POTWORMS are among the tiny brown worms in houseplant soil, with an estimated 2500 of them in a square foot of soil. They are often an indication of soil-dwelling pests, which may not necessarily mean you are doing anything wrong.

Surprisingly, some may be beneficial to your indoor plants.

3 Common Tiny Brown Worms in Houseplant Soil

While there can be dozens of brown worms in houseplant soil, three are common, namely:

1. Fungus Gnats

These are small, flying insects that lay their eggs in moist soil. The larvae are tiny, brownish worms that feed on decaying organic matter and plant roots.

2. Potworms

Also known as soil mites, these are small, white, or brownish worms that feed on decomposing organic matter in the soil. They are generally harmless to plants.

3. Springtails

While not worms, springtails are tiny, jumping insects that can sometimes be mistaken for small worms. These, feed on decaying plant matter and fungi.

Why Are There Tiny Brown Worms in Houseplant Soil?

As mentioned earlier, you shouldn’t panic for you haven’t done anything wrong. These organisms are common in soil and, in most cases, are not harmful to plants.

However, you might want to be more vigilant as the following section shows in part, your contribution.

Decomposition

Earlier, I pointed out that potworms feed on decaying organic matter in the soil.

If you’re using organic materials like compost, bark, or other organic amendments in your potting mix, these worms might be present to help break down the organic matter.

Moisture

Brown worms, especially potworms thrive in moist conditions. Overwatering your plants can create a suitable environment for these worms.

Ensure that you allow the top layer of soil to dry out between waterings to discourage their proliferation.

Overfeeding

If you’re providing excessive amounts of fertilizer to your plants, it can lead to an abundance of organic matter in the soil, attracting potworms.

Use fertilizers sparingly and according to the recommended guidelines for your specific plant.

How to Get Rid of Tiny Brown Worms in Houseplant Soil

Here are some effective methods, to get rid of tiny brown worms in houseplant soil, or the steps to manage their population:

Allow the Soil to Dry Out

Because potworms thrive in moist conditions, allowing the top layer of soil to dry out between waterings can help discourage their presence.

NB. Be sure not to overwater your plants.

Improve Soil Drainage

Ensure that your plant’s pot has proper drainage to prevent waterlogged conditions, which can create an environment favorable to potworms.

Repotting your plant with well-draining soil is the easiest way to solve the problem.

Stir the Soil Surface

Gently stir the top layer of soil with a stick or fork. This can expose the potworms to air and sunlight, creating an inhospitable environment for them.

By repeating this process periodically, you will not only get rid of potworms but also several harmful insects.

Adjust Feeding Habits

If you’re using a lot of organic amendments or compost, consider reducing the amount to discourage potworms.

Introduce Beneficial Organisms

You can introduce beneficial predatory mites or nematodes to the soil. These natural predators feed on potworms and can help control their population.

When using this method, be sure to follow the recommended guidelines for the specific beneficial organisms you choose.

Use Diatomaceous Earth

Permaguard Fresh Water Food Grade (pictured ⬆) is a natural powder you can sprinkle on the soil surface. The product contains tiny, sharp particles that can be effective against various pests, including potworms.

Regarding this product, here is a sneak view of what others are saying about it:

Neem Oil

Neem oil is another natural insecticide, effective against various pests, including soil-dwelling organisms.

Dilute neem oil according to the instructions and apply it to the soil. However, be cautious with neem oil, as it can affect beneficial insects as well.

Repot with Fresh Soil

If the infestation persists, repot your plant with fresh, well-draining soil. Remove as much of the old soil as possible without damaging the plant’s roots.

Pro tip

Avoid using chemical pesticides unless absolutely necessary, as they can have negative effects on beneficial organisms and may not be necessary for controlling potworms.

Always follow the instructions on any product you choose to use.
