Showing your fiddle leaf fig some love is what being a houseplant owner is all about. Unfortunately, too much care through, say, giving it more water than it likely needs is a fairly common cause of certain problems arising, one of which is your fiddle leaf fig developing root rot.

This is a disease that can affect any plant, though root rot in a fiddle leaf fig is something that this plant is particularly prone to. The condition is brought on by the plant sitting for long periods in soil that is too wet and soggy. The abundance of moisture and lack of air pockets in the soil causes decay to set in as the roots don’t get enough oxygen and start to die.

So if you have been watching your fiddle leaf fig slowly start to decline, there’s definitely a chance that it has a case of root rot. Fortunately, if caught early enough and if swift action is taken, it’s more than possible to reverse any damage, save the healthy roots and lead your fiddle leaf fig to recovery.

Keep reading to find out just what you should do if faced with this situation – and how to prevent root root happening again in future.

How to Fix Root Rot in Your Fiddle Leaf Fig

What does root rot look like on fiddle leaf figs?

The leaves on a fiddle leaf fig with root rot will often form brown spots, but not always, so it’s best to actually check the roots. Signs of root rot on your fiddle leaf fig include heavy, compacted and wet soil with roots that are either brown or black, withered, mushy or, in extreme cases, completely rotted away. 

Sometimes, you may actually notice red spots on your fiddle leaf fig first before they start to become more brown.

It’s good to keep in mind that even a fiddle leaf fig that seems healthy at first glance and that is in soil that is appropriately drying out can still have root rot issues. While you may not be very keen to take it out of its pot, at least when you do so the signs of root rot in a fiddle leaf fig will be fairly easy to identify.

What’s the difference between healthy fiddle leaf fig roots vs root rot?

The main difference between healthy fiddle leaf fig roots vs root rot is that the roots with root rot will be brown or black, very wet and mushy and even sometimes rotted away. Healthy roots are usually white, cream or yellow. They’re also much firmer and able to be moved, compared to slimy, non-pliable roots with root rot.

What’s difficult about root rot is that your fiddle leaf fig itself may show signs of distress, but these can be similar to what it does when faced with other issues. For example, brown spots on your fiddle leaf fig are a certain sign of a problem – but just what that problem is can vary.

This is why actually checking the roots and comparing them to what they should look like in a healthy fiddle leaf fig is the best way to know if root rot is the problem you’re facing.

What do healthy fiddle leaf fig roots look like?

Healthy roots on a fiddle leaf fig are usually bright white, cream, or yellow in color. Older roots that are getting thicker and older can turn shades of brown but will still usually be much lighter in color than ones with rot.

It is also important to note that healthy roots, while they can bend and be flexed will still be ‘crisp’ to a certain extent. If you bend them too far, they will snap and break. Roots that are rotting will usually just bend, twist and start to break apart or even turn to mush between your fingers.

In brief, healthy roots on a fiddle leaf fig, and most plants in general, look much different from the black slimy mess you are likely to find in a plant dealing with root rot. You’ll definitely be able to tell the difference if you’re facing a case of root rot in your plant.

How do you fix root rot in a fiddle leaf fig?

Fiddle leaf fig root rot occurs because there usually is too much moisture in the soil due to overwatering. There could have been damage caused to the root system somehow that made it more susceptible to poor watering and fertilizing routines.

However, there is a chance to save your fiddle leaf fig from root rot if you can act fast and follow these steps

  1. Remove your plant from its pot to inspect the root system. What do the roots look like? What is the soil in the pot like? Look for the signs of root rot mentioned above and if your fiddle leaf fig has root rot, then you will want to take immediate action to try and save your plant.
  2. Gently remove as much of the soil from the root ball as possible. If needed, you can rinse off the root ball with room temperature water to clean off the muddy dirt. Once it has been cleaned off you can more closely inspect the roots.
  3. Remove any roots you find that are brown or mushy with a sharp pair of pruning shears or scissors to prevent the rot from spreading to other areas of the root system. You will want to remove the worst of the damaged roots, but, if at all possible, you likewise want to save as much of the root ball as you can so the fiddle leaf fig can more easily grow new roots and recover.
  4. Choose a bigger pot for your plant. With the dead and rotting roots removed, it is now time to get a different pot for replanting your fiddle leaf fig. Choose a fiddle leaf fig planter that’s larger than the one previously and make sure you get one that has drainage holes in the bottom if at all possible. If that is not an option then you may want to add a layer of graven to the bottom of your container. An inch or two layer can help to improve the drainage and provide a buffer that keeps the roots out of any standing water that forms at the bottom of the pot.
  5. Check that the pot isn’t too big. While you want space in the pot for new roots to grow, you also do not want a pot that is too oversized either. Too much empty soil in the pot will mean water is retained longer and the risk of over watering again is much, much higher. Ideally, you need a pot that is just 4 to 6 inches larger in diameter than what your plant was already in or larger than the root ball now that the dead roots have been trimmed away.
  6. After repotting, move your plant to bright, indirect light. It is important to make sure that your fiddle leaf fig gets enough light. Even with proper watering and drainage, fiddle leaf figs can suffer from root rot if they’re not getting enough light. Keeping it near a window where it can get morning or evening sun for long periods or at least a couple of hours of midday sun, is a good idea.
  7. Water your fiddle leaf fig once. Make sure the water drains out of the holes at the bottom of the pot. After that, wait. Do not water again until the root system has been able to dry out fully. If you are unsure how moist the soil deeper in the pot is, consider investing in a moisture sensor so you can learn how fast it will dry out and how often and how much you should be watering your fiddle leaf fig.

What is the best root rot fiddle leaf fig treatment?
