Plant Clinics

Plant clinics provide a time and place for gardeners to bring their gardening questions to us in person. Bring a plant sample sealed in a plastic bag; or photos; or just questions to our table. We have books, sometimes the internet, and experience to draw on. We have informational handouts to share. We love to help you find answers.

San Mateo Arboretum Plant Clinic

The Plant Clinic is held at the San Mateo Arboretum on one Sunday each month, 12 pm to 3 pm, from March through November with the Arboretum plant sale, maximizing Master Gardener outreach to local gardeners.

People visit our table, located in a pleasant spot beneath a rose arbor, with gardening problems, questions, and plant and bug identification. We often draw people to our table with friendly comments and questions, and this often leads to productive gardening discussions. We refer to and show ANR and other science-based publications (primarily from Sunset). We provide Pest Notes as appropriate. We also provide Helpline contact information – and refer any questions we cannot answer to the Helpline.
