Causes of white mold and fungus on soil

One of the most common causes for white mold and fungus on soil is overwatering. When the soil is constantly moist, it creates the perfect environment for mold and fungus to grow. Poor drainage can also contribute to this problem. 

Another cause can be poor air circulation. If your plants are crowded together or if the room they’re in doesn’t have good ventilation, it can create a humid environment that encourages mold and fungus growth.

Solutions for white mold and fungus on soil

The first step is to identify and address the underlying cause. If you’re overwatering your plants, cut back on watering and make sure your soil has good drainage. If poor air circulation is the problem, consider moving your plants to a more open are or using a fan to improve ventilation.

To get rid of the mold and fungus itself, you can try a few different solutions. One option is to spray the soil with a mixture of isopropyl alcohol mixed with water. Another option is to remove the affected soil and replace it with fresh soil. Generally I recommend the first option as it is important to fix the underlying cause. Simply replacing the soil can lead to not dealing with the underlying cause and therefore the problem will come back whether it is fresh soil or not. 

Preventing white mold and fungus on soil

The best way to deal with white mold and fungus on soil is to prevent it from happening in the first place! Avoid over watering and ensure your plants have air circulation. If you notice any signs of mold or fungus, address the problem to prevent it from spreading. 

In conclusion

White mold and fungus on soil can be a frustrating problem for gardeners, but it’s not impossible to deal with. By identifying the underlying cause and using the right solutions, you can get rid of the mold and fungus and prevent it from coming back. 


Happy Gardening!
