Wormery Basics

  • Use Eisenia species (tiger worms). Keep between 10–25 °C.
  • Feed small amounts: veg peels, coffee grounds, tea leaves, crushed eggshells.
  • Avoid lots of citrus, onion skins, meat/dairy/oils.
  • Cover scraps with cardboard or coir; keep just moist.

Simple Stack System

  1. Start with a base tray and bedding (moist coir/cardboard).
  2. Add worms; feed lightly for the first 1–2 weeks.
  3. When the tray fills, add a second tray on top — worms move upward.
  4. Harvest castings from the bottom tray; dilute leachate 1:10 for feed.

No smell rule: if it smells, you fed too much or it’s too wet. Add dry cardboard and pause feeding.

Balcony-Friendly Composting

  • Small tumblers work if secured from wind.
  • Bokashi pre-composts kitchen waste for later mixing into soil (use outdoors to finish).
  • Use finished compost to top-dress containers mid-season.
