In-Ground Composting with Worms Workshop - Valley Center
Composting with worms, also known as vermicomposting, has benefits for everyone, whether you want to divert kitchen scraps from the landfill, compost in small spaces, or create a natural fertilizer for your plants. In-ground worm composting is especially suited to San Diego County’s climate and is more resilient to the temperature extremes we face, especially during dry, hot months. Join us at Bates Nut Farm to learn how to start and maintain a happy home for red wiggler worms.
All pre-registered attendees who are residents of unincorporated San Diego County can receive a free kitchen scraps container.
