UC Master Gardeners: Composting and Vermiculture for Home Gardeners

April 20, 2021 @ 6:00 pm - 7:30 pm


Learn from our UC Master Gardener volunteers, Joie Spinelli and Dr. Dennis Shusterman, how to turn garden waste into black gold for a healthier garden. This webinar will cover both traditional composting as well as vermiculture, composting with worms. Find out how green and brown organic materials that you already have in your yard are turned into compost and why it is an essential soil amendment.


About the Master Gardeners

He is affiliated with UC San Francisco as a faculty member and UC Berkeley as a practicing physician. His interest in soils and composting grew from his time in Sonoma County as a premed student (and later clinic physician), and was honed by his work with Contra Costa Master Gardeners’ School Gardens group. He has most recently been exploring compost through the lens of a microscope.
