There is a mushroom growing in my aloe plant because the soil is staying too moist for too long.
If you’ve spotted a mushroom growing in your aloe plant, it’s a clear sign that your watering habits and soil conditions are out of balance for a desert-loving succulent.
A mushroom growing in aloe isn’t harmful to the plant itself, but it does tell you that the environment is perfect for fungal growth, which means your aloe might be at risk of root rot down the line.
In this post, we’ll dig into exactly why a mushroom growing in aloe happens, what it means for your plant’s health, and how to fix the conditions so you can prevent future mushrooms.
Let’s get to the root of this fungal mystery.
Why There Is A Mushroom Growing In My Aloe Plant
When you see a mushroom growing in your aloe plant, the most common reason is that the potting mix is holding onto way too much moisture.
Aloe vera plants are native to arid regions, so they expect their roots to dry out completely between waterings.
But mushrooms thrive in damp, decomposing organic matter, which is exactly what your potting soil becomes when it stays wet for extended periods.
Here’s what’s really going on beneath the surface:
1. Overwatering Is The Number One Culprit
If you’re watering your aloe on a strict weekly schedule, stop right now.
A mushroom growing in your aloe plant is almost always a direct result of overwatering.
When the soil never fully dries out, fungal spores that were already in the potting mix wake up and start colonizing the surface.
These spores come in with commercial potting soil, and they stay dormant until the moisture levels are just right.
Your aloe might only need water every two to three weeks, especially if it’s in a pot without drainage holes.
When you keep the soil soggy, you’re basically rolling out a welcome mat for mushrooms.
2. The Potting Mix Is Too Dense And Water-Retentive
Aloe plants need a gritty, fast-draining cactus mix, not regular garden soil or all-purpose potting mix.
If you used a dense mix that holds water like a sponge, a mushroom growing in your aloe plant is much more likely to appear.
Regular potting soil contains peat moss and compost, which break down over time and create exactly the kind of organic buffet mushrooms love.
The fix is to repot your aloe into a mix of coarse sand, perlite, and a small amount of potting soil.
This allows water to flow right through and keeps the top layer dry, which mushrooms can’t tolerate.
3. Poor Drainage And Lack Of Airflow
Your pot needs at least one drainage hole at the bottom.
If water sits in the bottom of the pot with nowhere to go, that stagnant water creates a mini swamp.
And a mushroom growing in aloe loves a swampy, humid microclimate.
Also, consider where your aloe is placed.
If it’s in a dark corner of your home with no air circulation, evaporation slows way down.
Mushrooms pop up when humidity levels are high and airflow is nearly zero.
Move your aloe to a bright windowsill and make sure air can move around the pot.
4. High Humidity In The Home Environment
If you live in a humid climate or run a humidifier in the same room, your aloe’s soil will stay wetter than it should.
This is especially true during the cooler months when indoor humidity can spike.
A mushroom growing in aloe is basically telling you that the air around the plant feels like a rainforest, not a desert.
Try moving the plant away from steamy kitchens or bathrooms and into a drier room.
You can also place a small fan nearby to keep the air moving and the topsoil dry.
5. The Mushroom Came From Contaminated Potting Mix
Sometimes, the mushroom growing in your aloe plant has nothing to do with your watering routine.
Commercial potting mixes are not sterile.
They contain beneficial fungi and bacteria, and occasionally, they carry mushroom spores as well.
If you just repotted your aloe and suddenly see a mushroom, it likely came from the bag of soil.
The spores were always there; they just needed the right moisture to sprout.
You don’t need to panic, just scrape off the mushroom and let the soil dry out completely.
Is A Mushroom Growing In My Aloe Plant Dangerous?
If you’ve been freaking out about the mushroom growing in your aloe plant, take a deep breath.
The mushroom itself is not going to eat your aloe or kill it instantly.
Mushrooms are the fruiting bodies of a larger underground fungus that feeds on decaying organic matter in the soil.
They don’t attack living plant tissue like some pathogenic fungi do.
That said, their presence signals that the soil is staying too wet, and that’s the real danger.
Wet soil leads to root rot, and root rot will absolutely kill your aloe plant.
You can also gently remove the mushroom, but understand it will come back until you fix the moisture problem.
If you have pets or small children, you’ll want to remove any mushrooms immediately because you can’t identify if they’re toxic just by looking at them.
What Kind Of Mushroom Is It?
Most mushrooms that appear in houseplants, including a mushroom growing in aloe, are from the Leucocoprinus genus.
They look like small yellow or brown umbrellas with gills underneath.
These are common in potted plants because they thrive on woody material in the soil.
It doesn’t help to know the exact species because the treatment is the same.
Just focus on pulling them out wearing gloves and fixing the wet growing conditions.
How To Prevent A Mushroom From Growing In Aloe Again
Now that you know why a mushroom growing in aloe happens, here’s how to stop it for good.
1. Water Only When The Soil Is Completely Dry
Stick your finger two inches into the soil.
If it comes out completely clean and dry, then it’s time to water deeply.
If you feel any moisture at all, wait another few days.
Mushrooms cannot survive in dry soil.
A mushroom growing in aloe is basically proof that you are watering too often.
So, cut your watering frequency in half and see how happy your aloe will be.
2. Repot With A Gritty Succulent Mix
Slide your aloe out of its current pot and shake off all the old damp soil.
Repot it with a fresh cactus mix, and add extra perlite or pumice to increase drainage.
Make sure the pot has drainage holes and isn’t nested inside a decorative pot that catches water.
This alone will stop any future mushroom from growing in your aloe.
3. Scrape Off The Top Layer Of Soil
The mushroom spores live in the top few inches of soil.
Carefully scoop off about two inches of the topsoil and replace it with fresh, dry cactus mix.
This removes the bulk of the fungal material while keeping your aloe roots undisturbed.
It’s a quick fix, but you still need to adjust watering after that.
4. Improve Light And Airflow
Move your aloe to a south or west-facing window where it gets bright, indirect sunlight.
More light means more evaporation and drier soil.
You can also point a small fan at it for a few hours a day.
The drier the surface, the less likely you will ever see a mushroom growing in aloe again.
So, Why Is There A Mushroom Growing In My Aloe Plant?
There is a mushroom growing in my aloe plant because the growing conditions are too wet, too humid, or both.
The mushroom is just a symptom of overwatered, compacted soil that stays moist long after you’ve watered.
By fixing your watering habits, repotting into a gritty mix, and boosting airflow, you can easily get rid of mushrooms for good.
Your aloe will heal, grow stronger, and go back to being the low-maintenance desert companion you always wanted.
