Root rot is a common challenge many indoor plant owners face, including myself. Early in my plant care journey, I had a few plants mysteriously decline despite what I thought was proper care. The culprit? Root rot.
Root rot happens when plant roots sit in soggy soil for too long, leading to decay. While it can seem intimidating at first, once you know the signs and how to treat it, you can often save your plant. In this post, I’ll guide you through the process of identifying root rot, fixing it, and preventing it from happening again—all from my personal experiences.
What is Root Rot?
Simply put, root rot occurs when your plant’s roots start decaying due to overwatering, poor drainage, or fungal infections. In healthy plants, roots are firm and white or light-colored. But when roots sit in waterlogged soil, they begin to suffocate. This stagnant environment is perfect for harmful bacteria and fungi, which start to attack the roots, turning them mushy, brown, or black.
It’s like the roots are drowning, unable to get the oxygen they need. As the rot spreads, the plant struggles to absorb water and nutrients, and if left untreated, it could eventually die.
Early Signs of Root Rot
I remember the first time I noticed something was wrong with my plant. It started with yellowing leaves, which I initially brushed off as normal aging. But then, the leaves began to wilt, and the plant just looked… off. If only I’d recognized the signs earlier, I could’ve prevented more damage.
Here’s what to watch for:
Above the soil:
- Yellowing leaves: This is one of the earliest indicators. If leaves turn yellow while you’re still watering regularly, root rot could be to blame.
- Wilting or drooping: Even when the soil is moist, if your plant is drooping, it’s a red flag that something is wrong beneath the surface.
- Stunted growth: If your plant isn’t putting out new leaves or growth despite being in its growing season, that could be a sign of root issues.
Below the soil:
- Mushy, discolored roots: Healthy roots are white and firm. If they’re brown or black and feel mushy, they’re decaying.
- Foul odor: A bad smell from the soil is a telltale sign of root rot.
- Soggy soil: Even if you haven’t watered in a while, if the soil still feels excessively wet, it’s likely the drainage is poor and causing rot.
How to Identify Root Rot: Step-by-Step Guide
When I suspected root rot in one of my plants, I decided to inspect the roots. I was nervous, but it’s essential if you want to confirm the diagnosis.
Here’s how to do it:
- Remove the plant from its pot: Gently pull the plant out of its pot. If the soil is compacted, you may need to loosen it with a gentle tap or tilt the pot.
- Inspect the roots: Look closely at the roots. Healthy ones will be white or light tan, while rotting roots will appear dark brown or black and feel mushy.
- Smell the soil: If the soil smells sour or rotten, that’s a strong indicator of root rot.
- Check moisture levels: Even if you haven’t watered in a while, if the soil is still soggy, the water isn’t draining properly, and the roots are suffocating.
Causes of Root Rot: What Went Wrong?
Root rot doesn’t just happen out of the blue. After dealing with it a few times, I learned that the causes are usually preventable.
- Overwatering: This is the most common culprit. When you water too frequently, the soil stays saturated, and roots can’t access oxygen.
- Poor drainage: Without proper drainage, water can collect at the bottom of the pot, creating the perfect environment for rot to set in.
- Incorrect soil mix: Using a heavy, compact soil that retains water can be disastrous for certain plants.
- Fungal infections: Sometimes, even with proper care, fungal spores in the soil can attack and decay roots. These spores thrive in overly wet environments.
I’ve made all of these mistakes at some point in my indoor gardening journey. But the good news is, once you know the cause, you can take steps to avoid root rot in the future.
How to Fix Root Rot: Action Plan
When I first encountered root rot, I wasn’t sure if my plant could be saved. Luckily, it wasn’t too late. Here’s how I managed to revive it:
- Remove the plant from the pot: Take the plant out and remove all soil from the roots.
- Trim the dead roots: Using sterilized scissors, cut away all the mushy, discolored roots. Don’t be afraid to prune heavily—leaving rotting roots will only spread the problem.
- Disinfect tools: To prevent spreading the infection, sterilize your scissors or any other tools you used before reusing them on other plants.
- Treat the roots: While optional, applying a fungicide to the healthy roots can help prevent further infection.
- Repot in fresh soil: Choose a well-draining potting mix that suits your plant’s needs. Ensure the new pot has good drainage holes.
- Adjust watering: After repotting, water sparingly until the plant shows signs of recovery. Place it in indirect light and monitor its progress.
This method worked for me on more than one occasion. One of my pothos plants, which looked like it was on its last legs, bounced back with some careful repotting and root trimming.

How to Prevent Root Rot in the Future
I’ve learned that prevention is the best cure when it comes to root rot. Here’s how to stop it from happening again:
- Use well-draining soil: Different plants need different soil types, but well-draining soil is key for preventing root rot.
- Choose the right pot: Make sure your pots have drainage holes. Without them, water has nowhere to go but to sit at the bottom.
- Water carefully: The “soak and dry” method works well for most indoor plants. Let the soil dry out between waterings and avoid watering on a strict schedule.

- Check moisture levels: I now rely on a moisture meter, but before that, I’d use the simple finger test—stick your finger about an inch into the soil. If it feels dry, it’s time to water.
Sometimes, seasonal changes can affect a plant’s watering needs. Read my guide on summer plant care to adjust your watering routine during hotter months.
Common Mistakes When Dealing With Root Rot
I’ve made my share of mistakes while learning how to deal with root rot. Here are a few common ones to avoid:
- Not checking drainage holes: It’s easy to forget, but even decorative pots need proper drainage.
- Watering too often: Even if the surface soil looks dry, the lower levels may still be moist. Always check before watering again.
- Not disinfecting tools: I once skipped this step, and the infection spread to another plant. Always clean your tools between uses.
Also, keeping plants clean also prevents infections; here’s how to keep your indoor plants clean and healthy.
Frequently Asked Questions (FAQs)
Q: What are the best soil types to prevent root rot?
A: Well-draining soils like cactus or succulent mixes are ideal for plants prone to root rot. You can also mix perlite or sand into standard potting soil.
Q: How do you know if a plant is too far gone?
A: If the majority of the roots are black, mushy, and falling apart, it may be too late. But if there are still some firm, white roots, the plant has a chance.
Q: Can root rot spread to other plants?
A: Yes, fungal infections can spread through contaminated tools, water, or soil. Always disinfect tools and keep infected plants separate.
Q: Is using a fungicide necessary to fix root rot?
A: It’s not always necessary, but fungicide can help prevent future fungal infections, especially if your plant is highly susceptible.
Final Thoughts
Root rot can be a scary diagnosis for your plants, but with quick action, most plants can recover and thrive again. The key is catching it early, removing the damaged roots, and adjusting your care routine to prevent it from happening again.
