Virtual Master Composter Course

Weekly on Saturdays, September 25 – October 23 10:00-11:30 am

Become a Master Composter! This five-week course offered by Solana Center provides training in the art and science of composting. Course includes weekly webinar meetings with Q&A, take-home lectures, a curated Facebook group, and more!

Topics covered include:

  • How composting minimizes your carbon footprint by keeping food and yard waste out of the landfill, helping reduce harmful methane gas emissions.
  • How to use your “waste” to create a nutrient-rich amendment for your garden. Compost use reduces the need for synthetic fertilizers and pesticides.
  • How to 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.
  • Discover a wealth of composting options for all needs. Course will cover backyard (traditional) composting, composting with worms (vermicomposting), bokashi fermentation, and an array of associated sub-topics.
  • We will also offer a virtual field trip to observe a large-scale composting operation in action!

Master Composter certification requires attendance at all 5 classes, as well as 30 volunteer hours of related community service. Community service opportunities, including virtual and in-person options, will be discussed during the course.

This class will meet Saturdays from 10 – 11:30 AM Sep. 25 – Oct. 23. Priority registration for this course will be offered to residents of unincorporated San Diego County.
