What to Feed Your Composting Worms (And What to Avoid)

A worm bin turns kitchen scraps into premium fertilizer—but only if you feed them right. Drill ventilation holes, add damp newspaper bedding, then introduce red wigglers.

Worm Favorites

• Coffee grounds (filters included)
• Fruit peels (soft, moist = fast breakdown)
• Bread (soaked = instant soft food)

Avoid These

• Citrus, onion, potato peels (worms ignore them)
• Meat, dairy, oily foods (rot, smell, attract pests)
• Pet waste, glossy paper, treated wood

Pro Tips

Chop large scraps. Bury food under bedding to deter flies. Keep bin moist, not wet. Harvest castings in 2–3 months.

Feed them well, and they’ll feed your garden beautifully.
