How to Get Rid of Nematodes on Monstera Deliciosa Plant

Updated: July 2, 2023

Nematodes are tiny, thread-like worms that can wreak havoc on your beloved Monstera Deliciosa plant. These microscopic pests can cause significant damage to the roots, leading to stunted growth, wilting leaves, and even death of the plant if left untreated. Thankfully, there are several effective methods to get rid of nematodes and revive your Monstera Deliciosa’s health. In this article, we will explore these methods in detail.

Identifying Nematode Infestation

Before diving into the treatment options, it is crucial to identify whether your Monstera Deliciosa is indeed infested with nematodes. Some common symptoms of nematode infestation include:

  1. Stunted growth: If your Monstera Deliciosa is not growing as vigorously as it should be despite proper care, nematodes could be the culprit.
  2. Wilted leaves: Nematodes attack the roots, impairing the plant’s ability to absorb water and nutrients properly. This can result in wilting or yellowing leaves.
  3. Root damage: Carefully inspect the roots of your plant for any signs of decay or discoloration. Nematodes often cause root lesions and knots.

If you notice any of these symptoms, it is essential to take immediate action to save your Monstera Deliciosa from further damage.

Treatment Methods

1. Soil Sterilization

The first step in tackling nematode infestation is sterilizing the soil. This method eliminates not only nematodes but also other harmful organisms that may be present.


  1. Remove the Monstera Deliciosa from its pot and gently shake off excess soil from the roots.
  2. Prepare a mixture of one part bleach and nine parts water.
  3. Submerge the roots of the plant in the bleach solution for approximately 10 minutes.
  4. Rinse the roots thoroughly with clean water to remove any remaining bleach.
  5. Dispose of the contaminated soil, ensuring it does not come into contact with other plants or garden areas.
  6. Replace the soil with fresh, sterilized potting mix.

2. Solarization

Solarization is a natural method that uses sunlight and heat to kill nematodes and other soil-borne pests.


  1. Choose a sunny spot in your garden or balcony where you can place your Monstera Deliciosa pot.
  2. Remove the plant from its pot and loosen the soil around the roots.
  3. Water the soil thoroughly to ensure it is moist.
  4. Cover the pot with a clear plastic bag, making sure it is sealed tightly around the base to create a greenhouse effect.
  5. Leave the pot in direct sunlight for at least 4-6 weeks during the hottest period of the year.
  6. Monitor the plant regularly and ensure it receives adequate water during this period.
  7. After solarization, replace the soil with fresh, sterilized potting mix before repotting your Monstera Deliciosa.

3. Biological Control

Introducing beneficial nematodes or predatory insects can help control nematode populations naturally.


  1. Purchase beneficial nematodes from a reputable gardening store or online supplier.
  2. Follow the instructions provided to mix and distribute the nematodes in your Monstera Deliciosa’s potting mix.
  3. Beneficial nematodes attack and feed on harmful nematodes, effectively reducing their numbers over time.
  4. Alternatively, you can introduce predatory insects such as predatory mites or parasitic wasps, which also prey on nematodes.

4. Chemical Treatment

If all else fails, there are chemical treatments available specifically designed to target nematodes.


  1. Purchase a nematode-specific pesticide from a garden center or online supplier.
  2. Read and follow the instructions carefully, as these pesticides can be toxic if misused.
  3. Apply the pesticide to the soil as directed, ensuring all affected areas are treated.
  4. Monitor the plant closely for any adverse reactions, and discontinue use if necessary.

Preventive Measures

Prevention is always better than cure when it comes to nematodes. Here are some preventive measures to protect your Monstera Deliciosa from nematode infestations:

  1. Use sterilized potting mix: Always use fresh, sterilized potting mix when repotting your plant to minimize the risk of introducing nematodes.
  2. Practice proper hygiene: Wash your hands thoroughly before handling your plants to avoid transferring nematodes or other pests inadvertently.
  3. Avoid overwatering: Nematodes thrive in moist environments, so make sure not to overwater your Monstera Deliciosa.
  4. Rotate plant locations: If you have multiple plants, rotate their locations periodically to prevent nematode buildup in the soil.

By following these preventive measures and implementing the appropriate treatment methods, you can effectively get rid of nematodes on your Monstera Deliciosa plant and ensure its continued health and vitality. Remember that early detection and swift action are key in successfully combating nematode infestations.
