How to Destroy Fungus in Soil
Fungi love dark and wet places, making over-watered areas of soil like a vacation spot for them. Pairing an over-watered area with the heat caused from nature (or other heat sources) creates a spa-like setting for the fungus. So what happens when the fungus has already multiplied and the plant is now suffering? Unfortunately, there is no way to completely kill the fungus. Instead, preventing it from breeding and spreading is the only way to stop it. Does this Spark an idea?

Spray the affected soil and plants with a mixture of baking soda and water. The mixture should be: 1 tbsp. of baking soda per gallon of clean water. For more stubborn areas, you can increase the baking soda to 2 tbsp. Additionally, 1 tsp. of vegetable oil can be added to the solution. This will help the mixture stick to the leaves of the plant.
