How to Make and Use Vermicompost for a Thriving Vegetable Garden

Vermicompost—worm-digested organic matter—delivers water-soluble nutrients and beneficial bacteria as nature's perfect organic fertilizer. Here's how to produce and apply it.

Choosing Your Worms

• Temperate regions: Eisenia fetida (red wigglers)—industry standard
• Tropical regions: Perionyx excavatus (blue worms)
• Acidic soils: Eisenia hortensis (European nightcrawlers)

DIY Vermicompost Bin

1. Large plastic/rubber tote with lid
2. Drill ventilation holes (lid, sides) and drainage holes (bottom)
3. Layer: 2" shredded newspaper → shredded leaves/grass (limited) → food scraps → 2" newspaper
4. Add worms on top; they'll migrate down to food
5. Keep moist (daily misting); place tray underneath for drainage
6. Recycle leachate back into bin

Harvesting Methods

Method 1 (Dump & Sort): Empty bin, manually separate worms from castings.

Method 2 (Side Migration): Initially feed only one half. When harvesting, feed opposite half. Worms migrate to food, leaving clean castings behind.

Applications

• Mix directly into garden soil
• Brew into compost tea for foliar/root feeding
• Top-dress around established plants
• Seed-starting mix amendment

Vermicomposting works year-round, indoors or out. Free fertilizer from waste—what's not to love?
