How to Stop Mushrooms from Growing in Potted Plants

If you have potted plants in your home or garden, you may have encountered mushrooms growing in the soil. While mushrooms can be harmless, their presence can be unsightly and indicate potential issues with your plant’s soil or drainage. Here are some tips to help prevent and stop mushrooms from growing in potted plants:

1. Improve Drainage

Poor drainage is often the primary cause of mushroom growth in potted plants. Make sure the plant pot has proper drainage holes at the bottom and is not sitting in standing water. If the soil is waterlogged or poorly aerated, mushrooms can quickly sprout up. To improve drainage, try adding a layer of gravel or sand in the pot before filling it with soil. You can also mix some perlite or vermiculite into the soil to help retain moisture without drowning the roots.

2. Reduce Moisture

Adequate moisture is essential for healthy plant growth, but too much moisture can lead to fungal growth. Water your potted plants only when the top inch of the soil is dry. You can also reduce humidity by placing a fan near your plant or increasing the circulation in the room. Avoid overwatering or using a spray bottle to mist the leaves, as this can create a moist environment for mushrooms to thrive.

3. Remove Mushrooms

If you spot mushrooms growing in your plant’s soil, it is essential to remove them immediately. Mushrooms release spores that can quickly spread and lead to more fungus growth. Carefully dig up the mushroom and surrounding soil and dispose of it in a plastic bag. Do not compost the soil, as this can spread the spores to your other plants. If you notice more mushrooms growing in the pot, repeat the process until they stop appearing.

4. Use Fungicides

If the above methods fail to stop the mushrooms’ growth, you can use a fungicide to treat the soil. There are both synthetic and organic options available, so choose the one that best suits your needs. Be sure to follow the instructions on the label carefully and avoid using too much, as this can harm your plant’s health. Fungicides work by killing the existing fungus and preventing it from spreading.

5. Repot Your Plant

If your plant is suffering from severe fungal growth and the soil is contaminated, repotting may be the only solution. Remove the plant from its pot, wash the roots thoroughly, and dispose of the old soil. Inspect the root system for any signs of damage or decay and trim away any unhealthy roots. Replant the plant in fresh soil and a clean pot, making sure to improve the drainage and moisture levels.

In conclusion, mushrooms growing in potted plants can be a sign of underlying issues, but there are several ways to stop their growth. By improving drainage, reducing moisture, removing mushrooms, using fungicides, and considering repotting, you can help keep your plants healthy and fungus-free. Remember to monitor your plants regularly and address any issues as soon as possible to prevent fungi from taking hold.
