Worm composting in British Columbia is no different than worm composting anywhere else. However, if you happen to live in Vancouver, British Columbia, the city of Vancouver offers apartment residents worm-composting equipment to help reduce food waste in the city.
Worm Composting in Vancouver
Call the city of Vancouver and ask for your worm-composting bin. The container is a plastic bin with air vents to allow adequate air flow and a bottom tray to help keep the area around your bin clean. Once the city delivers your bin, use the bin as you would any commercial or home-built worm-composting bin.
When first setting up your worm-composting bin, and after you harvest your compost, you will need to add bedding. Worm bedding is very simple. If you have a paper shredder, add shredded paper to the bottom of your bin. If you don't, shred paper by hand and add it to the bin. Dry leaves can also work well as worm bedding. Then add a couple handfuls of soil.
Add enough water to your compost bedding to make it wet, but not dripping wet. If you inadvertently add too much water, increase the amount of bedding to compensate for the additional water.
Add 500 red wriggler worms to the wet bedding. These worms will work their way to the bottom of the bedding and begin composting the paper. The 500-worm number is the number appropriate for the city of Vancouver bins. If you use your own bins, start with 1/2 kilo of worms and allow them to reproduce. If you end up with too many worms, some municipalities will offer you a $40 tax receipt for every pound you donate to the city's worm-composting program.
When adding food to your worm-composting bin, dig a hole in the bedding to get the food closer to the worms. Add your food to a different hole or corner in the compost every time to prevent a buildup. Most vegetable-based food waste is suitable for worm composting. Avoid meat and dairy, with the exception of egg shells.
Collecting Your Compost
To collect your compost, put the compost in piles in the light. The worms will move to the centers of the piles to get away from the light. Gather the compost from the outside edges of the piles and return the worms to the bin.
