Red worms make the best composters and may be purchased through worm breeders or at some garden centres. Moisture and temperature Always keep the bedding as moist as a well-wrung sponge. When adding food to your bin, always bury it under three to six inches of bedding. Imagine the bin is separated into six sections and bury food in a clockwise direction starting with section 1, then 2, then 3 and so on. Once you have reached the last section, return to the first section and start again.
Castings are tiny dark brown droppings with a sweet, rich earthy smell.
Remove the finished compost as soon as possible as worms cannot survive in their own castings. Scoop all of the finished compost to one side of the bin and add fresh bedding and food scraps to the cleared area. The worms will travel from the finished compost to the fresh bedding in search of food. After about a week, you can remove the finished compost and add more fresh bedding. Under direct light, dump the contents of your bin in piles on a sheet of plastic.
