How to Avoid and Fix Stem Rot on Monstera?


Monstera plants, with their large and vibrant leaves, are a popular choice among gardeners and plant enthusiasts.

However, one common issue that can arise when caring for Monstera plants is stem rot.

Stem rot is a fungal disease that affects the stems of the plant, causing them to become soft, mushy, and eventually collapse.

In this article, we will explore how to avoid and fix stem rot on Monstera plants, ensuring that your plants stay healthy and thriving.

What Causes Stem Rot on Monstera?

Stem rot is primarily caused by overwatering and poor drainage. When the soil around the Monstera plant remains consistently wet, it creates the perfect environment for fungal growth.

The excess moisture leads to the development of fungi, such as Pythium or Phytophthora, which attack the stems of the plant, causing them to rot.

Signs of Stem Rot

To effectively treat stem rot, it is important to recognize the early signs of the disease. Here are some common symptoms to look out for:

  • Soft and mushy stems: The stems of the Monstera plant will feel soft and mushy to the touch. They may also appear discolored or have a foul odor.
  • Wilting leaves: The leaves of the plant may start to wilt and droop, even if the soil is moist.
  • Yellowing leaves: The leaves may turn yellow or brown, indicating that the plant is not receiving enough nutrients due to the rotting stems.
  • Stunted growth: The plant may stop growing or show signs of stunted growth.

How to Avoid Stem Rot on Monstera

Prevention is key when it comes to avoiding stem rot on Monstera plants. By following these tips, you can create an environment that discourages fungal growth and keeps your plants healthy:

  • Proper watering: Avoid overwatering your Monstera plant. Allow the top inch of soil to dry out before watering again. Ensure that the pot has drainage holes to allow excess water to escape.
  • Well-draining soil: Use a well-draining potting mix that allows water to flow freely through the soil. Avoid heavy soils that retain moisture for extended periods.
  • Adequate sunlight: Monstera plants thrive in bright, indirect sunlight. Ensure that your plant is placed in a location that receives enough light to promote healthy growth.
  • Good air circulation: Proper air circulation helps prevent the buildup of moisture around the plant. Avoid placing your Monstera plant in a stagnant or poorly ventilated area.
  • Regular inspections: Regularly inspect your Monstera plant for any signs of stem rot or other diseases. Catching the issue early can help prevent it from spreading and causing further damage.

How to Fix Stem Rot on Monstera

If you notice signs of stem rot on your Monstera plant, it is important to take immediate action to prevent further damage. Here are the steps to fix stem rot:

  • Remove affected stems: Carefully remove any stems that show signs of rot. Use clean and sterilized pruning shears to make clean cuts just above the healthy tissue.
  • Treat with fungicide: Apply a fungicide to the remaining healthy stems and the soil to eliminate any remaining fungal spores. Follow the instructions on the fungicide label for proper application.
  • Adjust watering habits: Allow the soil to dry out more between waterings to prevent further fungal growth. Ensure that the pot has proper drainage to avoid waterlogged conditions.
  • Improve air circulation: Increase air circulation around the plant by placing it in a well-ventilated area or using a fan to promote airflow.
  • Monitor and maintain: Regularly monitor your Monstera plant for any signs of recurring stem rot. Adjust your watering and care routine as needed to prevent future issues.

By following these steps, you can effectively treat stem rot on your Monstera plant and restore its health.

Will Underwatering Cause Stem Rot in Monstera Plants?

Underwatering can potentially lead to stem rot in Monstera plants, compromising their houseplants and water survival. Adequate watering is crucial for these tropical plants, as it helps maintain their overall health and prevents stem rot from occurring. Regularly monitoring soil moisture and ensuring proper hydration is essential in supporting the thriving growth of Monstera plants.


Stem rot can be a frustrating issue to deal with when caring for Monstera plants.
