As gardening enthusiasts and horticulturists, we’ve gathered valuable insights and knowledge to help you overcome this common problem that affects Monstera plants.

What is Monstera Root Rot?

Root rot in Monstera plants occurs as a result of fungal infection, which can be attributed to excessive watering or inadequate soil drainage. This leads to damage to the plant’s root system. Due to this, the plant can face many problems. These include sudden discoloration of leaves, reduction in plant productivity, and wilting. If left untreated, this condition can severely impact the well-being of the Monstera plant and potentially lead to its demise.

Visual Symptoms

Detecting root rot in Monstera plants can be challenging as the symptoms often manifest above the ground. However, there are several signs to look out for that can indicate the presence of this condition:

  • Yellowing leaves: The first one is leaves turning yellow. Root rot often initiates in the lower section of the plant and could be an indication of its presence.  As the infection progresses, the yellowing spreads throughout the foliage.
  • Wilting or drooping leaves: Root rot compromises the plant’s ability to absorb water, causing the leaves to wilt or droop, even when adequately watered.
  • Root discoloration: Healthy Monstera roots should appear firm and white. The presence of dark, mushy, or discolored roots is typically indicative of root rot.

Performing a Root Check

Performing a Root Check

To confirm whether your Monstera plant is affected by root rot, you can perform a simple root check:

  1. Carefully remove the plant from its pot. After that, gently brushing off the soil to expose the roots.
  2. To assess the root health, carefully examine them for any indications of decay, such as a foul smell, slimy texture, or dark discoloration.
  1. Healthy roots will appear firm and white while rotting roots will be mushy, brown, or black.

Causes of Monstera Root Rot

Understanding the causes of Monstera root rot is crucial for effective prevention. The following factors contribute to the development of this fungal infection:

  1. Overwatering: Excessive watering or watering too frequently can lead to waterlogged soil. It can deprive the roots of much-needed oxygen.
  1. Poor drainage: If the potting medium or soil does not provide adequate drainage, excess water can accumulate around the roots. It creates an ideal environment for root rot.
  1. Incorrect pot size: When planting your Monstera, it is important to avoid using a pot that is excessively large, as it can lead to moisture retention, thereby elevating the risk of root rot.
  1. Lack of sunlight:  Insufficient exposure to natural light can weaken the plant’s immune system. Not getting enough sunlight makes it more susceptible to infections including root rot.

Preventing Monstera Root Rot

Now that we have explored the causes and symptoms of Monstera root rot, let’s delve into effective prevention strategies:

1. Proper Watering Techniques

  • Frequency of watering: To ensure proper watering, allow the soil to partially dry out before watering again. You can determine the moisture level of the soil by inserting your finger approximately an inch deep – if it feels dry, it indicates the need for watering. Overwatering should be avoided at all costs, as it can result in root rot.
  • Watering volume: Be sure to water well, as this allows water to reach the root zone. Make sure to remove any extra water that gathers in the saucer or pot.

2. Well-Draining Soil and Pot

  • Pot selection: Choose a pot with drainage holes to facilitate proper water drainage and prevent waterlogging. Opt for a size that accommodates the plant comfortably without occupying excessive space.
  • Potting mix: Use a well-draining potting mix that allows excess water to pass through, preventing water accumulation around the roots. Consider adding perlite or orchid bark to improve drainage.

3. Ideal Environmental Conditions

  • Sunlight: Monstera plants flourish in bright, indirect light. Position your plant close to a window or in a well-lit spot to ensure it receives the optimal amount of sunlight.
  • Temperature and humidity: Maintain a temperature range of 65-85°F (18-29°C) and humidity levels of around 60-70% to create an optimal growing environment for your Monstera.

If you spot fungus on your Monstera plant, acting promptly is crucial. First, scrutinize the affected parts to determine the extent of the fungal growth. To address the issue, carefully remove any infected leaves or plant sections using clean and sterilized pruning shears. Next, prepare a water and neem oil solution, following the recommended dilution ratio on the neem oil product. Apply the prepared mixture onto the affected areas of the Monstera, ensuring comprehensive coverage through spraying.

Additionally, enhance air circulation around the plant by providing sufficient spacing between neighboring plants or objects. Avoid overwatering and maintain proper drainage to prevent excessive moisture, which can contribute to fungal growth. Lastly, remain vigilant for any signs of recurring fungus and take immediate action if necessary. Regularly monitor your Monstera’s health and provide appropriate care to prevent and manage fungal issues.

Monstera Aerial Roots

Monstera Aerial Roots

Monstera plants possess captivating aerial roots that contribute to their unique charm. These roots naturally emerge from the stem or nodes of the plant, seeking support as they grow. Aerial roots are considered quite beneficial for Monstera plants. Apart from providing stability to the plant, these roots can absorb moisture and nutrients from the air around the plant. If you notice aerial roots on your Monstera, it is advisable to let them remain undisturbed. These aerial roots are significant for improving the overall well-being, health, and growth of the plant.

However, if the roots become excessive or unsightly, you can gently guide them back into the potting soil or provide support through a moss pole or trellis. Maintaining an appropriate humidity level around your Monstera is vital to ensure the health and vitality of the aerial roots. 


Should I re-pot my Monstera if it has root rot?

If the root rot is severe or the current potting medium retains excess moisture, repotting may be necessary. During the repotting process, use fresh soil, ensure adequate drainage, and handle the plant with care.

Signs of root rot in Monstera plants include yellowing or browning leaves, wilting, root discoloration, foul odor, and mushy or slimy roots upon inspection.

Can I save a Monstera plant with root rot?

If root rot is detected early, there’s a chance to save the Monstera plant. Remove affected roots, replant in well-draining soil, and adjust watering to prevent additional harm.

Can Monstera roots grow back after root rot?

If the damage is not severe and the underlying cause of root rot is resolved, Monstera roots can regrow. Enhancing drainage, modifying watering routines, and providing an appropriate environment encourage new root growth. Consistent monitoring and prompt care are vital for successful root regeneration and for preventing additional harm.

Can hydrogen peroxide treat root rot?

Using hydrogen peroxide as a remedy for root rot is possible, but it requires careful consideration. Proper dilution and application are crucial to avoid harm to the plant. Consultation with an expert is advised for specific guidance.
