A balanced diet for a balanced system
Compost worms can process a wide variety of organic materials, but their health—and the health of your bin—depends on a balanced diet. The key is to manage the ratio of ‘greens’ (nitrogen-rich food scraps) and ‘browns’ (carbon-rich bedding like cardboard). This guide provides clear, item-by-item advice to help you maintain that perfect balance.
Simple practices for happy worms
Mastering what to feed goes hand-in-hand with how you feed. Adopting these simple practices ensures your composting crew stays healthy, active, and processes waste efficiently, keeping your system in effortless balance.
Prepare input
Chop or tear scraps into smaller pieces to speed up transformation.
Bury everything
Cover new food additions with bedding (like cardboard) to prevent pests and odors.
Avoid overfeeding
Add only what your worms can process to keep the bin balanced; observe their consumption.
Balance ‘greens’ & ‘browns’
Include shredded cardboard or paper every time you add food scraps to maintain a healthy ratio.
Monitor moisture
Ensure the bedding stays consistently damp, like a wrung-out sponge, which is vital for worm health.
