Please note that during the "Safer-at-Home" LA County Order, workshops will not be provided and the Public Works offices are closed to the public.  The sale of composting bins is only available through the Farmers Market during this time.  

Yard Waste Reduction

Yard waste and food waste (organics) amount to almost 50% of the trash Torrance residents dispose of each year. Most of these materials could be turned into a valuable soil amendment or mulch by composting in your own backyard.

Torrance has a permanent composting and water-wise gardening demonstration site at Columbia Park. It is always open for viewing, and periodic free workshops are offered for more detailed information. It is operated in conjunction with the Los Angeles County Department of Public Works.

Free Workshops

Come and learn about ways to reduce and recycle your yard waste by:

  • Composting: The natural way to mulch and replenish the soil using yard waste and kitchen scraps
  • Grasscycling: Leave your clippings on the lawn and add water and nitrogen to your soil.
  • Worm Composting: Make great compost using your kitchen scraps.
  • Water-wise gardening: Reduce water use and yard trimmings by planting drought-tolerant and low maintenance plants.

Free workshops scheduled in Torrance are held at:

Columbia Park 4045 - 190th Street at the Northwest corner of 190th Street and Prairie Ave.

Beginning workshops are for those interested in learning about backyard composting, worm composting, grass recycling, water-wise gardening, and fire-wise gardening. Advanced workshops are for those interested in learning about organic gardening, good soil, and environmentally responsible ways to control pests, conserving water in the garden, and using native and drought-tolerant plants.

Workshops are on Saturdays starting promptly at 9:30 a.m. to 11:00 a.m.
