Earthworms are vital to the garden ecosystem. We talked to a horticulturalist about how to attract them to your garden and how to keep them happy.

Worms have been born in a Mars soil simulant for the first time, bringing the prospect of farming on the Red Planet a step closer to reality.

The digging and tunneling aerates and loosens the soil profile, allowing oxygen in. Worms can eat their weight each day. Earthworm life span varies from species to species.

Other, unpigmented earthworms eat soil and make horizontal burrows close to the soil surface. These include the gray worm (Aporrectodea caliginosa).

Besides adding nutrients to the soil, earthworms also keep the soil healthy by tunneling. As they eat, earthworms create tunnels that keep the soil open and full of paths for water and air.

In what could be an important milestone for future farmers on Mars, two healthy baby worms were recently born in simulated Martian soil.

But so one of the most interesting findings from our work has been that, yes, the earthworms take those leaves and they mix some of it in with the soil, but they also eat a lot of those leaves and ...
