A few months ago, I placed a few red wiggler worms in my outdoor trash can compost bin to see what they would do.
It ends up they multiplied and they’re eating through my food scraps nicely!
Composting worms make a great addition to compost bins smaller than 1 cubic yard. Technically, they work with any size system, but the worms will make more of a noticeable difference with smaller systems since they take longer to process organic material.
Two issues with small-scale compost bins include that they don’t get as hot, and the contents don’t break down as fast- adding worms will greatly help with both.
