Fiddle Leaf Fig Brown Spots
Brown spots on fiddle leaf figs have four main causes:
- Root rot
- Bacterial infection
- Insect damage
One of the most common concerns that fiddle leaf fig owners face is how to fix fiddle leaf fig brown spots on the beautiful leaves of their plant. It’s disheartening to see brown spots spoiling the beautiful large green leaves of your ficus lyrata, and the condition can be frustrating and confusing because it takes a bit of experience to determine what is causing the brown spots on your fiddle leaf fig.
It’s important to diagnose the problem quickly and treat your plant to help it fully recover. There are actually four main causes of brown spots:
- Root rot
- Bacterial infection
- Insect damage
When beginning to look for the cause of the brown spots, here are a few questions to ask yourself:
- Is your fiddle leaf fig too dry?
- Are you overwatering your fiddle leaf fig?
- Is it getting too much sun?
- Is it not getting enough light?
And here are some questions to get you started with diagnosing the specific cause of the brown spots:
- Do the brown spots start at the edge of the leaf or in the center of the leaf?
- Are they very dark brown (almost black) or lighter brown (more tan in color)?
- Do you see many spots on each leaf or just one large brown area?
- Do the brown spots result in the leaves eventually falling off?
- Are they affecting older leaves near the bottom of your plant or younger new leaves near the top of your plant?
Once you’ve taken a good look at your brown spots and reviewed the characteristics, it’s time to figure out what the cause is.
I’ve found that the best way to tell what’s causing your brown spots is to review several photos of the most common conditions to identify the problem with your plant. Here’s your definitive photo guide to brown spots in fiddle leaf figs!
Fiddle Leaf Fig Brown Spots From Root Rot
Arguably the most common cause of brown spots in a fiddle leaf fig is root rot from overwatering.
Root rot is a fungal infection that takes place when the roots sit in water for too long and don’t have adequate drainage. Not enough sunlight can make this problem worse. Too large of a pot can also cause your plant’s roots to remain too wet between waterings.
One interesting feature of root rot is that it tends to affect older leaves first, as your plant attempts to save the newer growth that is closer to valuable sunlight. The lower leaves of your plant are the ones root rot will affect first, so begin your search there.
Fiddle leaf fig roots in particular need fast-draining soil and ample drainage. If your fiddle leaf fig has brown spots from root rot, you’ll want to act quickly. Try our Root Rot Treatment to treat your infection before it spreads, and use our Houseplant Leaf Armor to protect your fiddle leaf fig from bacteria, fungus, and insects.
Here are the telltale signs of root rot:
- Very dark brown or black spots that spread throughout the leaf over days or weeks
- Dark brown spots at the base of your leaf
- Leaves that are dropping off of your plant
The brown spots may start as small black spots, then will get larger, until the entire leaf drops. If you think your plant has root rot, you can use a moisture meter like this one to take a moisture reading near the bottom of the roots. If your reading is very wet, root rot is likely the cause.

How to Treat Brown Spots Caused By Root Rot
Generally, root rot is very treatable, especially if you catch it early.
Since root rot is generally a problem of poor drainage, you’ll want to address your drainage immediately. Make sure you have a well-draining container, fast-draining potting soil, and that you aren’t watering too frequently.
The next thing you’ll want to do is assess the damage. If there are just a few brown spots on the leaves, you do not need to repot your plant. Let your plant dry out for two weeks or more until the roots have adequate time to recover. Remove the affected leaves and make sure your plant has enough sunlight.
If you’re not sure whether your plant is getting too much water, you can use a moisture meter to make sure the roots are drying out between waterings. Then your plant should recover with proper drainage and watering. Take a look at our Ultimate Watering Guide here to learn more about proper watering.
However, if the damage is severe or spreading rapidly, you’ll want to perform root surgery and repot your fiddle leaf fig.To do this, remove your plant from its pot and hose down the root ball. Cut away any brown, mushy roots. Make sure you have proper drainage and repot with fast-draining house plant soil like this. Follow good watering practices in the future to make sure the problem doesn’t reoccur.
Fiddle Leaf Fig Brown Spots From Bacterial Infection
Bacterial infections in fiddle leaf figs can be very frustrating and hard to treat.
The problem mimics the symptoms of brown spots from root rot, but is often more difficult to fix.
Here are the signs of a bacterial infection:
- Brown spots will be lighter in color than from root rot, ranging from tan to dark brown.
- Spots will form across the leaf, not necessarily at the edges or the base of the leaf as with root rot.
- Your plant may drop leaves both at the bottom and top of the plant.

