Why Are There Mushrooms Growing In My Monstera Plant

There are mushrooms growing in my monstera plant because the soil is staying too moist for too long, and the conditions are perfect for fungal growth.
 
When you see mushrooms popping up in your monstera’s pot, it’s not a sign that your plant is dying, but it is a clear signal that something is off with your watering or soil environment.
 
Mushrooms growing in your monstera plant are actually the fruiting bodies of a fungus that’s already living in the soil, and they usually appear when the top layer of soil remains damp and humid.
 
In this post, we’ll dig into why mushrooms are growing in your monstera plant, what it means for your plant’s health, and exactly how to fix the problem so you can keep your monstera thriving.
 
Let’s get right into the root of the issue, starting with the most common reasons mushrooms are growing in your monstera plant.
 

Why Mushrooms Are Growing In My Monstera Plant

Mushrooms growing in your monstera plant are almost always a sign of excess moisture and organic matter in the soil, and this is the main reason your monstera is hosting these uninvited guests.
 
The fungus that produces mushrooms is already present in most potting mixes, and it stays dormant until the conditions are just right for it to sprout.
 
When you overwater your monstera or don’t allow the soil to dry out between waterings, you’re essentially rolling out the welcome mat for mushrooms to grow.
 

1. Overwatering Creates The Perfect Mushroom Environment

The number one reason you’re seeing mushrooms growing in your monstera plant is that you’re watering too frequently or too much.
 
Monsteras like their soil to dry out partially between waterings, and when you keep the soil consistently soggy, the fungus in the soil gets the moisture it needs to produce mushrooms.
 
If you’re watering your monstera on a fixed schedule instead of checking the soil moisture first, you might be giving it more water than it actually needs.
 
When mushrooms appear, it’s a pretty reliable indicator that your monstera’s soil has been staying wet for days at a time, which is exactly what these fungi crave.
 

2. Rich Organic Soil Feeds The Fungus Behind The Mushrooms

Another reason mushrooms are growing in your monstera plant is that the potting mix you’re using is packed with organic matter that the fungus loves to break down.
 
Many commercial potting mixes contain compost, bark, coco coir, or other organic ingredients that are fantastic for your monstera, but they also give fungi a food source.
 
The mushrooms you see are the visible result of the fungus decomposing all that wood and organic material in the soil.
 
While this decomposition is actually healthy for the soil in small amounts, it leads to mushrooms growth when moisture levels stay high for too long.
 

3. Poor Air Circulation And High Humidity Contribute To Mushrooms

Monsteras love humidity as houseplants, but when you combine high humidity with poor air circulation around the pot, you’re setting up ideal conditions for mushrooms.
 
If your monstera is tucked into a corner with little airflow, the soil surface tends to stay damp longer, which encourages fungal growth.
 
Even if you’re letting the top inch of soil dry out, the deeper layers might still be wet enough to support mushrooms.
 
So when you ask why are there mushrooms growing in my monstera plant, the answer often involves the microclimate around your plant, not just your watering habits.
 

Are Mushrooms Growing In My Monstera Plant Harmful To The Plant?

Mushrooms growing in your monstera plant are not directly harmful to your monstera, and they won’t kill your plant or cause any diseases.
 
The fungus in the soil is a decomposer, which means it’s breaking down dead organic matter, not attacking living plant tissue.
 
In fact, the presence of mushrooms sometimes indicates that your soil is full of beneficial microbial life that’s helping to recycle nutrients.
 
However, the reason mushrooms are growing in your monstera plant, which is persistent overwatering, can absolutely harm your monstera if left unchecked.
 
Root rot is the real danger here, and it’s caused by the same overly wet conditions that allow mushrooms to sprout.
 
So while the mushrooms themselves are not a threat to your monstera, the environment that creates them definitely is, and that’s why you need to take action.
 

How To Get Rid Of Mushrooms Growing In My Monstera Plant

Once you’ve realized why mushrooms are growing in your monstera plant, the next step is to remove them and fix the underlying issue so they don’t keep coming back.
 
The good news is that getting rid of mushrooms is pretty straightforward, and the solutions are easy to apply at home.
 

1. Let The Soil Dry Out More Between Waterings

The most effective way to stop mushrooms from growing in your monstera is to change your watering routine.
 
Wait until the top two inches of soil feel completely dry before you water your monstera again, and even then, water thoroughly but less frequently.
 
You can use a moisture meter or just stick your finger into the soil to check, and this will help you avoid overwatering.
 
In most cases, reducing the moisture will cause the mushrooms to dry out and stop sprouting within a week or two.
 

2. Remove The Mushrooms And The Top Layer Of Soil

You can physically pick the mushrooms out of the pot, but to get rid of spores, it’s a good idea to remove the top inch or two of soil.
 
Wear gloves when you do this, and dispose of the soil and mushrooms in a sealed bag so the spores don’t spread to other plants.
 
After you remove the top layer, replace it with fresh, dry potting mix that’s less rich in organic matter if you want to reduce the chances of more mushrooms.
 
This won’t kill the fungus entirely, but it will help keep the visible mushrooms at bay.
 

3. Improve Airflow Around Your Monstera

You can also lower the humidity near the soil surface by increasing airflow around your monstera.
 
Place a small fan nearby on a low setting, or simply move your monstera to a spot where there’s more natural air movement.
 
If you have a humidifier running near your monstera, point it away from the pot so the soil doesn’t stay overly damp.
 
Better airflow will help the topsoil dry out faster, which is key to stopping mushrooms from growing.
 

4. Repot Your Monstera With Fresh, Well-Draining Soil

If mushrooms keep coming back no matter what, the cleanest solution is to repot your monstera with fresh potting soil.
 
Choose a mix that’s specifically designed for aroids, like a combination of coco coir, perlite, and orchid bark, which drains much faster than standard potting mix.
 
While you’re repotting, inspect the roots of your monstera for any signs of root rot, like brown or mushy roots, and trim those away before putting it in fresh soil.
 
This will eliminate most of the fungus in the old soil and give your monstera a healthier, drier home.
 

So, Why Are There Mushrooms Growing In My Monstera Plant?

Mushrooms are growing in your monstera plant because the soil is too wet and rich in organic matter, which creates the ideal environment for fungi to sprout.
 
This is almost always linked to overwatering, poor drainage, or a potting mix that holds onto too much moisture.
 
While the mushrooms aren’t dangerous to your monstera, they’re a clear warning sign that your plant is sitting in conditions that could lead to root rot.
 
By letting the soil dry out, removing the mushrooms, improving airflow, and possibly repotting, you can get rid of the mushrooms and keep your monstera happy.
 
So the next time you see mushrooms popping up, you’ll know exactly why mushrooms are growing in your monstera plant and how to fix it for good.
