Master Composter Course – El Cajon

Become a Master Composter! Join us at the beautiful Water Conservation Garden to gain in-depth composting knowledge to expand your sustainable gardening practices. You can earn a certificate of completion after attending all 5 weeks, then go on to receive the Master Composter certification and badge after completing the additional requirements! Meet new people in this fun, hands-on course. Class size is limited. Attendees must preregister.

After completing this 5-week course you will have a better understanding of how to:

* Minimize your carbon footprint and reduce your methane emissions by keeping food and yard waste out of the landfill.

* Create natural nutrient-rich soil amendments with your food and yard waste that help your garden grow.

* Avoid using synthetic fertilizers and pesticides.

* Reduce water use and increase water retention. Compost increases your soil’s water-holding capacity and improves water retention.

The course covers the following topics:

* In-depth traditional composting and the basics of composting with worms (vermicomposting)
