- Dry Bedding Material
(use a combination of one or more dry bedding ingredients listed below)
- Brown leaves/straw
- Shredded paper or newsprint (avoid glossy paper)
- Egg cartons /coffee trays
- 2 Tablespoons - crushed eggshells or agricultural lime
- 1 litre of soil (ordinary garden soil)
Steps to Prepare Bedding
- Fill worm bin with dry bedding material. (leaves, shredded paper, etc.)
- Add water (approximately 2-3 litres) and mix contents.
- Bedding should be the consistency of a wet sponge.
- Pour off any excess water. (Worm bin should be ½ full of wet material)
- Add more dry bedding or water as required.
- Add crushed eggshells/limestone and soil.
- Add the worms.
Adding the Worms to the bin
To ensure your worm bin is fully ventilated, drill at least 10-20
- 3/16" holes in your bin.
Water should be left out overnight prior to preparing bedding.
This will insure any chlorine evaporates and will bring water to room temperature.
Do not use water from a water softener - the salt will burn your worms.
Important: Be sure to add the worms to the composter under direct light.
Simply place the worms on top of bedding. Their natural photophobic
tendencies will force the worms into the bedding to a darker, more comfortable
environment. Allow the worms to settle into bedding for a few days before
feeding for the first time.
As most worm bins have air holes in the bottom, the worm bin should
be raised off the ground. A tray should also be placed under the worm
bin to catch any excess liquid. If liquid is dripping out of the bottom,
this is an indication the worm bin is too wet. Simply pull back bin
contents, and add dry bedding on the bottom to absorb the excess liquid.
Feeding the Worms
As the worms do not like to be disturbed, it is best to feed the worms
1-2 times per week rather than daily. Worms eat about half their weight
daily. If feeding twice a week, add 1.5 - 2 lbs. each time. If a lot
of food scraps are left over from previous feeding wait a day or two
prior to adding additional food.
Bury food a couple of inches under the bedding. Bury the food in a different location each time. Be sure to cover food with bedding. Fruit flies are attracted to exposed food. Sprinkle a handful or so of crushed eggshells on top of bedding about once a week. Eggshells counter the acidity in food scraps. Do not over feed the worms!
Add additional bedding (eg. leaves, straw, shredded paper, etc.) when it is difficult to bury food scraps. Also helps absorb excess moisture if bedding becomes too wet. Worms generate heat and produce liquid, therefore, condensation will form on the lid.

Worms do not have teeth, they have a gizzard and use the soil to process their food. Your worms will be eternally grateful if you chop the organic material into small pieces. The smaller the pieces, the greater the surface area to rot. The worms can process the organic matter more rapidly. They adore the pulp from juicers.
Do not include: meat & dairy products or pet waste.
Location of Bin
Store worm bin in cool, preferably dark place. Worms can live in 5° C - 30° C (40° - 90° F) temperature, ideal temperature 15° C - 21° C (60° - 70°F).
Do not allow worm bin to freeze.
Harvest the worms when bedding has almost all been consumed (or turned
into beautiful black castings) (4-6 months). Do not feed the worms for
one-two weeks prior to harvesting. Allow the worms to finish their job.
If any bedding or organic material is remaining, simply set aside and
add with new bedding. There are several methods for harvesting.
Dump and Sort
Under bright lighting, empty composter contents onto a plastic sheet.
Separate into pyramid shaped piles. Wait 10-15 minutes. Worms are very
photosensitive, so to avoid the light, the worms will crawl to the bottom
of the piles. Remove the top portion of each pile. Repeat this process
until only the worms are remaining. Add the worms to fresh bedding and
start vermicomposting process over again. Mix nutrient rich castings
in gardens and houseplants.
Side to Side (If you are not comfortable handling
the worms you may want to try this method of harvest.)
Feed the worms on one side of the bin for a number of weeks. This will
force the worms to migrate to that side of the bin. Once the worms have
moved over to the food source, remove the castings from the vacated
quadrant. Replace the castings with fresh bedding (see bedding preparation
above). Wait a week or two then repeat the process in the opposite direction,
herding the worms into the new bedding.
