Join us at the beautiful Japanese Friendship Garden to gain composting knowledge you can pass along to others.
- Minimize your carbon footprint. Keeping food and yard waste out of the landfill reduces harmful methane gas emissions.
- Use this “waste” to create amendments 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 and improves water retention.
The Master Composter course provides training in the art and science of composting through lectures, demonstrations, and hands-on composting experience. The course covers the following topics:
- Traditional composting & vermicomposting
- Compost bin building and troubleshooting (in teams!)
- Microbiology of composting
- Bokashi fermentation
- Macrodecomposers in your compost pile
- Environmental impacts
- … and much more!
