COVID-19 Update
Due to the “Shelter in Place” order issued by all Bay Area counties, including San Mateo and San Francisco, the Master Gardeners are working remotely, effective March 17, 2020. All questions can be directed via email.

Please provide the following information to facilitate a prompt response:

1.   Name
2.   City of residence
3.   Email
4.   Phone, best time to call
5.   Description of problem/question -- for plant or pest problems, please attach photo(s)

Since the Bay Area “shelter in place” requirements have kept many of us at home, gardening in your own backyard has become much more popular! We are seeing an increased interest at the Helpline from both new and established gardeners. It is fun to see many new gardeners asking for advice with questions such as “What do I do with these raised vegetable beds? ”and “How do I start a vegetable garden when I know nothing about gardening?” During the first 30 days of our “shelter in place,” we have had 147 helpline questions, with 17% of them asking about the Spring Garden Market. Many, many thanks to all of our Helpline Volunteers who are working the Helpline remotely and keeping our clients happily gardening!
