Home Composting in 10 easy steps

At first glance, composting may seem complicated but once you’ve read this article, you’ll see how easy the process is, whether you live in the city or the country. Home Composting in 10 easy steps.
Why make compost?

Composting improves the quality of the soil and helps reduce pollution.
  • Composting reduces the amount of household refuse produced by Quebec families by 30 to 40%, thereby lessening the cost and the air pollution attributable to residual waste transport and disposal.
  • Composting reduces the production of greenhouse gases, which are released when these organic materials left to decompose in landfills and come into contact with heavy metals and other dangerous compounds.

What to compost?

Nitrogen-rich matter
(green or wet matter)
Carbon-rich matter
(brown or dry matter)
Material that should not be composted
  • Fruit and vegetable scraps (even rotten)
  • Egg shells
  • Fresh grass clippings
  • Fresh weed clippings
  • Dry leaves
  • Straw/hay
  • Sawdust
  • Coffee grounds
    (including filters)
  • Tea leaves (including bags)
  • Napkins
  • Paper
    (recycling is recommended)
  • Pasta
  • Bread
  • Rice
  • Peanut shells
  • Fruit pits
  • Natural fibres (cotton, linen, wool, untreated leather…)

  • Meat and Fish
  • Oil (fat)
  • Bones
  • Dairy products
  • Rhubarb leaves (stalks can be composted)
  • Weeds that have gone to seed or with persistent root systems
  • Treated grass
  • Diseased plants or leaves
  • Wood ashes
  • BBQ briquettes
  • Animal or human excrements
    (can contain pathogens)
  • Vacuum dust
  • Materials contaminated by pesticides or other dangerous products (ex. : treated wood)
  • Large quantities of waterlogged material



































Home Composting in 10 Easy Steps
  1. Get a refuse container or pail that you keep on the counter or under the sink.
  2. Post the list of compost matter in plain view.
  3. Get a compost bin from your municipality or nearby warehouse store, or better yet, make one yourself using wood (cedar), wire-mesh, bricks, etc.
  4. Using a shovel, turn the soil in the selected area. A sunny, well-drained area is the ideal spot for a compost bin.
  5. Cover the bottom of the composter with a 5 or 6 cm-layer of small, dry branches.
  6. On this bed of branches, place a layer of dead leaves or earth. This will allow air circulation and improve drainage.
  7. Layer 2 parts of carbon-rich matter (brown or dry matter) to 1 part of nitrogen-rich matter (green or wet mater).
  8. Add finished compost, gardening soil or newspaper to keep flies out of the compost bin.
  9. Aerate the compost pile using an aerator or a pitch fork once a week.
  10. Check the degree of humidity. Add water to the compost until the degree of humidity is similar to that of a damp sponge. Remember that it is always easier to add water than to remove it!
The final product will be rich, dark mulch that has a discernable smell of humus. Use it in your vegetable garden, flower beds, hanging baskets, around perennials, and on the grass. And give back to nature what it has given you!

You live in an apartment or condo?
There are plastic compost bins with lids that are specially designed for use on a balcony.

Composting in winter
You can store your “brown” and “green” materials during winter and use them in the spring.

To store carbon-rich matter, it is recommended to install a storage bin close to the composter. You can make one yourself, using wire-mesh, snow-fencing, assembled wood panels and brick. Because you want to store dry materials only, the bin does not have to be elaborate or insulated against rodents.

To store nitrogen-rich matter, place food scraps in well-sealed containers, for example: paint cans, laundry detergent or cooking oil containers.



What about odours?
Odours are present when there is a lack of air or an imbalance between nitrogen (green/wet) and carbon (brown/dry). Rebalance the pile, aerate, make sure the bottom is not continually waterlogged and that should do it!
