Set up a worm bin to transform kitchen scraps — vegetable peels, coffee grounds, eggshells — into rich, dark compost that supercharges the soil in your garden.

The Essentials

Steps

  • Get a bin with a lid and drill small air holes in the sides and lid.
  • Add moist, shredded bedding like newspaper or cardboard, then a handful of soil.
  • Add red wiggler worms — the species best suited for composting food scraps.
  • Bury small amounts of fruit and vegetable scraps under the bedding, avoiding meat, dairy, and citrus.
  • Keep the bin in a shaded, temperature-stable spot and check moisture weekly, misting if it feels dry.

Tips

  • Chop scraps into small pieces so worms break them down faster.
  • Harvest the dark, crumbly compost every few months by pushing everything to one side and adding fresh bedding to the other.
  • A healthy bin should smell earthy, not rotten — a bad smell usually means too much food or too much moisture.
  • Worms multiply on their own, so one starter batch can grow into a self-sustaining colony.
