how to remove mushrooms from your potting soil
Unfortuntely, we cannot just pick the mushrooms and toss them in the trash. If we do that, the mushroom's root system - aka the mycelium - will still be in the soil. Because the root systems are so miniscule, the best way to completelyget rid of mushrooms is to repot the plant. It’s important to get rid of as much of the original soil as possible to avoiding also transpotting the mycelium into the new planter. When repotting, hold the root ball under a steady stream of water. This will rinse the roots and loosen the rootball enough to get new soil into as much empty space as possible. You can put fungicide in the soil as a preventative measure, to kill any possible spores.
Preventing futher fungus growth
The best way to prevent mushrooms is to create an unfavorable environment for them. This starts with making sure that the soil of your plant is never extremely damp, or wet. Not only will too much moisture aid in the harmless growth of mushrooms, overwatering is a killer to your plants. Soil that is too damp promotes harmful bacteria and fungus in the soil, so be sure to check your soil consistently before watering!If your soil is high in nutrients, then mushrooms are more inclined to start growing. Most potting mix is composed of perlite, peat moss, and other organic matter like mushroom compost. If there are high amounts of organic matter the mushrooms will proliferate, but if you want to prevent mushrooms from growing, hold off on adding organic matter such as compost. Lastly, if there is high humidity it can trigger the growth of mushroom spores. Sometimes your plants really need the humidity, so there is no way around it, but if your plant can tolerate lower humidity and still thrive, lowering the humidity will also prevent the growth of mushrooms.
