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 the Julian Library 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.

In this workshop, we will cover:

• Benefits of composting with worms

• Benefits of using an in-ground worm bin

• Tools, materials, and steps to start an in-ground worm bin

• How to feed your worms and which foods are suitable

• Troubleshooting and maintaining all worm bin styles

• Harvesting and using finished castings

Benefits of in-ground vermicomposting include:

• Greater resistance to temperature extremes

• Increased soil aeration in garden beds

• Save money on purchased worm castings and soil amendments

• Lower your contribution to landfills

• Increase soil health & soil microbiome

• Increase water retention in soil