How to Treat Brown Spots From a Bacterial Infection
Unfortunately, this is one of the hardest conditions to treat in a fiddle leaf fig.
The key is to treat the spots as early as you can before the damage spreads too far. The treatment is similar to treating root rot: you’ll want to make sure your plant’s roots dry out between waterings and that it’s getting plenty of sun.
If the damage is not severe, cut off all of the leaves with brown spots and repot your plant with fresh, sterile soil in a container with good drainage. Give it plenty of light and go easy on watering until it recovers.
Consider using our Leaf Armor, which was designed to protect your houseplant from not just bacteria, but also from insects and fungus.
Another good way to treat bacterial infections is to put your fiddle leaf fig outside in the shade to recover, depending on your climate. Fresh air, plenty of sunlight, and warm conditions can help your plant recover. Just be sure that your plant is protected from direct sunlight and doesn’t get too cold (less than 50 degrees) or too hot (greater than 95 degrees).
However, if your plant has more than 50% of the leaves affected by brown spots and the condition is spreading, you may be better off starting over. Discard the plant and start fresh with a healthy specimen. You may want to contact the store where you purchased your plant to see if they’ll replace it.
Fiddle Leaf Fig Brown Spots From Dryness
Very dry fiddle leaf fig plants can quickly develop brown spots, which typically are more tan in color than brown, and start at the edge of the leaf and spread inward.
The relative humidity for your plant should be between 30-65%, so if your home humidity is much lower or your plant is near a heater, you may need to create more humidity for your fiddle leaf fig by misting or changing locations.
Brown spots can happen slowly or very rapidly on a hot day, like for the fiddle leaf fig pictured below, which was left outdoors on a 110-degree day. This leaf completely dried out in less than 12 hours.
In this next photo, you can see a completely dry plant that was left without water for over two months when its owner went on vacation. A telltale sign of dryness is the drooping of the leaves, which have lost their turgor pressure from lack of water.
Using a moisture meter like this one lets you know when your plant is thirsty. Consistent adequate water is essential for your fiddle leaf fig to thrive!

How to Treat Brown Areas on a Dry Plant
The basic treatment for a dry plant is making sure you’re not underwatering. Your plant needs to be watered when the top inch of soil has dried out, any more and you risk not giving your plant enough water. If you notice soil shrinkage, you’ll want to repot your plant to make sure your root ball is getting adequate water. Repotting is easy, and there are just a few simple steps to follow to do it successfully.
If your fiddle leaf fig is in an environment with low humidity or near a heater, consider moving it to another location. Water regularly (try once a week) and monitor your plant to make sure it’s getting enough moisture.
You can try misting every one to three days or using a humidifier near your plant if your home is very dry, though this is not typically necessary unless a heater is running near your plant. After treating your plant for dryness, get your plant on a good watering schedule and you should begin seeing new growth in a week or two as long as the plant itself is still alive.
Brown Spots on Fiddle Leaf Fig Leaves From Insect Damage
Insect damage in a fiddle leaf fig plant is thankfully less common.
The giveaway to diagnose insect damage is small dark spots that damage the plant leaves that turn into holes in the leaves. This happens more commonly in the new, tender growth.
You can also look out for any insects on your plant (use a magnifying glass) or any white or gray insect webs. If you find any evidence of insects living on your plant, you’ll know this is the cause of your brown spots.
How to Treat Brown Spots from Insect Damage
Insect infestations are easy to treat.
Use our Leaf Armor, designed for houseplants to protect against insects, bacteria, and fungus. (This product works just like neem oil but without the unpleasant smell! As an added bonus, the Leaf Armor also cleans and adds shine to your houseplant’s leaves.)
Spray all the leaves of your fiddle leaf fig thoroughly. Turn each leaf to spray the underside and don’t forget where the leaf meets the stem. Wait two weeks, inspect again, then repeat the spraying process if needed.
Fiddle Leaf Fig Brown Spots From Physical Trauma
Brown spots on a new plant that show up a week or so after you move your plant are often from physical trauma. This is because the large leaves on a fiddle leaf fig are often damaged during a move and the bruises left of the plant will turn brown over time.
Often, these spots look like cracks or tears. Brown spots from physical trauma are certainly a bummer, but they do not need treatment and your plant will generally recover very well. The telltale sign of brown spots from physical trauma is that they appear on an otherwise very healthy leaf and plant.
To treat brown spots from physical trauma, you just need to give your plant some time and TLC to help it heal. You can remove damaged leaves if you want, but if the problem is just physical trauma, a damaged leaf shouldn’t affect your indoor plant’s health.
Fiddle Leaf Fig Brown Spots From Sunburn
If your plant gets too much direct sunlight, it can get a sunburn, which manifests as light brown spots that sometimes look bleached.These spots will appear predominantly on the top leaves and can even show some red and yellow coloring, depending on how recent the burn is. The leaves should be removed by pruning, and the plant should be relocated to a more protected location with a lot of indirect light, and minimal direct sunlight.
Even though fiddle leaf fig leaves are susceptible to sunburn, you are able to acclimate your plant slowly to direct sunlight. Read more and watch the following video about how best to acclimate your plant to full sun.
To treat your plant’s brown spots from a sunburn, you will need to remove the affected leaves with sharp, clean pruning shears, and remove the cause of the sunburn by moving the plant to a spot that gets less sun. Do not prune off all of the leaves. Try to only take off about 10% of the leaves at a time to prevent your plant from going into shock.
