Why it Can be Good To Put Earthworms in Potted Plants
To understand why earthworms can be good for your potted plants, you must realize that earthworms and plants have lived together and evolved for over more than 100 million years. Since then they have adapted to each other in a way that is beneficial for both.
Earthworms will not eat roots or other living animals but will only ingest organic matter that has microorganisms on it and digest these organisms to survive and live.
After digestion of this particular organic matter, the earthworms will poop out the rest of the organic matter which will be rich in nitrogen, minerals, and enzymes. The castings of the earthworms will improve the quality of the soil.

Another reason why earthworms can be beneficial for plants is that they aerate the soil. Because they make tunnels in the soil, the soil will be richer in oxygen, water, and the soil will be mixed. Also because of the tunnels in the soil, the plant roots can grow easier through the soil.
Also, if there is somehow no organic matter in your plants' soil, earthworms will be still able to survive. Plants excrete sugars from their roots into the soil to feed the bacteria that help the plant make nutrients. These bacteria are the ones that earthworms love to eat and that is why they will never starve around a plant.
Earthworms placed in potted plants generally benefit the soil and the plant as long as there is the presence of decaying materials that the worms can eat. But there can also be disadvantages of adding worms to your potted plants, explained below.
What are the Cons of Adding Earthworms in Potted Plants?
Regardless of what type of worm you want to put in your potted plant, their castings will always benefit the soil. Thus, it also gives positive effects on the plants within that soil. However, adding earthworms to your houseplants pots can become messy when you don't know what you are doing.
These are the cons of adding earthworms in potted plants:
- Some kinds of worms can reproduce fast which can lead to overpopulation (and them crawling out of the pot).
- When you let the soil dry out completely, the worms will die or escape the pot.
Earthworms are hermaphrodites, which means they have both male and female sex organs. Despite still needing to trade sperm cells in order to reproduce, some kinds of earthworms can reproduce really fast.

The kind of earthworm you don't want in your plants' pot is the Red Wiggler. This kind of worm will reproduce at a very fast paste which means that your plants' pot can be full of worms in no time. If the pot becomes overcrowded, the worms can leave the pot, looking for food. You might also find them in the bottom of the pot crawling out of the drainage holes, looking for nutrients.
Earthworms like to live and breed at a certain amount of temperatures and moisture in the soil. Outdoors, they adjust themselves by digging to the deeper or more shallow ground to suit their needs.
An average houseplant pot is not big enough for an earthworm to adjust itself to the amount of moisture that it needs. When the soil starts to dry out the soil will be too dry for the earthworms in the pot and the earthworms might die or climb out of the pot. When this frequently happens, all the earthworms will die. Besides that, too many dead worms in your soil won't exactly smell nice.
Many people claim that earthworms may start feeding on roots once there is no organic matter or bacteria in the pot to consume anymore. This is actually not true, earthworms will only eat the roots if they are already dead and rotting underneath the soil.
The worms that feed on live roots are called nematodes and Grub worms (Japanese Beetle larvae).
