TENTATIVE: Master Composter Course - City of San Diego (Five Week Course)

 Registration is closed for this event
The five-week Master Composter course provides training in the art and science of composting. Course includes lectures, demonstrations, and a field trip.


Solana Center is continuously monitoring the public health situation regarding COVID-19. We hope to proceed with this outreach at the scheduled date, but will evaluate whether it is safe to do so as the date approaches. All registrants will be notified of cancellation or postponement.

Learn the art and science of composting!

  • Minimize your carbon footprint by keeping food and yard waste out of the landfill, helping reduce harmful methane gas emissions.
  • Use this "waste" to create a nutrient-rich amendment for your garden. Compost use reduces the need for synthetic fertilizers and pesticides. 
  • Reduce water use and increase water retention. Compost increases your soil's water holding capacity by up to 7 times and retains water for up to 7 days.
  • Work with a team to build, maintain and troubleshoot a traditional compost pile. Course will also cover composting with worms (vermicomposting), compost fermentation (Bokashi), and more!

Course includes lectures, demonstrations, and a field trip. 

Our graduates play a variety of roles in their communities, including: building compost piles in community gardens, helping students manage their school worm bins, supporting Solana Center outreach at workshops, school presentations and community events.

Master Composter certification requires attendance at all 5 classes, as well as 30 volunteer hours of related community service.
