Similarly, do worms hurt plants?
Regardless of worm type, their castings -- the product left after worms digest food -- benefit soil and therefore the plants within the soil. However, earthworms in pots may damage root systems, particularly of young plants.
Subsequently, question is, will worms eat my plants? As you've already learned, earthworms help provide soil with lots of great nutrients. A plant's roots are the parts that allow a plant to use the nutrients that the worms provide. Roots help plants grow, and then earthworms eat the leftover parts of plants and the cycle starts all over again!
Also know, how do I get rid of worms in my potted plants?
Harmful pests such as cutworms and leafminer larvae should be submerged in warm, soapy water to kill them so they don't harm other plants. There are a range of insecticidal soaps that are effective at killing pests. Use a ready-to-use insecticidal soap and spray the worms, repeating the application as needed.
Do worms mean good soil?
Worms help to increase the amount of air and water that gets into the soil. They break down organic matter, like leaves and grass into things that plants can use. Having worms around in your garden is a real good sign that you have a healthy soil.
