Food for a home worm bin:
Fruit and vegetable scraps are always a safe bet .
Collecting kitchen scraps in small lidded bucket allows them to age for a while
before adding them to the bin. Aging encourages microbial colonization while
the food is breaking down. This will happen in the worm bin actually but the
worms won't start feeding on the materials until they are starting to rot.
You can also add tea bags and coffee grounds with filters to your bin. Be moderate with this material as it can be very acidic. Worms love orange veggies! Pumpkins, butternut, as well as any variety of melons.
These materials will break down into liquid so watch that your material doesn’t get too wet for the worms. Too much water robs the bedding of air.
Foods to avoid: dairy; meat; onions, citrus fruits and garlic.
