As a houseplant enthusiast, I’ve experienced the joy and satisfaction of watching my plants grow and thrive. However, I’ve also encountered a few challenges along the way, one of which is root rot. This common but often overlooked problem can be disastrous for houseplants if not addressed in time. In this article, I’ll help you recognize what root rot looks like, how to treat it, and most importantly, how to prevent it from happening in the first place. Your indoor plants will thank you!

Introduction to Root Rot in Houseplants


Root rot is a fungal disease that affects a plant’s root system, causing them to decay, turn brown or black, and become mushy. This disease can be caused by a variety of fungi, including Pythium, Rhizoctonia, and Fusarium. Root rot is typically triggered by overwatering or poor drainage, leading to an environment in which fungi can thrive. The excess moisture saturates the soil, depriving the roots of oxygen and allowing the fungi to multiply.


As the roots rot, the plant’s ability to absorb water and nutrients is compromised, leading to a range of symptoms such as yellowing leaves, wilted or stunted growth, and eventually, plant death. Identifying root rot early and taking action can save your beloved houseplants from this unfortunate fate.


Many times, rotting roots go unnoticed until the late stages. At that point, treating root rot and saving the plant becomes much more difficult.

Identifying Root Rot Symptoms and Signs


Recognizing the symptoms and signs of root rot is crucial for early intervention and treatment. Here are some common root rot symptoms to look out for:


  1. Yellowing leaves: One of the first signs of root rot is leaves turning yellow, often starting with the lower leaves and progressing upwards. This can also be a sign of other issues, so it’s important to examine the roots for further confirmation.
  2. Wilting: Despite receiving sufficient water, a plant with root rot may appear wilted and droopy. This is because the damaged root system cannot properly absorb water and nutrients.
  3. Stunted growth: A plant with root rot will often display poor or slow growth, as it struggles to obtain the necessary nutrients for growth.
  4. Foul smell: As the roots decay, they may produce a foul, musty smell. If you notice an unpleasant odor coming from the soil, it’s time to investigate the roots.
  5. Root appearance: Healthy roots should be white or light tan and firm to the touch. If the roots appear brown, black, or mushy, this is a clear indication of root rot.

What Does Root Rot Look Like in Different Houseplants


While the general symptoms of root rot are similar across different plants, it’s essential to know what root rot looks like in your specific houseplants, as this can help you identify the problem quickly.


  • Pothos: Pothos is a popular houseplant known for its hardiness and easy care. However, it can still fall victim to root rot. Pothos with root rot will exhibit yellowing leaves and a decline in overall health. Its roots will appear brown and mushy, often with a slimy texture.
  • Snake plant: Snake plants, also known as Sansevieria, can also develop root rot. Signs include yellowing leaves, soft and mushy leaf bases, and a foul smell coming from the soil. The roots will be brown or black and mushy.
  • Philodendron: Philodendron plants with root rot may have yellowing leaves that eventually turn brown and fall off. The roots will be dark brown or black and soft to the touch.
  • Spider plant: Spider plants are generally easy to care for, but they can experience root rot as well. Symptoms include yellowing leaves, wilted growth, and a foul odor coming from the soil. The roots will be dark and mushy.


Remember that while these descriptions can help you identify root rot, it’s essential to examine the roots to confirm the issue.

Causes and Contributing Factors of Root Rot


Understanding the causes and contributing factors of root rot can help you prevent it from occurring in your houseplants. The primary cause of root rot is overwatering and poor drainage, leading to excess moisture in the soil. Other factors that can contribute to root rot include:


  1. Poorly draining soil: Heavy, water-retaining soils can promote root rot by keeping the roots constantly wet.
  2. Container size: Using a container that is too large for your plant can lead to soil retaining too much moisture, increasing the risk of root rot.
  3. Lack of aeration: Compacted soil or a lack of air pockets in the soil can lead to oxygen deprivation, promoting fungal growth.
  4. Contaminated tools: Using contaminated tools or containers can introduce fungi into the soil, increasing the risk of root rot.

How to Treat Root Rot: Effective Root Rot Treatment Methods


If you’ve identified root rot in your houseplants, it’s crucial to act quickly to save them. Here are some effective root rot treatment methods:


  1. Remove the affected plant from its pot and gently remove the soil from the roots.
  2. Using a sterilized pair of scissors or pruning shears, trim away any brown, black, or mushy roots. Be sure to sterilize the tool after each cut to prevent spreading the infection.
  3. After trimming the affected roots, rinse the remaining healthy roots with water to remove any remaining fungi.
  4. Repot the plant in a clean container with fresh, well-draining soil. You may also want to consider adding a fungicide to the soil to help combat any remaining fungi.
  5. Water the plant sparingly, allowing the soil to dry out between waterings to prevent further root rot.


Pro Tips:


  • Combine one part 3% hydrogen peroxide with two parts water. Pour this over the plant’s roots or use a spray bottle to spray it on. I sometimes dip the roots in a cup containing the diluted hydrogen peroxide. This will kill the fungus and associated bacteria.
  • Use a mixture of 5 ml (1 teaspoon) of 3% hydrogen peroxide in 240 ml (one cup) of water to spray on your plants. This works with healthy plants, too, as a means of keeping bacteria and fungus controlled. (full article here)

Help! I think my houseplant has root rot. Can I save it?

Don’t panic! While root rot can be a serious issue for houseplants, there are steps you can take to potentially save your green friend. First, remove the plant from its pot and carefully examine the roots. Trim away any mushy or discolored roots with clean, sharp scissors. Next, repot the plant in fresh, well-draining soil. Make sure the new pot has drainage holes to prevent water from pooling at the bottom. Lastly, adjust your watering routine. Let the soil dry out slightly between waterings and ensure you’re not overwatering. With a little care and patience, your houseplant may bounce back!

What are the common signs of root rot in houseplants?

Recognizing the signs of root rot early on can greatly increase your chances of saving your plant. Keep an eye out for wilting leaves that don’t respond to watering, yellowing or browning of leaves, stunted growth, and an unpleasant, musty odor coming from the soil. If you notice any of these symptoms, it’s important to act promptly. Checking the roots is a good next step. Gently remove the plant from its pot and inspect the roots for discoloration, mushiness, or a foul smell. Catching root rot in its early stages gives you a better chance of treating it effectively.

How can I prevent root rot in my houseplants?

Prevention is key when it comes to root rot. Here are some tips to help you keep your houseplants healthy and free from this common issue. First and foremost, ensure that your plants are potted in well-draining soil and containers with drainage holes. This allows excess water to escape and prevents water from stagnating around the roots. Be mindful of your watering habits and avoid overwatering. Before watering, check the moisture level of the soil by sticking your finger about an inch deep into the soil. If it feels dry, it’s time to water. Additionally, avoid using saucers or decorative outer pots that can trap excess water. Finally, provide adequate light and ventilation for your plants, as poor air circulation can contribute to root rot.
