they can affect your plants. Generally, mold is most prevalent in spring and autumn when temperatures are cooler. As cold temperatures cause water to evaporate slowly, they are also ideal for fungal growth. Regardless of the type of mold that you see on your plants, the main thing to remember is to never create a dark environment. Plants need light, water, and fresh soil.


If you’ve ever noticed that your plants have mold growing on their soil, you may be wondering how to get rid of it. The good news is that there are several easy ways to eliminate this problem. One way is to remove the top layer of soil. This prevents the mold from multiplying and spreading. Another option is to use an acidic medium. You can use diluted citric acid or peat to prevent the mold from growing in the soil. You can also add charcoal pieces or sphagnum moss to filter out moisture from the air. Once you’ve done these simple steps, you can repot the plants or even remove the entire problem.

To avoid mold on your plants, you can use organic fertilizers. They will supply your plants with essential nutrients, but they should be applied at the right time of the year. Make sure to mix the right proportion of the organic fertilizer with your regular fertilizer. Too much fertilizer can cause mold on your plants. If you’re using organic fertilizer, make sure to follow the label. This product contains the necessary nutrients for soil bacteria to develop into the typical white mold.
