If you love gardening but have minimal outdoor space, creating compost to feed your plants can be challenging. But worms can create vermicompost for you, and they can do it in very small spaces – even indoors! In this presentation you'll learn the importance of compost for keeping your plants healthy, and find out how to create your own vermicompost using simple materials and kitchen scraps. 

Presenters: 

Jeff Harter removed the lawn from his front yard in 2012 and has been gardening ever since. Years of hit-or-miss efforts convinced him that learning the basics of gardening systematically, from fellow gardening enthusiasts and experts, was the way to achieve better results. Since completing the UC Master Gardener training in 2024, Jeff has continued to acquire knowledge and experience while sharing what he has learned with the gardening community of San Mateo and San Francisco counties.

Kathy Ryan has been vermicomposting off and on since the mid-70s. She describes herself as a lazy composter; the worms do all the work! She’s learned a few things along the way... including -  Don't go on vacation and leave the worms in 90 degree weather! Kathy is a 2024 graduate of the UC Master Gardener program and spends as much time as possible in her local community garden watching the plants, native bees and butterflies.
