DIY Magic: Building Your Own Worm Farm

What Materials do You Need to Build a Worm Farm?

  1. Two plastic bins (dark colored, not transparent) – one bin should be able to fit inside the other with some space left at the bottom.
  2. A drill (ask an adult for help).
  3. Newspaper or cardboard.
  4. Soil.
  5. Worms (red wiggler worms are the best).
  6. Kitchen scraps (like vegetable and fruit peels).

Folklow This Step-by-Step Guide to Build Your Own Worm Farm:

Step 1: Prepare the Bins

  • Take the two plastic bins. The bottom bin will catch any liquid that drains (this is called “worm tea” and is great for your plants!).
  • Drill about 8-10 small holes in the bottom of the top bin. These are for drainage and air.
  • Also, drill some holes on the sides near the top for more air.

Step 2: Bedding for the Worms

  • Tear up some newspaper or cardboard into small pieces. This will be the bed for your worms.
  • Wet the torn newspaper or cardboard so it’s damp but not too soggy.
  • Put this damp bedding in the top bin until it’s about halfway full.

Step 3: Adding Soil and Worms

Step 4: Feeding Your Worms

  • Worms love kitchen scraps! Add some vegetable and fruit peels, but avoid meat and dairy products.
  • Bury the scraps under the bedding so it doesn’t attract flies.
  • Don’t overfeed your worms. Start with a small amount and see how quickly they eat it.

Step 5: Cover and Check

  • Cover the bin with a lid (remember, it should have air holes).
  • Place your worm farm in a cool, shaded area.
  • Check on your worms every few days to make sure they’re happy. The bedding should always be damp, and the worms should be eating the scraps.

Step 6: Harvesting Your Compost

  • After a few months, you’ll see less bedding and more compost (worm poop). This is great for your plants!
  • To harvest, move the compost to one side of the bin and add new bedding and food to the other side. The worms will move to the new bedding, and you can take out the compost.


  • Worms are living creatures, so take good care of them.
  • If the bin smells bad or the worms aren’t eating, something might be wrong. Check if the bedding is too wet or if there’s too much food.
