The Solana Center has two upcoming events in October. The first is the Master Composter Course every Thursday from Oct. 5 to Nov. 2 from 5 to 8 p.m. at Cardiff Elementary School. The five-week course is for residents who want to reduce waste, build healthy soil, conserve water, and meet others who care about the earth. The course includes lectures, demonstrations, and a field trip. Encinitas residents receive preferential registration. Cost is $50; scholarships are available. Pre-registration is required.

The second event is the All About Worms Composting Workshop on Saturday, Oct. 7 from 10 a.m. to 12 p.m. at the San Diego Botanic Garden. The free, interactive workshop will teach you how easy it is to compost food waste with red wriggler worms. Pre-registration is required.
