How to Get Rid of Nematodes on Fernwood Snake Plant

Updated: May 6, 2022

Fernwood snake plants are popular houseplants that are easy to care for and can thrive in a variety of environments. However, one of the challenges that many growers face is dealing with nematodes.

Nematodes are tiny, worm-like organisms that can infest the soil of your fernwood snake plant. They feed on the roots of the plant, which can cause stunted growth, yellowing leaves, and even plant death if left untreated.

In this article, we will discuss how to identify nematode infestations, how to get rid of them, and how to prevent them from coming back.

Identifying Nematode Infestations

The first step in dealing with nematodes is to identify whether or not your fernwood snake plant is infested. Here are some signs to look out for:

  • Stunted growth: If your fernwood snake plant is not growing as quickly as it should be or if it looks smaller than it did before, this could be a sign of nematode damage.
  • Yellowing leaves: Nematodes can cause the leaves of your fernwood snake plant to turn yellow or brown.
  • Wilting: If your plant appears to be wilting or drooping, this could be a sign that the roots have been damaged by nematodes.

If you notice any of these signs, it’s important to act quickly to prevent further damage.

Getting Rid of Nematodes

There are several methods that you can use to get rid of nematodes on your fernwood snake plant:

1. Soil Solarization

Soil solarization involves covering the soil around your fernwood snake plant with clear plastic and leaving it in direct sunlight for several weeks. This method works by heating up the soil and killing off nematodes and other pests.

To use this method, you will need to remove your fernwood snake plant from its pot and place it in a temporary container. Cover the soil around the plant with clear plastic and leave it in direct sunlight for at least 4-6 weeks.

2. Neem Oil

Neem oil is a natural pesticide that can be used to kill nematodes on your fernwood snake plant. To use this method, mix 1-2 tablespoons of neem oil with 1 quart of water and spray the solution onto the soil around your plant.

Repeat this process every 7-10 days until the nematode infestation has been eliminated.

3. Beneficial Nematodes

Beneficial nematodes are a type of microscopic worm that can be used to kill off harmful nematodes in the soil. They work by entering the bodies of harmful nematodes and releasing bacteria that kill them off.

To use this method, purchase beneficial nematodes from a garden center or online retailer and mix them into the soil around your fernwood snake plant according to the instructions on the package.

Preventing Nematode Infestations

Preventing nematode infestations is key to keeping your fernwood snake plant healthy. Here are some tips to help you prevent nematode infestations:

  • Use sterilized potting soil: Make sure that the soil you use for your fernwood snake plant is sterilized to prevent pests from entering.
  • Keep your plant healthy: A healthy fernwood snake plant is less likely to attract pests like nematodes. Make sure that you are providing your plant with adequate water, light, and nutrients.
  • Avoid overwatering: Overwatering can create conditions that are favorable for nematode growth. Make sure that you are not watering your fernwood snake plant too frequently.
  • Rotate plants: If you have multiple fernwood snake plants, rotate them every 6 months to prevent nematodes from becoming established in the soil.


Are nematodes harmful to humans?

No, nematodes are not harmful to humans. They only feed on plant roots and do not pose a threat to human health.

Can I reuse soil that has had a nematode infestation?

It is not recommended to reuse soil that has had a nematode infestation. Instead, replace the soil with fresh, sterilized potting soil.

How long does it take for neem oil to kill nematodes?

Neem oil can take several weeks to kill nematodes. Repeat applications every 7-10 days until the infestation has been eliminated.
