Master Gardener Event Information

The San Diego Master Gardener Spring Seminar (Update)

The health and safety of our community is the number one priority for the membership of the UCCE San Diego County Master Gardener Program and the Master Gardener Association of San Diego County. Due to the Coronavirus disease 2019 (COVID-19), the local leadership of the University of California Cooperative Extension and the leadership of the local Master Gardener program have made the decision to follow the University of California directive to cancel or postpone large scale events and meetings.  To this end, we have decided to postpone the Master Gardener 2020 Spring Seminar, scheduled for March 21, 2020. It is our hope that we will reschedule this educational gardening event for the Fall of 2020. For additional information please contact Scott Parker at
