Master Composter Course in Unincorporated San Diego County (5 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.

Become a Master Composter!

  • 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) and compost fermentation (Bokashi).

Master Composter certification requires attendance at 4 out of 5 classes, as well as 30 volunteer hours of related community service.
