Worm Compost Bin: Turn Kitchen Scraps into Garden Gold

Stop throwing out garbage—coffee grounds and banana peels become powerful plant supplements when digested by worms into castings. A worm bin provides a steady supply for flowers and vegetables.

Building the Bin

• Use a plastic/rubber storage bin. Drill air holes; cover with window screen to keep fruit flies out.
• Optional: add a hose spigot near bottom for “worm tea” (even better than compost tea). Mix 1–2 cups in a watering can, fill with water, use normally.

Bedding and Grit

• Shredded newspaper is ideal bedding—keep moist but not soggy (spray bottle). Avoid peat moss (non-renewable) unless you prefer it.
• Add garden soil, rock dust, or powdered limestone for grit—worms lack teeth.

Worms

Don’t use earthworms; they need soil. Buy red wigglers—they thrive in bins. Ratio: 2 lbs worms per 1 lb daily garbage. For 0.5 lb daily waste, start with 1 lb worms.

Maintenance

• Check daily initially. Keep bedding moist; bin at 60–70°F. Summer sun cooks worms.
• If bin smells, add more bedding.

Fun family project—kids love watching worms. Great for your garden too!
