Imagine this: if everyone in the US vermicomposted their kitchen scraps for one year, the amount of diverted waste could cover the city of San Francisco with a 3 ft deep layer of compost! It’s time we start employing some of our subterranean friends. Use a worm bin – they’re cheap, odorless, and small enough to fit underneath your kitchen sink – to easily turn food waste into nutrient-rich fertilizer for your outdoor or indoor plants.
For best results, keep your wriggling waste consumers happy by feeding them properly
- 15-20 gallon ecology center worm bin or set of bin-making materials
- Shredded newspaper
- 1lb of worms / sq foot
- Chopped compostable materials
- Drill ½” holes into the bottom and sides of your bin for ventilation and drainage.
- Add at least 2 inches of shredded newspaper and cardboard for bedding.
- Moisten until damp, not soaked.
- Add 1 lb of worms/ sq foot.
- Feed your worms! Add chopped compostable materials once a week or daily. Add 2 to 3 inches of bedding each time to hide any food scraps.
- Harvest the vermicast (worm poop=black gold) every 3-6 months. Mix vermicast into potting soil or use alone as fertilizer.
- Fruit scraps and peels (citrus in moderation)
- Veggie scraps (root vegetables should be chopped to avoid sprouting.)
- Tea bags
- Coffee grounds and filters
- Pizza crust and popcorn
- Non-greasy leftovers
- Bread and grain
- Paper towels and tissues
Not worm food:
- Whole corn cobs
- Meat, fish, dairy products (may attract rodents)
- Buttery, greasy, or oily foods
- Pet waste
