Shredded cardboard and paper in a Worm Factory tray

Cardboard is a great bedding and addition to your compost bin. It adds a carbon-rich “brown” component, and worms love to eat it. The texture of the cardboard provides a rich microbial environment for the worms, as well as properties that hold moisture and promote airflow in the bedding. The worms may even get nutrition from the glues in corregated cardboard.

Cardboard can be added in sheets, but if it is torn up or shredded they’ll break it down faster. Added to the top of a tray or bin, it can keep in moisture, prevent odors from developing, and keep the fruit flies away.
