Worm Composting

Worm composting (or Vermicomposting) recruits red wiggler worms to convert our non-meat food scraps into nutrient-rich compost that can be used to improve the health of our yards, gardens and houseplants. See detailed information on how to start composting with worms (pdf).

What to Feed Your Red Wiggler Worms

In general, Red Wiggler Worms will consume fruits and vegetable scraps as well as the items in the list below.  
  • Fruit, left over vegetable scraps and peelings
  • Coffee grounds, tea leaves and tea bags
  • Vacuum cleaner dust
  • Hair clippings (people and animals)
  • Manures (well aged)
  • Shredded paper such as newspaper and office paper (soak first)
  • Crushed egg shells.

The greater the variety of material used, the better the casting (compost) will be.
