Build a Mini Wormery (Meet the Real Wiggle Worms!) 🐛

Children building a mini wormery

Earthworms are the most important workers in any Irish garden. They eat dead leaves and turn them into incredible, nutrient-rich soil. To show kids exactly how hard these little guys work underground, we are going to build a see-through mini wormery!

What You Need:

  • An empty, clear 2-litre plastic bottle (top cut off by an adult)
  • Sand
  • Damp garden soil
  • A handful of dead leaves or veggie peels
  • Black paper or a dark towel
  • The Stars of the Show: 3 or 4 earthworms carefully dug up from the garden!

Building the Worm Hotel:

  1. Layer it Up: Start filling the plastic bottle with alternating layers of damp soil and sand. Make each layer about 2 inches thick. The contrasting colours will help you see the worms at work!
  2. Add the Roof: Leave a couple of inches of space at the top. Add a layer of dead leaves, old lettuce, or potato peels. This is the worms' dinner.
  3. Welcome the Guests: Gently drop your worms onto the top layer. Watch as they quickly burrow down into the dark to hide.
  4. Keep it Dark: Worms hate the light! Wrap the outside of the bottle in black paper or an old towel so it is pitch black inside. Leave it in a cool, quiet place indoors.

👀 The Big Reveal!

After a few days, unwrap the black paper. You will see that the worms have mixed all the neat layers of sand and soil together, creating tunnels right against the plastic! Important: After a week of observing, be sure to release your worms back into the garden where they belong.
