Quick Answer: Do Worms Poop?

In short, yes, they do. But what impact does this have on your compost pile? Worms are an essential part of any healthy ecosystem. They help aerate the soil and break down organic matter so it can be easily composted into nutrient-rich compost that you can use for your fruits, veggies, and plants. However, not many gardeners know whether worms poop or not.

Healthy soil, believe it or not, is made by earthworms.

They dig through the earth and ingest different compounds, and their tunnels ensure soil aeration.

Worms consume dirt, manure, and other organic matter, including dead roots, leaves, and grass.

Their digestive system then turns all of these into what is known as humus. This humus contains all the nutrients required for healthy plants.

In other words, worm poop is vital to a healthy garden. The mysterious aspect is that this worm poop is a more concentrated form of the nutrients they ingest.

The surrounding soil contains less potassium, nitrogen, phosphorus, and calcium than the worm poop.

All About Worm Poop

In only one year and on one acre of land, earthworms can move eight tons of dirt and excrete enough worm poop to make two feet of fresh, nutrient-rich soil, according to Charles Darwin.

This was also discussed by several researchers in an article published by The New York Public Library.

As a result, it is not surprising that many people go to certain lengths to attract earthworms to their garden.

There is no better help with soil than them! As a result, it is important to ensure that the garden is mulched and well-watered since worms are attracted by damp and cool environments.

They are sensitive to extreme weather, so a cover crop can be placed during the winter to ensure that worms survive until spring.

Acidic soil is also a deterrent to worms, so you should test and ensure that your soil’s pH is above 4.5 if you want to ensure a healthy population of worms.

Furthermore, as you test the pH, it might be wise to test the nutrients, too.

Worms love calcium, so you should check whether you need to supplement the calcium levels. Finally, worms love well-maintained gardens with lots of organic matter.

This can be shredded leaves, grass clippings, and compost.

Worms are quite sensitive, so rototillers and shovels will cause them damage. It is best to use a broadfork or a flat-tined fork to turn the soil.

They love organic and natural areas, so they will leave your garden if you use any synthetic pesticides and fertilizers.

People who create their own compost naturally attract worms, too. You can grow your own worms and make your own compost in no time.

You can build a compost heap made of fruit and veggie scraps, which will attract worms. Worms will turn your pile into compost, and then you can use the compost to feed the earthworms in your garden.


All in all, worms have an excretion system that releases castings with the consistency of clay.

These tiny invertebrates are absolutely vital to your garden, as their castings help provide all the necessary nutrients for your plants, ensuring plant development and health.
