Do you know how to get rid of fungus in fiddle leaf fig soil? Were you aware that your soil could even get fungus?
Has this happened to you? You go to water your fiddle and notice mushrooms growing in the potting. Or maybe you see white mold growing on top of your soil. Or you might see unexplained brown spots on your leaves.
These are all signs of fungus growing in your fiddle leaf fig’s soil and possibly the roots.
If left untreated, it can lead to fungal root infection, which is very dangerous for your tree!
How to Prevent Fungus in Fiddle Leaf Figs
Prevention is always best, so let’s talk about how to stop fungus from growing in your plant’s soil in the first place.
Fungus likes to grow in dark, damp conditions.
Giving your plant the proper lighting and correct watering routine is the best thing you can do to prevent fungus and encourage the best overall health for your tree. (We also recommend our Houseplant Leaf Armor to protect your plant’s leaves from fungus, bacteria, and insects. As an added bonus, it also cleans and adds shine to the leaves.)
Fungus is a sign of over-watering, which can cause root rot, so you definitely want to nip it in the bud. (Treat root rot with our Root Supplement.)

Make sure your plant gets plenty of bright, indirect sunlight.

Check your other plants carefully
Like bacteria, fungus can spread from plant to plant.
Before bringing a new plant home, make sure to check it for signs of fungal growth or infection.
Keep new plants away from your existing houseplants for a few weeks when you first bring them home, and if you notice fungus growing on one of your houseplants, get it away from your other plants to prevent the fungus from spreading.
How to Get Rid of Fungus in Fiddle Leaf Fig Soil
So how do you deal with the fungus that’s already there? Here are our favorite tips.
Carefully remove visible fungus
Use a spoon to scoop off any visible fungus from the top of the soil. This won’t prevent fungus from growing beneath the surface, but it can help if it’s just mild fungal growth.
Remember that fungus and mushrooms like dark, damp conditions. Conversely, good light can help your plant fight off a fungal infection and stop one from forming in the first place.
Move your fiddle closer to a bright window, but make sure the sun’s rays don’t actually hit the leaves (make sure the tree never casts a shadow.)
If you don’t have the right light conditions in your home, consider investing in a grow light. (We recommend these grow lights.)
Cinnamon or another antifungal treatment
Cinnamon is naturally antifungal, so it can prevent fungus from growing and even get rid of mild fungus on the soil’s surface.
Sprinkle a little on the top of your soil to discourage fungus from growing or spreading.
Put your plant outside
This is a situation where it might be a good idea to put your plant outside.
The fresh air and extra light can jump-start your plant’s immune system and help the soil dry out faster than it would inside. Just make sure not to put your tree in full sun.
(Full disclosure: Some fiddle leaf figs can handle full sun, but most need to be acclimated to it.)
If you live in an area with warm (but not hot) temperatures, try putting your tree outside in the shade.
Keep an eye on your tree for signs of drying or burning, especially if you live in a dry climate.
Fiddle leaf figs can handle more sun and hotter temperatures with high humidity, but if you live in the desert, you risk drying out your tree.
Keep very close tabs on your fiddle if this is the case.
If the problem is severe, repot the plant in fresh soil before the fungus causes an infection in the roots.
Gently remove as much of the old soil from the roots as possible. If you notice any mushy roots, remove them. If you see fungus growing on the roots, prune those as well.
Repot into a clean pot with drainage holes and a fast-draining soil to prevent over-watering and fungal growth in the future.
