About Us

The field trips for kindergarten through 3rd grade are conducted at the UC Master Gardeners Demonstration Garden and Community Education Center. Our four-acre parcel is within Santa Clara County's 287-acre Martial Cottle Park which showcases the area's farming past and celebrates the agricultural heritage of Santa Clara Valley. We demonstrate many aspects of gardening in this parcel, from native plants to vegetables to fruit trees and more. We are located at Martial Cottle Park, 5283 Snell Ave, San Jose, CA 95136.
“Lessons in the Garden” is a garden-based curricula that support California life science standards and nutrition program objectives. A pilot field trip program was conducted in fall 2017. We received the Santa Clara County Open Space Authority (OSA) Measure Q grant which provided transportation funds for six Title 1 and/or schools in low-income communities from 2017-2019.
This program won a 2020 UCCE statewide competition Search for Excellence Award that recognizes outstanding UC Master Gardener projects that supports the mission of the UC Master Gardener Program.
The field trip program has been expanded to include two other trips: “Vermicomposting for Kids” and “Native Bees in Our Backyard.”
During the past year, fall 2023 through spring 2024, we held 17 trips, serving 504 students and 160 parent/chaperones. These trips included several scout troops as well as students from a San Jose State class.
