UC Master Gardener Program of San Mateo & San Francisco Counties

We are sorry to report that our annual UC Master Gardener plant sale - scheduled for April 18, 2020 - was canceled due to the Coronavirus (COVID-19) health crisis.

HOWEVER, the good news is you may still be able to purchase some of the select 22 varieties of organic heirloom tomatoes - as well as eggplants and peppers - at Wegman’s Nursery in Redwood City, who are kindly selling them for the Master Gardener Program.
