Farmers in the Philippines often vermicompost by first pre-composting substrate before letting the worms take over. This breaks down the substrate, making it safe for the worms. For others, including most households, pre-composting would be impractical. Instead, we skip this and use low nitrogen substrate such as newspaper, cardboard and rotten leaves as bedding. Although it is feasible for farmers with large swathes of land and tonnes of waste, it is almost impossible on a small scale. Here is a quick comparison between these two methods:
For most households, it’s impractical to pre-compost your waste. Hence, we recommend preparing carbon-rich or slow-rotting material for your bedding. Examples include: CocoGro Worm Bedding, Newspaper, and Cardboard. If you don’t plan on pre-composting your waste, stick to materials that won’t rot quickly as your bedding. Then, feed your worms once or twice a week with fast-rotting material such as fruit and vegetable scraps, used coffee grounds, and lawn clippings.
