Worm Composting

Worm composting (vermicomposting) is a simple method for reusing fruit and vegetable scraps from your kitchen and yard. All you need is a container filled with moistened bedding, worms and food scraps. The worms, with help from micro-organisms, convert the bedding and food waste into compost in only a few weeks. Worm composting is so simple it can be done virtually anywhere: schools, offices, kitchens, or homes.

It is a natural method for recycling nutrients in food waste. The resulting compost is an excellent soil amendment that can be used to make potting soil for house plants or as a fertilizer for your garden. Worm compost is also a rich source of nitrogen, making it an excellent organic fertilizer.

Finally, the worm tea (liquid that is produced during the composting process) is an excellent organic fertilizer and contains many essential minerals and nutrients plants need to grow.

Here is a Fact Sheet.


Follow these seven steps to easy worm composting

3. Feed the worms regularly with:




add these:
  • Fruit and vegetable scraps

    4. Keep the worm bin warm, but not hot, and keep it out of direct sunlight.
    5. Keep bedding moist, but not wet.
    6. Use crushed egg shells or ground limestone to keep the pH neutral (around 7.0).
    7. Feed one end of the bin for two weeks, then harvest your worm compost from the other end.
