A worm bin can be a great way to make a great soil ammendment for your garden, keep a year round supply of free worms, and get rid of your organic waste while preventing it from going to the landfill.

To Make a worm bin, you will need the following things:

  1. Rubermaid Bin
  2. Coconut coir, Peat Moss or Shredded Cardboard/Paper
  3. Food Scraps
  4. Drill
  5. Worms
  6. Spray bottle

Worm Bin


Steps

  1. Drill holes into your bin. 1/8″ holes seem to work the best. Drill some holes on the side of the bin and on the lid. Anywhere from 10-20 holes should be enough.
  2. Drill 4-5 holes on the bottom of the bin for drainage.
  3. Fill your bin halfway full with the bedding material you choose. Coconut coir, peat moss, composted manure, or shedded cardboard/paper all make for good choices. Dirt or Potting soild do not make good bedding for these types of worms.
  4. Add moisture to the bin by spraying it with a squirt bottle, or just slowly pouring some water in. Be careful not to add too much water. There should not be puddles at the bottom of your bin. It should be moist, but not wet.
  5. Add in the foodscraps. Fruit and veggie wastes are great food for the worms but they can eat just about anything organic including bad leftovers. Try to avoid meat, dairy, and greasy foods as they could attract other unwanted guests.
  6. Add another layer of bedding on top. This will prevent flies from getting to your food scraps.
  7. Add the worms!

Tips

  • Make the bin a few days before the worms will arrive and add a handful of dirt from your yard. The soil will provide good bacteria and microbes to start breaking down the food. Preparing it early allows for the material to start decomposition, softening it up for your worms to eat.
  • Keep a light on over the bin for a few days after introduction into the bin. The worms will not be used to your new bin and may try to climb out if you don’t keep a light on.
  • Worms can eat half their weight a day in organic matter. So if you produce 2 lbs. of waste per day, you would need 4 lbs. of worms and a bin with approx. 4 sq. feet of surface area would work well.
