Turn food and garden waste into rich fertilizer with worms

UC Master Gardeners in Stanislaus County presented an all-natural, sustainable solution to disposing garden and food waste during a session for the community on worm composting, reported John Holland in the Modesto Bee.

All it takes is an 18-inch deep bin, equipped for drainage, and a supply of red worms. Provide the worms a substrate that contains a mix of high carbon materials - like shredded paper, dry leaves or sawdust - and kitchen scraps - such as fruit and vegetable cores and peels, leftover grains and coffee grounds. A few months later, the worms will have transformed the contents into a rich organic fertilizer ready to be applied to garden plants.

"It's a great fertilizer," said UC Master Gardener Dennis Lee. "It's very inexpensive for you to produce. You can do it indoors. There's very little odor - actually, no odor.
