Compost Class

Free Composting Classes!

Composting is nature’s recycling system for organic material, such as leaves, grass clippings, yard pruning’s, and certain types of food waste. The result is a soil amendment that helps plants grow healthier.

Basic Composting


Composting is nature’s way of recycling organic matter such as leaves, grass clippings, prunings, barnyard manures, and food scraps. A backyard composting system can be set up to handle plant debris and food scraps, and the resulting compost can be used as a soil amendment in the garden.

Basic Composting Workshops available to Elk Grove Residents

Elk Grove residents can learn about the benefits and techniques of basic composting at workshops conducted each spring and fall by the City of Elk Grove in partnership with the Elk Grove Community Garden.

Each attendee will receive a free starter composting bin at the workshop and free compost will also be available for participants to take home. More deluxe compost bins will be available for purchase at the workshop at a reduced cost.

See above section for workshop dates.

Worm Composting


Worm Composting is a method of composting food scraps that utilizes roughly a thousand or more red worms, a box or bin, and some bedding. Red worms will happily eat leftover food scraps and will provide nutrient-rich worm castings (worm poop) in return. Worm castings are a great fertilizer for use in the garden or on houseplants.

Mulch and Grasscycling

Nearly 30 million tons of compostable organic material ends up in California landfills each year. This wasted organic material generates methane gas at the landfills and contributes to global climate change.

Organic material, such as plant debris and food scraps, can be recycled by mulching, grasscycling, and/or composting.

Mulch is typically chopped or shredded tree prunings that are spread on top of the soil to hold moisture in the soil and to keep weeds down. Mulch can also be used for pathways.

Grasscycling is a method of returning grass clippings to the soil when mowing the lawn.

Compost is a beneficial soil amendment for use in the garden. It can be added to the top of the soil as a mulch, or it can be worked into the soil when preparing a garden area or planting.
