Worm composting is a simple, natural method for converting fruit and vegetable scraps from your yard and kitchen into rich nutrients. 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 within a few weeks. Worm composting is so simple that it can be done virtually anywhere: schools, offices, kitchens, or homes.

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