Worms live in my kitchen:
If you don’t have an outdoor space, or would like to compost all winter long, an indoor compost bin is the way to go. A time-tested approach to indoor compost is a vermiculture system (AKA worm bin).
First, a little bit about worms:
- vegetable trimmings (i.e. carrot ends, celery tops, knobby lettuce ends, etc)
- apple cores
- crushed egg shells (rinsed out)
- tea leaves and tea bags
- coffee grounds and filters*
- potato peels
- vegetables that have been in the fridge too long and gone bad
- citrus fruits (i.e. lemons, grapefruit, orange)
- spicy and/or waxy vegetables like green pepper, jalapenos, etc.
- meat, bones, fish
- dairy products
- pet waste
- excessive amounts of coffee grounds are not healthy. Use in moderation!
- Some of these items are ideal for an outdoor compost bin, but we are slightly more delicate!
Recipe for a perfect indoor compost bin:
- One plastic tub with lid (rinsed with soap and water) Note: size is approx. 4 sq. ft in size, NO MORE than 10-16 inches deep
- Drill with ¼” bit
- ½ to 1 lb. red wigglers (Eisenia fetida, available at wormwoman.com)
- Handful of soil
- Newspaper (No glossy ad pages)
- Spray bottle of water
- Food waste* (See above “what we eat”)
- Drill holes in the lid of your bin. The more the merrier
- Shred newspaper into 1/4 to 1/2“ strips and lay on the bottom of the bin to form a bedding layer.
- Spray the paper with water until damp. The paper should only be as wet as a wrung out sponge and there should not be any liquid on the bottom of the bin.
- Add worms and handful of soil
- Add a small amount of food waste*
- Cover worms and food with another layer of newspaper
- Store in a cool, dark place and make sure that the bin will not be exposed to freezing temperatures
- Feed worms no more than 1 lb. food waste, per day, per 1 lb. worms, making sure that there is always a layer of damp newspaper covering food and worms (keeps flies away).
