Vermicomposting: Complete Guide to Raising Composting Worms

Vermicomposting uses red worms to turn kitchen waste into premium castings — faster, cooler, and more nutrient-dense than traditional composting. Perfect for apartments and houses alike.

Bin Setup (3-Bin Stacked System)

1. 3 dark plastic bins, same size. One lid.
2. Drill ¼" holes in bottom of all bins (grid, 1" spacing).
3. Drill side holes 1" below rim (2" spacing) for ventilation.
4. Nest holed bin inside solid bin (catches tea).
5. 4" damp bedding: shredded paper, cardboard, leaves.

Feeding

• Fruit/veg peels, bread, coffee, tea, eggshells, pasta, leftovers.
• No meat, eggs, dairy, oils, excess citrus.
• Bury food; worms find it.
• Temp: 65–80°F. No direct sun.

Weekly Routine

• Check consumption. Add handful when prior food gone.
• Don't overfeed.
• Cover — worms need dark.
• Daily light misting.

Monthly Harvest & Bin Rotation

1. Prep new bin (holes, bedding, food).
2. Stack new atop old (bottoms touching bedding).
3. Worms migrate up through holes for food.
4. Remove old bin → harvest castings → wash → reuse next month.

Bonus Perks

• Kids love the biology (baby worms = science project).
• Free fishing bait.
• Minimal care, maximum output.

Happy vermicomposting!
