How to Kill Mushrooms in Potted Plants

If you have potted plants in your home, you may have noticed mushrooms growing in the soil. While mushrooms are not necessarily harmful to your plants, they can be unsightly and may indicate that the soil is not healthy. Here are some effective ways to kill mushrooms in potted plants.

Remove the Mushrooms

The first step in getting rid of mushrooms in potted plants is to physically remove them. Use a small trowel or your hands to carefully dig around the base of the mushroom and pull it out of the soil. Be sure to wear gloves to avoid getting any potential toxins on your skin.

Adjust the Soil pH

Mushrooms thrive in soil that is slightly acidic, so adjusting the pH can help to prevent their growth. You can use a soil pH tester to determine the current pH level of your plant's soil. If the pH is below 6, add some lime to the soil to raise the pH level. If the pH is above 7, add some sulfur to the soil to lower the pH level.

Reduce Moisture

Mushrooms need moisture to grow, so reducing the amount of water your plants receive can help to prevent their growth. Be sure to only water your plants as needed, and avoid overwatering. Additionally, consider adding some perlite or sand to the soil to improve drainage and reduce moisture retention.

Use Fungicides

If the above methods are unsuccessful, you can try using a fungicide to kill mushrooms in potted plants. Look for a fungicide that is labeled for use in potted plants, and follow the instructions carefully. Be sure to wear gloves and avoid touching your face or mouth while using the fungicide.

Replace the Soil

If the mushrooms continue to grow despite your efforts, it may be necessary to replace the soil entirely. Carefully remove the plant from the pot and gently shake off any excess soil. Discard the old soil and replace it with fresh, sterilized soil. This can help to prevent the growth of new mushrooms.

In conclusion, mushrooms can be a sign of unhealthy soil, and their presence can be unsightly. By implementing the methods above, you can effectively kill mushrooms in potted plants and promote the health of your plants.
