Updated 2026-05-20. Choosing a composting method is mostly a question of how much space you have, how much material your kitchen and garden produce, and how much tending you want to do. The three approaches below cover the great majority of home setups.
1. The cold pile
A cold pile is the lowest-effort option. You add greens and browns whenever you have them and let decomposition run at its own pace. There is no schedule and no turning required. The trade-off is time: because the pile rarely heats up, finished compost can take anywhere from several months to about a year, and weed seeds may survive.
This suits gardeners who produce material steadily and are not in a hurry. An enclosed bin keeps a cold pile tidy and helps deter animals, which matters in neighbourhoods with raccoons.
2. The hot pile
A hot, or active, pile is built in a larger batch and turned to add air. With enough material and a reasonable balance of greens and browns, the centre warms up as microbes work, which speeds breakdown and helps reduce weed seeds. The cost is labour and volume: you need a substantial amount of material at once and the willingness to turn it regularly.
Getting the mix right is central to keeping a hot pile working. The companion guide on balancing greens and browns covers how the carbon-to-nitrogen ratio drives that heat.
3. Vermicomposting
Vermicomposting uses red wigglers in a contained bin to process food scraps. Because the bin can live indoors, it keeps working through winter when outdoor piles slow down or freeze. It is well suited to apartments and small households focused on kitchen waste rather than yard trimmings. The bin needs moist bedding, a steady but moderate supply of scraps, and protection from extremes of heat and cold.
Winter in Canada
Outdoor piles do not stop composting in winter so much as pause; activity slows in the cold and resumes as temperatures rise. Many households keep collecting scraps through the cold months and add them in spring, or run an indoor worm bin alongside an outdoor pile.

Choosing between them
| Method | Effort | Best for |
|---|---|---|
| Cold pile | Low | Gardeners with space and patience |
| Hot pile | Higher | Larger gardens, faster results |
| Worm bin | Moderate | Apartments, year-round kitchen scraps |
